Description

Technical Field

[0001] The present invention relates to a tilting device and a molten material processing method, and more particularly, to a tilting device capable of stably discharging molten material and a method for processing molten material. Background Art

[0002] Since molten steel produced in an electric furnace has a high content of impurity elements, it is difficult to produce high-grade steel using molten steel produced in an electric furnace. Therefore, molten steel produced in an electric furnace is mixed with molten iron produced in a blast furnace to adjust the content of impurity elements in the molten steel, thereby producing high-grade steel in which the content of impurity elements is adjusted.

[0003] Here, the method for mixing molten steel and molten iron is as follows. For example, molten steel produced in an electric furnace is contained in a ladle, and the ladle is set on the upper side of a ladle car containing molten iron produced in a blast furnace. Then, the ladle is tilted to load the molten steel in the ladle into the ladle car, and the molten steel and molten iron are mixed in the ladle car.

[0004] There are two types of equipment for tilting a ladle in a steel mill, one of which is a type of equipment in which a motor is directly connected to the trunnion of the ladle and the motor is driven to tilt the ladle, and the other is a type of equipment in which a lower part of the ladle is supported by a cylinder and the cylinder is operated to tilt the ladle.

[0005] However, since the motor-driven device must directly connect the motor to the trunnion, there are problems that the overall volume is large, a large-capacity motor is required, and installation takes a long time. In addition, the motor-driven device uses a low-speed motor, but the rotation speed of the motor is faster than the recommended rotation speed of the trunnion to stably tilt the ladle. Therefore, there is a problem that it is difficult to accurately control the discharge amount of molten steel due to the rapid rotation of the ladle.

[0006] In addition, the cylinder operation type equipment includes a hydraulic device and a large-capacity cylinder, and the cylinder is lifted by the hydraulic device and tilts the bottom surface of the ladle to tilt the entire ladle. Here, since the center of gravity of the ladle moves horizontally, there is a problem that the flow of molten steel in the ladle is unstable, making it difficult to accurately control the amount of molten steel to be discharged.

[0007] The technology serving as the background of the present disclosure is disclosed in the following patent documents.

Therefore, the molten material can be stably discharged.

[0046] In addition, the molten material can be stably discharged from the container to prevent the discharge flow of the molten material from applying an irregular load to the container, thereby preventing the container from shaking. Therefore, even when the molten material is discharged, the weight of the container can be accurately measured, and the tilting angle of the container can be accurately adjusted using the measured weight value, so that the molten material can be discharged from the container in an accurate amount.

Here, the weight measuring portion 600 may be disposed between the body portion 200 and the top surface of the frame assembly 110. That is, the weight measuring portion 600 may be placed on the top surface of the frame assembly 110, and the body portion 200 may be supported on the weight measuring portion 600.

[0078] The main body 200 may include a plurality of base members 210. For example, the number of base members 210 may be two. Alternatively, the number of base members 210 may be various.

Here, the other direction may be a forward direction or a backward direction.

[0079] The spacing distance of the plurality of base members 210 in one direction may be greater than the size of the container 10 in one direction. Therefore, when the tilting part 500 tilts the container 10 seated on the seating part 300, collision between the container 10 and the plurality of base members 210 may be prevented.

[0080] The body portion 200 may include a plurality of mounting members.

[0082] The placement ring 310 is used to place the container 10. The placement ring 310 can extend horizontally and open vertically from its top surface to the bottom surface to define a through hole. That is, the placement ring 310 can be arranged in a ring shape with a through hole. Here, the container body 11 can be arranged in the through hole. Specifically, at least the lower part of the container body 11 can be inserted into the through hole. In addition, the bottom surface of the protrusion 12 of the container 10 can be placed on each of the two edges of the top surface of the placement ring 310. Here, the two edges can refer to two edges in one direction (for example, the left and right direction). The through hole can be defined in the horizontal center of the placement ring 310.

[0083] The connection member 320 is used to tilt the seat ring 310 by using the rotation force of the tilting part 500, thereby tilting the container 10. That is, the connection member 320 can be rotated by the rotation force of the tilting part 500 to tilt the seat ring 310.

[0084] The connection member 320 may be installed in one direction (for example, in the left-right direction) on each of both sides of the seating ring 310. Alternatively, the connection member 320 may also be provided to protrude from the seating ring 310. The connection member 320 may face the tilting portion 500 in one direction and may be rotatably connected to the tilting shaft member 510 of the tilting portion 500.

[0085] The connecting member 320 may have a lower portion that is arranged in a box shape. The upper portion of the connecting member 320 may have a shape in which its area in another direction is reduced in a direction away from the lower portion of the connecting member 320. Alternatively, the shape of the connecting member 320 may be various. The tilting axis member to be described of the tilting portion 500 may be installed on the upper portion of the outer surface of the connecting member 320. In addition, the placement ring 310 may be connected to the lower portion of the inner surface of the connecting member 320. When the tilting axis member rotates, the connecting member 320 may rotate in the same manner as the tilting axis member, and the lower portion of the connecting member 320 may rotate relative to its upper portion in another direction and in the vertical direction. Therefore, while the tilting axis member is tilted in another direction and in the vertical direction, the placement ring 310 may tilt the container 10 in the same manner.

[0086] The inner surface may refer to a side surface of the connecting member among the side surfaces of the connecting member: the side surface faces the connecting member adjacent to the corresponding connecting member. Here, the outer surface may be a side surface disposed on the opposite side of the inner side, and may be a side surface parallel to the inner surface.

[0087] The outer surface of the connecting member 320 may have a predetermined gap with the inner surface of the base member 210 facing the connecting member. Similarly, the outer surface of the connecting member 320 may have a predetermined gap with the inner surface of each of the mounting members facing the corresponding connecting member. In addition, the outer surface of the connecting member 320 may have a predetermined gap with the inner surface of the tilting part 500 facing the corresponding connecting member. Here, the gap may mean a gap in one direction. Therefore, when the connecting member 320 tilts due to the rotation of the tilting shaft member 510, the connecting member 320 can be prevented from colliding with the base member 210, the mounting member and the tilting part 500.

[0088] The center of gravity of the container 10 can be aligned with the rotation center of the upper portion of the connecting member 320 in another direction (e.g., forward and backward directions). Here, alignment means that the position of the rotation center in one direction and the position of the center of gravity in one direction match each other within an error range. Here, the error range can be the range of the gap between the rotation center and the center of gravity, so that the moment of inertia generated by the gap between the rotation center and the center of gravity is sufficiently smaller than the rotational force generated by the tilting part 500 to suppress or prevent the rotation of the container 10 from being affected. Alternatively, the error range can also mean the error range caused by a measurement error.

[0089] In addition, the center of gravity of the container 10 can be almost aligned with the rotation center of the upper part of the connecting member 320 in the vertical direction. Here, the height of the center of gravity of the container 10 can be increased or decreased within a predetermined range according to the amount of the first molten material M1 contained in the container 10. However, due to the height difference, the intensity of the moment of inertia generated when the container 10 rotates can be fully processed within the intensity range of the rotation force generated by the tilting part 500 to tilt the heavy container 10. In addition, compared with the change of the position of the center of gravity in the forward and backward directions, the change of the height of the center of gravity in the vertical direction can have a minimal effect on the discharge flow of the molten material. Therefore, in one embodiment of the present invention, it is considered that the center of gravity of the container 10 is aligned with the rotation center of the upper part of the connecting member 320 in the vertical direction. The above-mentioned rotation center can mean such a position: at this position, the center of the tilting axis member of the tilting part 500 intersects with the center line passing through the direction in which the tilting axis member extends (for example, in another direction) and the upper part of the outer surface of the connecting member 320. In addition, the center of gravity can be the center of gravity of the container 10 when it is placed on the placement ring 310. Here, the container 10 may be in a state of containing the first molten material M1.

[0090] The coupling portion 400 is used to fix the container 10 mounted on the seating portion 300 to the seating portion 300. The plurality of coupling members 400 may be respectively provided on both edges of the top surface of the seating ring 310 in one direction, and may face the inner surface of the connecting member 320 in one direction. Alternatively, the coupling portion 400 may be provided at each of the two edges of the top surface of the seating ring 310. Alternatively, the coupling portion 400 will be described in the case where two coupling portions 400 are provided at each of the two edges of the top surface of the seating ring 310. Alternatively, even when one coupling portion 400 is provided at each position, or three or more coupling members are provided at each position, the following contents may be similarly or identically applied.

[0091] The coupling part 400 may contact the front and rear surfaces of the protrusion 12 in another direction (for example, in the forward direction and the backward direction), or may face each other at a predetermined distance in another direction. A coupling member may be provided on the front and rear surfaces facing in another direction of the coupling part 400. The coupling member may include at least one of a coupling protrusion and a coupling groove, and may be attached to and detached from the coupling member provided on the protrusion 12. Here, when the coupling member of the coupling part 400 includes a coupling protrusion, the coupling member facing the coupling protrusion of the protrusion 12 may include a coupling groove, and when the container body 11 is placed, the coupling protrusion of the coupling part 400 may be assembled into the coupling groove of the protrusion 12. Here, the coupling protrusion may be arranged to be retractable so that the coupling protrusion is assembled. Here, the coupling protrusion may have a structure of a spherical spring plunger. Alternatively, the coupling protrusion may have a driving structure, such as a hydraulic cylinder or an actuator, and the protrusion and retraction may be controlled by the controller 900. The type of the coupling member may be various.

[0092] Due to the above structure, when the container body 11 is coupled to the seating ring 310, the coupling part 400 may be coupled to the protrusion 12 to prevent the container body 11 from being separated from the seating ring 310 when the seating ring 310 and the container body 11 are tilted. When the coupling part 400 is lifted by hooking the main hook of the crane equipment on the locking part 13, the coupling with the protrusion 12 may be released by the lifting force, or may be released by the control of the controller 900. Therefore, the container body 11 may be lifted to be spaced apart from the seating ring 310.

[0093] When the container 10 is placed on the seating portion 300, the tilting portion 500 generates a rotational force under the control of the controller 900 to tilt the seating portion 300, thereby tilting the container 10. Here, the first molten material M1 may be discharged from the container 10 by the tilting of the container 10. In addition, the tilting portion 500 controls the tilting angle according to the control of the controller 900 to adjust the degree of tilting of the seating portion 300 and the container 10.

[0094] The tilting portion 500 may be disposed on each of the two sides of the placement portion 300 in one direction, supported by the main body portion 200, and connected to the placement portion 300. More specifically, the tilting portion 500 may face the outer surface of the connection member 320 in one direction at both sides of the connection member 320, may be supported on the top surface of each of the plurality of base members 210, and may be connected to the outer surface of the connection member 320. In addition, the connection member 320 may be disposed in the same number as the tilting portion 500. For example, the number of the tilting portions 500 may be two. Hereinafter, the tilting portion 500 will be described in detail based on one tilting portion 500, for example, the tilting portion 500 disposed at the left side of the placement portion 300. Alternatively, the following may be applied identically or similarly to the tilting portion 500 disposed at the right side of the placement portion 300. The front side of the placement portion 300 may be defined as the position where the guide member 130 is disposed, and the left and right sides of the placement portion 300 may be distinguished from each other based on the position.

[0095] The tilting portion 500 may include two or more types of reducers 530 and 540 connected to each other, and an actuator 520 connected to the two or more types of reducers 530 and 540 and supported on the main body portion 200. Here, the two or more types of reducers 530 and 540 may include a gear reducer 530 connected to the actuator 520 and a chain reducer 540 connecting the gear reducer 530 to the seating portion 300.

[0096] That is, instead of increasing the reduction ratio by increasing the size of the reducer when using, for example, one type of reducer, the tilting part 500 can reduce the rotation speed of the rotational force generated by the actuator 520 in different ways in multiple stages without increasing the size of each reducer by combining the gear reducer 530 and the chain reducer 540, thereby significantly increasing the reduction ratio by reducing the rotation speed in two stages in a gear reduction mode and a chain reduction mode. In addition, since the size of the reducer can be reduced, the capacity of the actuator 520 can also be reduced in proportion to the size of the reducer. Therefore, the overall size of the tilting part 500 can be reduced, and the reduction ratio is greatly increased. Hereinafter, the structure of the tilting part 500 will be described in more detail. The tilting part 500 may include a tilting shaft member 510, an actuator 520, a gear reducer 530, a chain reducer 540, a support member 550, and a housing 560.

[0097] The tilting shaft member 510 receives the rotational power from the chain reducer 540 to rotate, thereby tilting the placement part 300. The tilting shaft member 510 can extend in one direction. One end of the tilting shaft member 510 can be arranged to pass through one surface of the housing 560, such as the right surface, and then can protrude from the housing 560 in one direction; or can be exposed from the housing 560 in one direction on one surface of the housing 560, such as the right surface. In addition, one end of the tilting shaft member 510 can be installed on the upper part of the outer surface of the connecting member 320 of the placement part 300. In addition, the other end of the tilting shaft member 510 can extend in one direction within the housing 560. In addition, the tilting shaft member 510 can have a middle part connecting one end thereof to the other end, and the middle part can be rotatably supported on the support member 550 inside the housing 560. The tilting shaft member 510 can be arranged at the height of the center of gravity of the container 10 and aligned with the center of gravity of the container 10. Due to the rotation of the tilt shaft member 510 , the connection member 320 may be rotated in the same manner as the tilt shaft member 510 , and thus the seating ring 310 and the container 10 may be tilted.

[0098] The actuator 520 generates a rotational force and supplies the rotational force to the gear reducer 530. The actuator 520 may include, for example, a motor. Here, the motor may be an inverter-controlled motor. The actuator 520 may be operated by receiving power to generate a rotational force. Alternatively, the type of the actuator 520 and the method of generating the rotational power may be various. The operation of the actuator 520 may be controlled by the controller 900. The actuator 520 may be spaced apart from the tilting shaft member 510 in another direction. That is, the actuator 520 may not be coaxially connected to the tilting shaft member 510. Therefore, the overall size of the tilting portion 500 may be further reduced.

[0099] The gear reducer 530 reduces the rotation speed of the rotation force generated by the actuator 520 in the primary stage. The gear reducer 530 may be connected to the actuator 520 to reduce the rotation speed of the rotation power of the actuator 520 in the primary stage. In addition, the gear reducer 520 may include a gear box 531, a plurality of gears 532 arranged inside the gear box 531 and coupled to each other, and a gear output end 533, the gear output end 533 being connected to the plurality of gears 532, being spaced apart from the tilting shaft member 510 in one direction and being arranged to pass through the gear box 531 in one direction. The number of the plurality of gears 532 for reducing the rotation speed of the rotation force and the coupling structure of the plurality of gears 532 may be various. For example, the plurality of gears 532 may have such a gear number and coupling structure: wherein the rotation speed of 1300rpm input from the actuator 520 is reduced to 1rpm to be output to the gear output end 533. Alternatively, the reduction ratio may be only an example, and the reduction ratio of the gear reducer 530 may be various.

[0100] The gear output end 533 of the gear reducer 530 may be disposed at a height lower than the tilt shaft member 510. Therefore, the tilt shaft member 510 having a relatively large diameter may stably support the load of the chain member 543 of the chain reducer 540 at a height higher than the gear output end 533 having a relatively small diameter. Therefore, the load on the gear output end 533 may be reduced.

[0101] The chain reducer 540 is used to secondarily reduce the rotation speed of the rotation power output from the gear reducer 530 so as to be transmitted to the tilt shaft member 510. Therefore, the chain reducer 540 may be installed on the gear reducer 530 and the tilt shaft member 510 to secondarily reduce the rotation speed of the gear reducer 530 so as to be transmitted to the tilt shaft member 510.

[0102] The chain reducer 540 may include a main toothed member 541 installed on the outer peripheral surface of the other end of the tilting shaft member 510, a secondary toothed member 542 installed on the outer peripheral surface of the gear output end 533 and having an outer diameter smaller than the outer diameter of the main toothed member 541, and a chain member 543 installed to connect the main toothed member 541 to the secondary toothed member 542.

[0103] When the gear output end 533 rotates, the secondary toothed member 542 may rotate in the same manner as the gear output end 533. By the rotation of the secondary toothed member 542, the chain member 543 may rotate along a portion of the outer circumferential surface of the gear output end 533 and a portion of the outer circumferential surface of the tilt shaft member 510, thereby rotating the primary toothed member 541. The primary toothed member 541 may rotate by the circumferential rotation of the chain member 543, thereby rotating the tilt shaft member 510.

[0104] The gear ratio of the primary toothed member 541 and the secondary toothed member 542 may be various. For example, it may have a gear ratio that allows the rotation speed of the rotation force input at 4800 rpm from the gear output end 533 to be reduced to 1 rpm so as to be output to the tilting shaft member 510. Alternatively, the reduction ratio may be only one example, and the reduction ratio of the chain reducer 540 may be various.

[0105] The support member 550 is used to rotatably support the tilting shaft member 510 inside the housing 560. The support member 550 may extend in the vertical direction, the lower end of the support member 550 may be supported on the bottom surface of the housing member 560, and the upper end of the support member 550 may be supported by the tilting shaft member 510. Here, the support member 550 may have a bearing assembly provided at its upper end, and the tilting shaft member 510 may be rotatably supported on the bearing assembly.

[0106] The housing 560 may protect at least a portion of the tilt shaft member 510, the actuator 520, the gear reducer 530, the chain reducer 540, and the support member 550 from the surrounding environment. In addition, the housing 560 may define the appearance of the tilting portion 500. The housing 560 may be arranged so that one end of the tilt shaft member 510 passes therethrough, and the actuator 520, the gear reducer 530, the chain reducer 540, and the support member 550 may be accommodated therein.

[0107] The weight measuring part 600 measures the weight of the first molten material M1 inside the container 10, and outputs the measured weight value to the controller 900. The weight measuring part 600 can measure the weight in real time, and output the measured weight value to the controller 900 in real time. In addition, the weight value measured by the weight measuring part 600 can be used by the controller 900 to adjust the tilting angle of the tilting part 500. Alternatively, the weight measuring part 600 can measure the weight of the first molten material M1 inside the container 10, the weight of the container 10 containing the first molten material M1, the weight of the seating part 300 on which the container 10 is mounted, the weight of the tilting part 500 on which the seating part 500 is supported, and the weight of the main body part 200 on which the tilting part 500 is supported, and then the measured weight value can be output to the controller 900. Hereinafter, the weight measuring part 600 will be described based on the case where the weight measuring part 600 measures the total weight from the first molten material M1 to the main body part 100.

[0108] The weight measuring part 600 may include a high-capacity load cell capable of measuring the weight of a heavy object weighing about 140 tons. The weight measuring part 600 may be disposed at at least four locations horizontally spaced apart from the seating part 300. In addition, the weight measuring part 600 may be installed at a plurality of locations on the lower portion of the body part 200. Specifically, the plurality of weight measuring parts 600 may be installed on the lower portions of the plurality of base members 210, respectively.

[0109] The angle measuring part 700 may measure the angle of the seating part 300 to output the measured angle value to the controller 900. Here, the angle of the seating part 300 may be the same as the angle of the container 10. That is, the angle of the seating part 300 measured by the angle measuring part 700 may be the angle of the container 10. The angle measuring part 700 may include, for example, a digital protractor. Alternatively, the angle measuring part 700 may be of various types, such as an analog protractor and an optical protractor.

[0110] The angle measuring part 700 may be provided on one edge or both edges of the top surface of the placement ring 310 at the lower side of the rotation center of the placement part 300 in another direction. By setting the angle when the top surface of the placement ring 310 is parallel to the horizontal direction to 0 degrees, the angle measuring part 700 may measure the angle defined by the top surface of the placement ring 310 relative to another direction (e.g., the forward direction and the backward direction) as the angle of the placement part 300, and may output the measured angle value. Alternatively, the method of measuring the angle by the angle measuring part 700 may be various. For example, the angle measuring part 700 may measure the angle defined between the top surface of the base member 210 and the top surface of the placement ring 310 in another direction (e.g., the forward direction and the backward direction) as the angle of the placement part 300, and may then output the measured angle value.

[0111] The controller 900 may control whether the tilting part 500 operates according to whether the container 10 is seated on the seating part 300. In addition, the controller 900 may control the tilting angle of the tilting part 500 using the weight value measured by the weight measuring part 600. Here, the controller 900 may control the tilting angle of the tilting part 500 by using one of the sum value and the average value of the weight values ​​measured at a plurality of positions via the weight measuring part 600. Here, the controller 900 may determine the angle of the seating part 300 measured from the angle measuring part 700 as the angle of the container 10, and control the tilting angle of the tilting part 500 based on the determined angle of the container 10.

[0112] The controller 900 may include: an input unit 910, which is used to input a reference amount; a calculator 920, which is used to calculate one of the sum value and the average value of weight values ​​measured at multiple positions, and use the calculated value to calculate the discharge amount of the first molten material M1 discharged from the container 10; and a tilting controller 930, which is used to compare the reference amount previously input into the input unit 910 with the discharge amount obtained by the calculator 920 to increase or decrease the tilting angle according to the comparison result.

[0113] The input unit 910 may include a control computer capable of executing a program. The input unit 910 may be capable of inputting / outputting and storing data from the outside. The input unit 910 may transmit and receive data with the calculator 920 and the tilting controller 930. The reference amount input into the input unit 910 may be a predetermined weight value less than the discharge amount of the first molten material M1 to be discharged from the container 10. For example, when 100 tons of the first molten material M1 must be discharged from the container 10, the reference amount may be set to 90 tons to 80 tons, and the set reference amount may be input into the input unit 910. Here, the numerical value of the above-mentioned target discharge amount and the numerical value of the reference amount are only examples, and the numerical value of the discharge amount and the numerical value of the reference amount may have a variety of values ​​according to the amount and state of the first molten material M1 and the amount and state of the second molten material M2. Here, the state may mean the content of impurity elements in the molten metal. Alternatively, the state may have various meanings, such as the temperature of the molten material, the content of the main component contained in the molten material, etc.

[0114] The calculator 920 may be a control terminal capable of performing electronic calculations. Alternatively, there may be various types of calculators 920. In addition, the calculator 920 may be installed on the input unit 910. In addition, the calculator 920 may add the weight values ​​output in real time from a plurality of (e.g., four) weight measuring parts 600 by time period, and sequentially output the results as calculated values, and may obtain the cumulative value of the discharge amount in the calculated value as the discharge amount of the first molten material M1. For example, if the calculated values ​​from time point 1 to time point 4 are output as 100 tons, 99 tons, 97 tons, and 96 tons, the discharge amount at time point 1 may be calculated as 0 tons, the discharge amount at time point 2 may be calculated as 1 ton, the discharge amount at time point 3 may be calculated as 3 tons, and the discharge amount at time point 4 may be calculated as 4 tons. Alternatively, there may be various ways to obtain the discharge amount of the first molten material M1 according to the weight value output in real time by the calculator 920.

[0115] The tilting controller 930 may be a type of programmable logic controller (PLC). Alternatively, the type of the tilting controller 930 may be various. When the discharge amount of the first molten material M1 obtained by the calculator 920 is less than the reference amount input from the input unit 910, the tilting controller 930 may control the operation of the tilting portion 500 to gradually increase the tilting angle of the tilting portion 500. In addition, when the discharge amount of the first molten material M1 obtained by the calculator 920 is equal to or greater than the reference amount input from the input unit 910, the tilting controller 930 may control the operation of the tilting portion 500 to gradually reduce the tilting angle of the tilting portion 500. Due to the control of the tilting controller 930, the container 10 can be tilted in stages to stably discharge the first molten material M1, and before the discharge amount of the first molten material M1 reaches the target discharge amount to be discharged from the container 10, the tilting angle of the tilting part 500 can be gradually reduced to gradually return the container 10; and when the discharge amount of the first molten material M1 reaches the target discharge amount to be discharged from the container 10, the container 10 can be returned to the tilting angle of the container 10 that prevents the first molten material M1 from being discharged from the container 10. Therefore, a precise amount of the first molten material M1 can be discharged.

[0116] Although embodiments of the present invention have been described above, the present invention may be configured in various ways, including the following additional embodiments.

[0117] Hereinafter, a tilting device according to another embodiment of the present invention will be described.

[0118] Herein, the aforementioned embodiment of the present invention is referred to as a first embodiment, and another embodiment described below is referred to as a second embodiment.

[0119] Furthermore, hereinafter, the second embodiment will be described in detail focusing on features different from those of the first embodiment of the present invention described above, and duplicate descriptions will be omitted or briefly described.

[0120] The tilting device according to the second embodiment of the present invention is configured to discharge molten material from a container 10, and includes: a main body part 200; a placement part 300, which is arranged at the upper part of the main body part 200 to place the container 10; a tilting part 500, which is installed on the main body part 200 and connected to the placement part 300 to tilt the placement part 300; and a damper part 800, which is arranged at each of the two sides of the tilting part 500 and installed at the lower part of the main body part 200 to cushion the impact applied from the container 10 and maintain the horizontality of the main body part 200.

[0121] In addition, the tilting device according to the second embodiment of the present invention may include: a main body support 100, the internal horizontal opening of which allows a transport vehicle 20 for receiving and transporting molten material from the container 10 to pass through, and which is arranged below the main body part 200 so that the main body part 200 is spaced apart from the bottom on which the transport vehicle 20 travels, and includes a guide member 130 for guiding the molten material; and a connecting part 400, which is arranged on the top surface of the placement part 300 to face the tilting part 500 and is connected to the container 10.

[0122] In addition, the tilting device according to the second embodiment of the present invention may include: weight measuring parts 600 respectively installed at a plurality of positions below the main body part 100; an angle measuring part 700 installed on the seating part 300 facing the tilting part 500; and a controller capable of controlling whether the tilting part 500 operates according to whether the container 10 is mounted on the seating part 300, and controlling the tilting angle of the tilting part 500 using the weight value measured by the weight measuring part 600. Here, the controller 900 may determine the angle of the container 10 according to the angle of the seating part 300 measured from the angle measuring part 700 and control the tilting angle of the tilting part 500 based on the determined angle of the container 10.

[0123] Here, the main body support 100, the main body part 200, the placement part 300, the connecting part 400, the weight measuring part 600, the angle measuring part 700 and the controller 900 may have the same configuration as the main body support, the main body part, the mounting part, the connecting part, the weight measuring part, the angle measuring part and the controller of the tilting device in the first embodiment of the present invention described above, and therefore, their description will be omitted here.

[0124] Hereinafter, the tilting portion 500 and the damper portion 800 are described.

[0125] The tilting part 500 generates a rotation force to tilt the seating part 300, thereby tilting the container 10. In addition, the tilting part 500 also controls a tilting angle according to the control of the controller 900 to adjust the degree of tilting of the container 10.

[0126] The tilting portion 500 may face the outer surface of the connecting member 320 in one direction at both sides of the connecting member 320, may be supported on the top surface of each of the plurality of base members 210, and may be connected to the outer surface of the connecting member 320. In addition, the connecting member 320 may be provided in the same number as the tilting portion 500. The tilting portion 500 may include a tilting shaft member 510, an actuator 520, a driving force transmitter (not shown), a support member 550, and a housing 560.

[0127] The tilting shaft member 510 receives the rotational power from the chain reducer 540 to rotate, thereby tilting the seating portion 300. The tilting shaft member 510 may extend in one direction. In addition, the tilting shaft member 510 may be disposed at the height of the center of gravity of the container 10 and aligned with the center of gravity of the container 10.

[0128] One end of the tilt shaft member 510 may be provided to pass through one surface of the housing 560 and protrude from the housing 560, and may be mounted on an upper portion of an outer surface of the connection member 320 of the seating portion 300. In addition, the other end of the tilt shaft member 510 may extend in one direction inside the housing 560. In addition, the tilt shaft member 510 may have a middle portion connecting one end thereof to the other end, and the middle portion may be rotatably supported on the support member 550 inside the housing 560.

[0129] The actuator 520 generates a rotational force and supplies the rotational force to the gear reducer 530. The actuator 520 may be disposed spaced apart from the tilt shaft member 510 in another direction (eg, in the forward direction and the rearward direction).

[0130] The driving force transmitter may be installed to connect the output end of the actuator 520 to the other end of the tilt shaft member 510. In addition, the driving force transmitter may have various rotational force transmission structures within the scope of satisfying that the other end of the tilt shaft member 510 rotates with the rotational force output from the output end of the actuator 520. For example, a chain drive structure may be applied to the driving force transmitter.

[0131] The support member 550 is used to rotatably support the tilt shaft member 510 inside the housing 560. The support member 550 may extend in a vertical direction, the lower end of the support member 550 may be supported on the bottom surface of the housing member 560, and the upper end of the support member 550 may be supported by the tilt shaft member 510.

[0132] The housing 560 may protect at least a portion of the tilt shaft member 510, the actuator 520, the drive force transmitter, and the support member 550 from the surrounding environment. In addition, the housing 560 may define the appearance of the tilt portion 500. The housing 560 may accommodate the actuator 520, the drive force transmitter, and the support member 550 therein.

[0133] The damper portion 800 may buffer the impact applied from the container 10. In addition, the damper portion 800 may maintain the horizontality of the body portion 200. The damper portion 800 may be installed at a plurality of positions on the lower portion of the body portion 200. Specifically, two or more damper portions 800 may be provided for each weight measuring portion 600, and may be provided on each of both sides of each weight measuring portion in another direction (e.g., on each of both sides in the forward direction and the rearward direction).

[0134] In addition, the damper part 800 may have an elastic assembly to elastically support the main body part 200 in the vertical direction. Here, the elastic assembly may include a leaf spring assembly. The damper part 800 may prevent the impact applied to the placement part 300 from the container 10 when the container 10 is installed to the placement part 300 and removed from the placement part 300 from being transmitted to the weight measuring part 600 through the main body part 200. Therefore, the weight measuring part 600 may be prevented from being damaged by the impact when measuring the weight. In addition, the damper part 800 may prevent the impact caused by the change in weight caused by the tilting of the container 10 and the discharge of the first molten material M1 from being transmitted to the weight measuring part 600 through the main body part 200.

[0135] In addition, the damper portion 800 may prevent the body portion 200 from tilting by uniformly elastically supporting the bottom surface of the body portion 200 during tilting of the container 10 and discharge of the first molten material M1 so that the body portion 200 remains horizontal with respect to the top surface of the body support 100 .

[0136] Hereinafter, a tilting device according to another embodiment (i.e., the third embodiment) of the present invention will be described. Hereinafter, the third embodiment will be described focusing on features different from those of the first and second embodiments of the present invention, and their repeated description will be omitted.

[0137] In the aforementioned second embodiment of the present invention, the tilting part has a driving force transmitter, but in the third embodiment of the present invention, the tilting part 500 may have two or more types of reducers connected to each other instead of the driving force transmitter. More specifically, the tilting part 500 according to the third embodiment of the present invention may include a tilting shaft member 510, an actuator 520, a gear reducer 530, a chain reducer 540, a support member 550 and a housing 560. Here, the tilting shaft member 510, the actuator 520, the gear reducer 530, the chain reducer 540, the support member 550 and the housing 560 may have the same configuration as the tilting shaft member, actuator, gear reducer, chain reducer, support member and housing of the tilting part in the first embodiment of the present invention described above, and therefore, their description will be omitted.

[0138] That is, the tilting device according to the third embodiment of the present invention may include a body support 100, a body portion 200, a seating portion 300, a connecting portion 400, a tilting portion 500, a weight measuring portion 600, an angle measuring portion 700, a damper portion 800, and a controller 900. Here, the tilting portion 500 may have the same configuration as the tilting portion of the tilting device according to the first embodiment of the present invention, and the remaining portions except the tilting portion 500 may have the same configuration as the tilting device according to the second embodiment of the present invention.

[0139] The configurations of the tilting devices according to the first to third embodiments of the present invention described above may be combined and changed with each other.

[0140] Figures 4 to 7 2 is a view illustrating the operation of the tilting device according to the embodiment of the present invention.

[0141] Reference Figures 4 to 7 , the operation of the tilting device according to an embodiment of the present invention will be described.

[0142] Reference Figure 4 , the first molten material M1 is contained in the container 10, the container 10 is conveyed to the upper side of the tilting device, and is seated on the seating portion 300. Here, the initial angle θ0 of the container 10 may be, for example, 0 degrees.

[0143] Due to the placement of the container 10, the weight W1 of the container 10 and the first molten material M1 may be distributed to the weight measuring part 600. Here, the sum of the distributed weights W1a may be equal to the weight W1 of the container 10 and the first molten material M1.

[0144] The height of the body part 200 may be reduced from the initial height h0 to the first height h1 due to the weight W1 of the container 10 and the first molten material M1. Here, the damper part 800 may generate an elastic force f proportional to the height reduction amount Δh1 and elastically support the body part 200. Here, the impact may be buffered and the horizontal position of the body part 200 may be maintained.

[0145] Reference Figure 5, the controller 900 may detect the placement of the container 10 and operate the tilting part 500 to generate a rotational force, thereby tilting the container 10 at the first tilting angle θ1. Here, the rotational speed of the rotational force may be reduced by the primary r1 and the secondary r2 in the gear reducer 530 and the chain reducer 540, and the rotational force that reduces the rotational speed to the secondary reduced speed may rotate the tilting shaft member 510 to tilt the container 10. Here, the container 10 may not be tilted at the first tilting angle θ1 all at once, but may be tilted in stages by a unit angle smaller than the first tilting angle θ1, and a predetermined angle holding time may be provided between each tilting angle.

[0146] When the container 10 is tilted and the first molten material M1 is discharged, the reduced weight W2 of the container 10 and the first molten material M1 may be distributed to the weight measuring part 600. Here, the sum of the distributed weights W2a may be equal to the reduced weight W2 of the container 10 and the first molten material M1.

[0147] The height of the body part 200 may increase from the first height h1 to the second height h2 due to the weight W2 of the container 10 and the first molten material M1. Here, the damper part 800 may adjust the elastic force f in proportion to the height increase Δh2 and elastically support the body part 200. Here, the impact may be buffered and the horizontal position of the body part 200 may be maintained.

[0148] Furthermore, when the container 10 is tilted at the first tilting angle θ1 from the initial angle θ0, the position of the center of gravity C and the position of the rotation center passing through the tilting shaft member 510 may match each other.

[0149] The first molten material M1 discharged from the container 10 may be mixed with the second molten material M1 inside the transport vehicle 20 .

[0150] Reference Figure 6, the controller 900 may continuously operate the tilting part 500 to generate a rotational force and tilt the container 10 at a second tilting angle θ2. Here, the rotational speed of the rotational force may be reduced by the primary r1 and the secondary r2 in the gear reducer 530 and the chain reducer 540, and the rotational force that reduces the rotational speed to the secondary reduced speed may rotate the tilting shaft member 510 to tilt the container 10. Here, the container 10 may not be tilted at the second tilting angle θ2 all at once, but may be tilted in stages in units of unit angles, and a predetermined angle holding time may be provided between each tilting angle. For example, the container 10 may be tilted at a tilting angle that is larger than the first tilting angle θ1 by a first unit angle, and then the tilting angle may be maintained for a predetermined period of time. Here, the discharge amount of the first molten material M1 may increase and then gradually decrease. After a predetermined period of time, the container 10 may be tilted to a tilting angle that is larger than the first tilting angle θ1 by a second unit angle, and then the tilting angle may be maintained for a predetermined period of time. In this manner, the first molten material M1 can be stably discharged by gradually tilting at the second tilting angle θ2.

[0151] When the container 10 is tilted and the first molten material M1 is discharged, the further reduced weight W3 of the container 10 and the first molten material M1 may be distributed to the weight measuring part 600. Here, the sum of the distributed weights W3a may be equal to the further reduced weight W3 of the container 10 and the first molten material M1.

[0152] The height of the body part 200 may increase from the second height h2 to the third height h3 due to the weight W3 of the container 10 and the first molten material M1. Here, the damper part 800 may adjust the elastic force f in proportion to the height increase Δh3 and elastically support the body part 200. Here, the impact may be buffered and the horizontal position of the body part 200 may be maintained.

[0153] In addition, when the container 10 is tilted from the first tilting angle θ1 to the second tilting angle θ2, the position of the center of gravity C and the position of the rotation center passing through the tilting shaft member 510 may match each other. The angle measuring part 700 may measure the angle at which the container 10 is tilted to transmit the measured angle value to the controller 900. The controller 900 may determine the tilting state of the container 10 based on the received angle value to control the tilting angle using the determined tilting state.

[0154] Furthermore, the first molten material M1 discharged from the container 10 may be mixed with the second molten material M1 inside the transport vehicle 20 .

[0155] When the first molten material M1 is discharged from the container 10, the discharge amount of the first molten material M1 can be obtained from the sum of the weight values ​​measured by the weight measuring part 600, and when the discharge amount can be compared with the reference amount, then, when the discharge amount is equal to the reference amount, the tilting angle of the container 10 can be reduced from this point.

[0156] Reference Figure 7 , the controller 900 may obtain the discharge amount of the first molten material M1, and when the discharge amount becomes equal to the reference amount, the tilting angle of the container 10 may be reduced from the second tilting angle θ2 to the third tilting angle θ3. Here, the container 10 may stand up due to the reduction of the tilting angle Δθ, and thus, the discharge amount of the first molten material M1 may be reduced.

[0157] Alternatively, even when the tilting angle is reduced, the rotational speed of the rotational force can be primarily reduced by r1 and secondarily reduced by r2 in the gear reducer 530 and the chain reducer 540, and the rotational force that reduces the rotational speed to the secondary reduced speed can rotate the tilting shaft member 510 to reduce the tilting angle of the container 10.

[0158] In addition, the container 10 can be tilted not by reducing the tilting angle Δθ at one time, but by stages in units of angles, and a predetermined angle holding time can be provided between each tilting angle. In this way, the tilting angle can be gradually reduced to the third tilting angle θ3, and the discharge amount of the first molten material M1 can be steadily reduced.

[0159] When the container 10 is tilted and the first molten material M1 is discharged, the further reduced weight W4 of the container 10 and the first molten material M1 may be distributed to the weight measuring part 600. Here, the sum of the distributed weights W4a may be equal to the further reduced weight W3 of the container 10 and the first molten material M1.

[0160] The height of the body part 200 may increase from the third height h3 to the fourth height h4 due to the weight W4 of the container 10 and the first molten material M1. Here, the damper part 800 may adjust the elastic force f in proportion to the height increase Δh4 and elastically support the body part 200. Here, the impact may be buffered and the horizontal position of the body part 200 may be maintained.

[0161] Furthermore, when the container 10 is tilted from the second tilting angle θ2 to the third tilting angle θ3, the position of the center of gravity C and the position of the rotation center passing through the tilting shaft member 510 may match each other.

[0162] In addition, the first molten material M1 discharged from the container 10 may be mixed with the second molten material M1 inside the transport vehicle 20. Thereafter, the controller 900 may continuously reduce the tilting angle of the container 10 to terminate the discharge of the first molten material M1.

[0163] In this way, in an embodiment of the present invention, before the discharge amount of the first molten material M1 reaches the target discharge amount, the controller 900 can use the reference amount to reduce the tilting angle of the container 10 in stages in advance, so that the first molten material M1 can be discharged in an accurate amount.

[0164] Figure 8 is a flow chart illustrating a method for processing molten material according to one embodiment of the present invention.

[0165] In the following, reference will be made to Figure 8 A method for processing molten material according to one embodiment of the present invention is described.

[0166] According to one embodiment of the present invention, a method for processing a molten material includes a process of placing a container 10 containing a molten material (for example, a first molten material M1) in a tilting device, a process of preparing a transport vehicle 20 for containing a second molten material M2 different from the first molten material M1 at the lower side of the container 10, a process of tilting the container 10 by the tilting device, a process of reducing the tilting speed of the container 10, and a process of discharging the first molten material M1 from the container 10 to load the first molten material M1 into the transport vehicle 20.

[0167] First, a container 10 containing a molten material (eg, a first molten material M1) may be placed on a tilting device (S100). Here, the first molten material M1 may include molten steel produced in an electric furnace. In addition, the container 10 may include a ladle.

[0168] That is, the first molten material M1 is produced in the electric furnace and discharged into the container 10. The container 10 containing the first molten material M1 can be transported using a crane device, transported to the upper side of the tilting device, and placed on the placement part 300 (see Figure 4 Here, the container 10 may be coupled to the seating portion 300 using the coupling portion 400 .

[0169] Next, a transport vehicle 20 containing a second molten material M2 different from the first molten material M1 is prepared at the lower side of the container 10 (S200). Here, the second molten metal M2 may include molten iron produced in a blast furnace, and the transport vehicle 20 may include a torpedo vehicle.

[0170] That is, the second molten material M2 is generated in the furnace and transported to the transport vehicle 20. The transport vehicle 20 containing the second molten material M2 travels to the main body support 100 and then stops inside the main body support 100. Here, the opening of the container body 21 of the transport vehicle 20 may be opened and disposed at the lower side of the guide member 130.

[0171] When the transport vehicle 20 is ready at the lower side of the container 10, the container 10 is tilted using the tilting device (S300). Here, the operation of the tilting part 500 can be controlled by the controller 900 to rotate the actuator 520, rotate the tilting shaft member 510 through the actuator 520, and tilt the placement part 300 using the tilting shaft member 510, thereby tilting the container 10 (see Figure 5 ). Here, the rotation center of the tilting shaft member 510 of the tilting device may be aligned with the center of gravity C of the container 10. More specifically, a plurality of tilting shaft members 510 may be provided on both sides of the container 10, and a center line passing through the center of the tilting shaft member 510 in one direction (e.g., in the left-right direction) may be aligned with the center of gravity C of the container 10. Here, the rotation center may be provided on the center line.

[0172] When the container 10 is tilted by the tilting device, the weight of the container 10 may be measured at a plurality of positions of the tilting device using the weight measuring part 600, and the tilting angle of the container 10 may be adjusted using the weight value of the container 10. Here, the weight of the container 10 measured by the weight measuring part 600 may be the weight of the first molten material M1 plus the weight from the main body part 200 to the tilting part 500.

[0173] When the tilting angle of the container 10 is adjusted using the measured weight value, one of the sum value and the average value of the weight values ​​measured at the plurality of positions can be obtained as a calculated value, and the discharge amount of the first molten material M1 discharged from the container 10 can be obtained using the calculated value, and the discharge amount can be compared with the previously input reference amount, and then the tilting angle can be increased or decreased according to the comparison result. That is, if the discharge amount is less than the reference amount, the tilting angle can be increased in stages (see Figure 5 and Figure 6 ), and if the discharge amount is equal to or greater than the reference amount, the tilting angle can be reduced in stages (see Figure 7 ). When the container 10 is tilted, the angle at which the container 10 is tilted may be measured using the angle measuring part 700, and the measured angle value may be transmitted to the controller 900. The controller 900 may control the tilting angle based on the transmitted angle value.

[0174] When the container 10 is tilted by the tilting device, the tilting speed of the container 10 is reduced (S400). Specifically, the rotation speed of the rotational force generated from the actuator 520 can be primarily reduced, and the rotational speed r1 of the rotational force that has been primarily reduced can be secondarily reduced. In addition, the rotational force with the secondary reduced rotational speed can be transmitted to the tilting shaft member 510. Therefore, the tilting shaft member 510 can rotate at the secondary reduced rotational speed r2 to slowly and stably tilt the container 10.

[0175] Reference Figure 3 When the rotation speed of the rotation force is reduced by the primary stage, the rotation speed of the rotation force can be reduced by the gear reduction according to the first reduction ratio using the gear reducer 530. In addition, when the rotation speed of the rotation force that has been reduced by the primary stage is reduced for the second time, the rotation speed of the rotation force that has been reduced by the primary stage can be reduced by the gear reducer 540 by the second reduction ratio that is larger than the first reduction ratio in the chain reduction manner.

[0176] When the container 10 is tilted by the tilting device, the first molten material M1 is discharged from the container 10 and loaded into the transport vehicle 20 (S500).

[0177] That is, the first molten material M1 overflowing from the opening at the upper portion of the container 10 toward the front side of the container 10 by tilting the container 10 and then discharged to the lower side of the container 10 may be guided by the guide member 130 and loaded into the container body 21 of the transport vehicle 20. In addition, a third molten material having an adjusted composition may be generated by mixing the first molten material M1 and the second molten material M2 inside the container body 21. The generated third molten metal may be transported to a secondary refining device or a continuous casting device to be manufactured into high-grade steel.

[0178] According to another embodiment of the present invention, the method for processing molten material may further include a process of maintaining the horizontality of the tilting device while reducing the impact caused by the change in weight applied to the tilting device due to the placement and tilting of the container 10, from the process of placing the container 10 containing the first molten material M1 on the tilting device to the process of discharging the first molten material M1 from the container 10 so as to be loaded into the transport vehicle 20.

[0179] In the process of maintaining the horizontality of the tilting device (S600), as Figures 4 to 7 As shown, the body portion 200 of the tilting device may be elastically supported in the vertical direction at a plurality of positions in the horizontal direction of the tilting device by using the damper portion 800 .

[0180] In the method for processing a molten material according to another embodiment of the present invention, a process of reducing a tilting speed of the container 10 while tilting the container 10 by the tilting device may be omitted.

[0181] The above exemplary embodiments of the present disclosure are for describing the present disclosure, rather than for limiting this specification. It should be noted that the configuration and method disclosed in the above embodiments of the present invention can be combined with each other or cross-applied, and can be combined and modified in various forms, and these combinations and modifications can be considered to be within the scope of the present invention. Therefore, it will be readily understood by those skilled in the art that various modifications and changes can be made to it without departing from the spirit and scope of the present invention as defined by the appended claims.
