Description

Technical Field

[0001] This utility model belongs to the technical field of ladle feeding equipment, specifically relating to a ladle-based tilting alloy feeding device. Background Technology

[0002] The ladle is an important piece of equipment in the steelmaking process. It holds molten steel, and sometimes a certain amount of alloys such as ferrosilicon, ferromanganese, ferrochrome, ferromolybdenum, ferrotitanium, or ferroaluminum need to be added to adjust the steel composition, regulate the temperature, improve the purity of the steel, and optimize the solidification structure. Currently, most steel companies use a combination of manual direct feeding and automatic silo feeding. When the amount of alloy added is relatively small, manual direct feeding is usually used. This method is relatively simple to operate, but the work efficiency is relatively low, the feeding effect is not ideal, and there are certain safety hazards. When the amount of alloy added is relatively large, automatic silo feeding is used. This method is relatively efficient and the feeding effect is more ideal, but the silo structure design is relatively complex, the operation process is relatively cumbersome, and the investment scale and land area are relatively large. Therefore, it is necessary to develop an alloy adding device based on the ladle.

[0003] After searching, three patent documents were found to be most relevant to this utility model technology. The specific contents are described below:

[0004] Patent document CN 200620090793.1 discloses a rotary feeding device for a ladle turning machine. The device includes a hopper, a gate, a feeding pipe, a rotating device, a support, a working platform, a base, a fixed shaft, a cylinder, a piston rod, a slewing bearing seat, and a feeding device. The device is ingeniously designed and can easily and quickly switch the feeding pipe between the standby position and the working position by manual or pneumatic means. When the feeding pipe rotates from the standby position to the working position, it completes the feeding of guiding sand. When it rotates from the working position to the standby position, it makes room for other operations. It has the characteristics of high working efficiency and small footprint. However, the structural design of the device is relatively complex, so the production cost of the device is relatively high.

[0005] Patent document CN 202120052589.5 discloses a ladle tilting scrap steel feeding device. The device includes an electro-hydraulic actuator, a hopper, an intermediate connecting pipe, a chute, a support, a platform, and control lines. The device is ingeniously designed. When the electro-hydraulic actuator moves upward, it causes the hopper to tilt forward on the support. The scrap steel in the hopper falls from the discharge port into the intermediate connecting pipe, and then into the ladle through the chute. This device can achieve the purpose of adding a sufficient amount of scrap steel into the ladle. It has the characteristics of low production cost, fast feeding speed, and energy saving. However, it occupies a relatively large area. Since the device is designed based on the addition of scrap steel, it is only suitable for adding scrap steel into the ladle and not for adding alloys into the ladle.

[0006] Patent document CN 202223285088.5 discloses a ladle feeding device, which includes a platform beam, a hopper, a vibrating feeder, a weighing hopper, an electro-hydraulic slide valve, a feeding chute device, an electro-hydraulic three-way valve, an alloy baking device, a manual feeding device, and a rotating alloy chute device. The device is ingeniously designed. The use of multiple hoppers can achieve the simultaneous feeding of multiple alloys. When a hopper fails, the device can ensure continuous operation. The use of the alloy baking device can bake the alloy, which helps to increase the tapping temperature and avoid the occurrence of intermittent casting. It has the characteristics of high working efficiency and good stability. However, the structural design of the device is relatively complex, so the production cost of the device is relatively high.

[0049] The assembly process of the ladle-based flipping alloy addition device provided by this utility model

[0050] Combination Figures 1 to 20As shown, firstly, the two first brackets 1 are arranged opposite each other. Then, a linear bearing 8 is placed upright, and a seventh body 801 of the upright linear bearing 8 is placed on the four upper end faces of the four fourth protrusions 105 on the two first brackets 1. Then, the four seventh through holes 803 of the linear bearing 8 and the four first screw holes 108 on the two first brackets 1 are aligned. Then, four bolts 10 are passed through the four seventh through holes 803 and screwed into the four first screw holes 108. In this way, a linear bearing 8 and two first brackets 1 can be assembled.

[0051] Then, the other linear bearing 8 is inverted, and a seventh body 801 of the inverted linear bearing 8 is placed on the four lower end faces of the four fourth protrusions 105 below the two first supports 1. Then, the four seventh through holes 803 of the linear bearing 8 and the four first screw holes 108 below the two first supports 1 are aligned. Then, four bolts 10 are passed through the four seventh through holes 803 and screwed into the four first screw holes 108. In this way, the other linear bearing 8 and the two first supports 1 can be assembled.

[0052] Then, four wheels 13 are inserted into the four first through slots 106 of the two first brackets 1, and the four axle holes of the four wheels 13 are aligned with the eight first through holes 107 of the two first brackets 1. Then, four axles 14 are installed in the four sets of aligned through holes. In this way, the two first brackets 1 and the four wheels 13 can be assembled into a first bracket vehicle.

[0053] Then, the four connecting rods 9 are arranged in pairs facing each other, and the sixteen second through slots 901 are arranged front and back. Then, the four middle parts of the four connecting rods 9 are respectively inserted into the eight eighth through holes 804 of the two linear bearings 8. Then, the two fourth brackets 6 are arranged opposite each other, with the upper fourth bracket 6 inverted and the lower fourth bracket 6 upright. Then, the eight ends of the four connecting rods 9 are respectively inserted into the eight second grooves 607 of the two fourth brackets 6. In this way, the two linear bearings 8, the four connecting rods 9 and the two fourth brackets 6 can be assembled.

[0054] Then, the sixteen second through slots 901 of the four connecting rods 9 and the sixteen sixth through holes 608 of the two fourth brackets 6 are aligned, and then the sixteen thirteenth protrusions 702 of the four fifth brackets 7 are successively inserted into the sixteen sixth through holes 608 of the two fourth brackets 6 and the sixteen second through slots 901 of the four connecting rods 9. In this way, the four fifth brackets 7, the two fourth brackets 6 and the four connecting rods 9 can be assembled.

Then, the other four positioning bolts 4 are simultaneously inverted, and the four ninth protrusions 402 of the four inverted positioning bolts 4 are screwed into the four third screw holes 606 of the inverted fourth bracket 6. In this way, the eight positioning bolts 4 and the two fourth brackets 6 can be assembled.

[0056] Then, the two locking sections 501 of the two rotating shafts 5 are respectively inserted into the four second through holes 204 of the two second brackets 2, and then four positioning pins 12 are installed in the four fourth through holes 503 of the two rotating shafts 5.

[0059] The principle for setting the rotation direction of the rotating shaft in the ladle-based flipping alloy adding device provided by this utility model.

[0060] Combination Figure 1 and Figure 4As shown, for ease of description, let's define the rotating shaft 5 on the left as ① and the rotating shaft 5 on the right as ②. The four bearing segments 502 of the two rotating shafts 5 are all rotating shafts, and the two rotating shafts 5 have a total of two rotating shafts.

[0061] Combination Figure 1 As shown, assuming that initially both second bodies 201 of the two second supports 2 are horizontally positioned, the simplified version is as follows: Figure 21 As shown, along the two rotating axes, ① rotates 90 degrees clockwise and ② rotates 90 degrees counterclockwise. The two second bodies 201 of the two second supports 2 are both vertically arranged. We can define this rotation direction of the two rotating axes 5 as positive.

[0062] Combination Figure 4 As shown, assuming that initially both second bodies 201 of the two second supports 2 are vertically arranged, the simplified version is as follows: Figure 22 As shown, along the two rotating axes, ① rotates 90 degrees counterclockwise and ② rotates 90 degrees clockwise. The two second bodies 201 of the two second supports 2 are both horizontally arranged. We can define the rotation direction of the two rotating axes 5 as opposite.

[0063] The working principle of the ladle-based tilting alloy adding device provided by this utility model

[0064] Combination Figure 1 and Figure 2 As shown, when both second bodies 201 of the two second supports 2 are horizontally arranged, the alloy can be stacked on the two second bodies 201. The four fifth protrusions 202 arranged in pairs can form four walls and prevent the alloy from rolling down from the front and back. The twelfth protrusion 604 of the lower fourth support 6 can prevent the alloy from rolling down from the left and right and prevent the two second supports 2 from flipping outward.

[0065] When ① and ② are rotated forward simultaneously, the two second bodies 201 of the two second supports 2, which are both horizontally arranged, will simultaneously rotate inward by 90 degrees. The two second bodies 201 are both vertically arranged. During this process, with the help of the gravity of the alloy itself, the alloy piled on the two second bodies 201 will fall accurately into the ladle along the two upper surfaces of the two inclined second bodies 201, and can pass through the slag layer covering the surface of the molten steel and enter the molten steel.

[0066] In order to achieve precise rotation angle of the two rotating shafts 5, two servo motors can be installed on the two bearing sections 502 at one end of the two rotating shafts 5. Since the encoder can detect the position, speed and acceleration of the rotor in a timely manner and feed this information back to the servo driver in a timely manner, the servo motors can be precisely controlled. Therefore, by driving the two servo motors, the rotation angle of the two rotating shafts 5 can be precisely adjusted, thereby enabling the two second brackets 2 to be flipped precisely.

[0067] Because the surface of molten steel is covered with a slag layer of a certain thickness, the alloy must have a certain amount of kinetic energy to overcome the resistance and pass through the slag layer smoothly. The kinetic energy of the alloy mainly comes from the conversion of the alloy's gravitational potential energy. The gravitational potential energy of the alloy depends on the alloy's density, volume, gravitational acceleration, and relative drop height. Since the volume and gravitational acceleration of the alloy are usually fixed values, the gravitational potential energy of the alloy mainly depends on the alloy's density and relative drop height.

[0068] When the gravitational potential energy is constant, the relative drop height of the alloy is negatively correlated with the alloy density. For alloys with relatively low density, a relatively high drop height should be selected to obtain a certain high potential energy, thereby obtaining a larger falling kinetic energy, and thus being able to pass through the slag layer and enter the molten steel smoothly. For alloys with relatively high density, a relatively low drop height can be selected to obtain a certain high potential energy, thereby obtaining a larger falling kinetic energy, and thus being able to pass through the slag layer and enter the molten steel smoothly.

[0069] The present invention provides a method for using a ladle-based tilting alloy adding device.

[0070] Assuming that initially both second bodies 201 of the two second supports 2 are horizontally positioned, firstly, four connecting rods 9 are moved downwards at a constant speed along the eight eighth through holes 804 of the two linear bearings 8. Then, the alloy is stably piled on the two second bodies 201 of the two second supports 2. Next, four connecting rods 9 are moved upwards at a constant speed along the eight eighth through holes 804 of the two linear bearings 8. Then, the first support carriage is moved horizontally at a constant speed so that the fourth support 6 can face the ladle. Then, four connecting rods 9 are moved downwards at a constant speed along the eight eighth through holes 804 of the two linear bearings 8 to select a suitable alloy placement height. Then, ① and ② are simultaneously rotated 90 degrees in the forward direction. In this way, the two second bodies 201 of the two second supports 2 will simultaneously rotate inwards by 90 degrees, thus both being vertically positioned. During this process, the alloy piled on the two second bodies 201 will smoothly pass through the slag layer covering the ladle surface and enter the molten steel.

[0071] Additional notes: The ladle-based tilting alloy feeding device provided by this utility model adopts a symmetrical structure design. Multiple specifications of this utility model device should be designed and manufactured to match the diameter and height of the ladle. The appropriate alloy feeding height mainly depends on the density of the alloy. Alloys with relatively low density should be fed at a relatively high height, while alloys with relatively high density can be fed at a relatively low height, so as to obtain a certain high potential energy and thus be able to pass through the slag layer and enter the molten steel smoothly.
