Description

[0002] Currently, the world has not been able to effectively solve the problem of waste when crushing raw ingots into small pieces for easy use when preparing brittle metal and material raw material products, including high powder yield and irregular and unqualified products.

[0003] Taking ferrosilicon (FRS) as an example, the current crushing technology commonly used in industry achieves a high powder yield during the crushing process. However, high powder yields during the ferrosilicon crushing process can lead to lower product quality, with severe pulverization resulting in substandard particle size and impacting sales. The market demand and price of ferrosilicon powder are lower than those of lump ferrosilicon, so excessive powder yields can result in economic losses. Furthermore, powder yields during production can easily cause dust pollution, increasing environmental pressure and potentially harming worker health. Furthermore, ferrosilicon powder can exacerbate equipment wear and increase maintenance costs. Due to the difficulty of powder recycling, improper handling can also lead to resource waste.

[0025] The following is combined with Figures 1-14, some embodiments of the present invention will be described in detail. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0026] There are many types of brittle metals. In the following embodiments of the present application, ferrosilicon is used as a specific solution for illustration. It can be understood that the prefabricated defect applying device provided in the present application is applicable to all brittle metal materials, not limited to ferrosilicon.

[0027] The present invention provides a prefabricated defect applying device, as Figure 1 , Figure 2 and Figure 14 shown, including a bracket 1, a lifting module 3, a horizontal moving module 4, an annular guide rail 2 and a defect applying module 8; both ends of the horizontal moving module 4 are respectively arranged on two annular guide rails 2, and the annular guide rails 2 are fixedly arranged on the bracket 1; the defect applying module 8 is connected to the horizontal moving module 4 through the lifting module 3; the defect applying module 8 is as Figure 5 and Figure 6 shown, including a pressing plate and a shuttle-shaped indenter 8.1; the pressing plate is connected to the lifting module 3, and the shuttle-shaped indenter 8.1 is arranged below the pressing plate.

[0028] In this embodiment, in order to make the downward pressure balanced when applying defects and avoid torque, two sets of the horizontal moving module 4, the lifting module 3 and the annular guide rail 2 are respectively used and symmetrically installed on both sides of the device through the bracket 1.

[0029] Specifically, in this embodiment, the defect applying module 8 is the core working module of the entire prefabricated defect applying device, and its function is to directly apply a series of prefabricated defects on brittle metals (such as ferrosilicon ingots) in batches.

[0030] In this embodiment, the defect applying module 8 is mainly composed of a pressing plate and a shuttle-shaped indenter 8.1, etc. A series of holes are prefabricated on the pressing plate to facilitate the shuttle-shaped indenter 8.1 to be placed into the holes and fixedly connected to the pressing plate.

[0031] Specifically, in this embodiment, the shuttle-shaped indenter 8.1 is arranged in an array on the pressing plate, and the specific array method is set according to the required fracture trajectory of ferrosilicon.

[0032] Since high-temperature ferrosilicon is corrosive and prone to react with other metal materials, the shuttle-shaped indenter 8.1 in contact with high-temperature ferrosilicon is made of a ceramic material that does not react with metals to meet the above requirements.

[0033] Specifically, in this embodiment, the defect applying module 8 uses a mechanical lifting module 3 to press defects on high-temperature ferrosilicon with the shuttle-shaped indenter 8.1.

[0034] More specifically, in this embodiment, the defect application module 8 is first driven downward by the lifting module 3 with a fixed stroke. When the shuttle-shaped indenter 8.1 is pressed into the ferro-silicon ingot to a predetermined depth, after the indenter is pressed into the high-temperature ferro-silicon for a period of time, the ferro-silicon cools to a certain temperature, and its fluidity is greatly reduced. At this time, the lifting module 3 drives the defect application module 8 to move upward, and then under the drive of the horizontal movement module 4, it continues to move to the next area where defects need to be applied, realizing the whole process of prefabricated defect application.

[0035] In an alternative embodiment, the defect application module 8 further includes a support plate 10.1 and a flexible protection device 10; the support plate 10.1 is connected to the lifting module 3, and the shuttle-shaped indenter 8.1 is arranged below the pressure plate; a flexible protection device 10 is arranged between the support plate 10.1 and the pressure plate to reduce the impact of the shuttle-shaped indenter 8.1.

[0036] In this embodiment, the pressure plate includes an upper pressure plate 8.3 and a lower pressure plate 8.2. The flexible protection device 10 is arranged between the upper pressure plate 8.3 and the support plate 10.1. When the lifting module 3 drives the defect application module 8 to press downward, it can buffer between the support plate 10.1 and the upper pressure plate 8.3, avoiding damage to the shuttle-shaped indenter 8.1 caused by continued hard pressing after the lower pressure plate 8.2 contacts the ferro-silicon or when the ferro-silicon temperature is too low resulting in too high hardness, realizing the protection of the shuttle-shaped indenter 8.1.

[0037] Specifically, in this embodiment, the upper pressure plate 8.3 and the lower pressure plate 8.2 are connected by bolts, which is convenient for disassembly and assembly to realize the installation and replacement of the indenter.

[0038] More specifically, in this embodiment, the lower pressure plate 8.2 is provided with holes which are arranged in an array. The shuttle-shaped indenter 8.1 is arranged on the upper pressure plate 8.3, and the shuttle-shaped indenter 8.1 is arranged in one-to-one correspondence with the holes. After the shuttle-shaped indenter 8.1 passes through the holes, the upper pressure plate 8.3 and the lower pressure plate 8.2 are fixedly connected.

[0039] In an alternative embodiment, as Figure 5 and Figure 6 shown, the flexible protection device 10 includes a connecting rod 10.2 and a first elastic member; one end of the connecting rod 10.2 is fixedly connected to the upper pressure plate 8.3, the other end of the connecting rod 10.2 passes through the support plate 10.1 and is provided with an end cap 10.3, and the connecting rod 10.2 is slidably connected to the support plate 10.1; the first elastic member is arranged between the support plate 10.1 and the upper pressure plate 8.3.

[0040] In this embodiment, the function of the flexible protection device 10 is to absorb kinetic energy and protect the defect application module 8 from being damaged by rigid impact.

[0041] Specifically, in this embodiment, the flexible protection device 10 is composed of components such as an end cap 10.3, a connecting rod 10.2, a first elastic member 10.4, a pressure sensor, and a spring washer. In cooperation with structures such as a support plate 10.1 and an upper pressing plate 8.3, it realizes the safety protection of the defect application module 8.

[0042] More specifically, in this embodiment, a countersunk through hole is provided on the support plate 10.1, and an elastic washer is provided in the countersunk hole. One end of the connecting rod 10.2 is fixedly connected to the upper pressing plate 8.3, and the other end passes through the countersunk through hole and is fixedly connected to the end cap 10.3. In the natural state, the end cap 10.3 falls into the countersunk hole of the countersunk through hole.

[0043] In this embodiment, the first elastic member is arranged on the connecting rod 10.2, and its two ends are respectively abutted against the upper pressing plate 8.3 and the support plate 10.1, and the pressure data is monitored in real time through the pressure sensor.

[0044] Specifically, in this embodiment, the first elastic member is a compression spring. The spring washer is sleeved on the connecting rod 10.2 and is installed between the compression spring and the upper pressing plate 8.3.

[0045] When applying a defect, the support plate 10.1 is driven by the lifting module 3 to descend. After the shuttle-shaped indenter 8.1 contacts the ferrosilicon, the lifting module 3 drives the pressing plate to continue pressing down. At this time, the support plate 10.1 continues to move downward, thereby compressing the compression spring. The pressure is transmitted to the upper pressing plate 8.3 through the elastic force of the compression spring, and the upper pressing plate 8.3 is forced to drive the shuttle-shaped indenter 8.1 to press down to create a defect.

[0046] If the ferrosilicon is too hard due to too low temperature at this time, but the lifting module 3 is still in the descending state, the compression spring can be further compressed to ensure that the shuttle-shaped indenter 8.1 made of brittle ceramic material will not be damaged due to extrusion. At the same time, the pressure sensor will detect abnormal pressure and feedback the abnormal data to the control terminal, thereby terminating the lifting module 3 from driving the defect application module 8 to continue pressing down.

[0047] In special cases, uneven hardness during the cooling process of ferrosilicon will cause the pressing plate to tilt slightly, resulting in the pressing plate and the equipment bearing lateral torque. To reduce the lateral torque borne by the equipment and improve its service life, the elastic washer installed at the gap between the support plate 10.1 and the upper pressing plate 8.3 can absorb the deformation generated by the torque and reduce the lateral force received by the equipment, ensuring that the equipment will not be damaged when subjected to greater stress.

[0048] According to Hooke's law: Let the elastic coefficient of the compression spring be k and the deformation of the compression spring be x, then the elastic force F of the compression spring is:

[0049] At the same time, it can be known that the downward pressure F of the shuttle-shaped indenter 8.1 on the defect application module 8 8.1is the sum of F and the self-weight G8 of the defect application module 8, i.e.:

[0050] In this embodiment, according to the depth of the prefabricated defect that needs to be applied to the high-temperature ferrosilicon, the stroke H of the lifting module 3 is selected appropriately, and a spring with an appropriate elastic coefficient k is selected. After installing the flexible protection device 10 by disassembling the end cover 10.3, the work of applying defects to the high-temperature ferrosilicon can be carried out.

[0051] When the horizontal movement module 4 drives the defect application module 8 to reach the set area where the prefabricated defect is to be applied, the lifting module 3 drives the defect application module 8 to descend. The spindle-shaped indenter 8.1 starts to contact the high-temperature ferrosilicon and press into the not-yet-solidified high-temperature ferrosilicon. At the same time, the compression spring is compressed by the reaction force of the high-temperature ferrosilicon. After the lifting module 3 reaches the maximum stroke H, the compression spring is no longer compressed, but continues to slowly push the upper pressure plate 8.3, the lower pressure plate 8.2, and the spindle-shaped indenter 8.1 to continue pressing down under the action of the elastic force F until the elastic force F is offset by the reaction force of the high-temperature ferrosilicon. At this time, the depth that the spindle-shaped indenter 8.1 presses into the high-temperature ferrosilicon is equal to the predetermined depth of the prefabricated defect.

[0052] When the high-temperature ferrosilicon cools to a certain temperature, at this time the high-temperature ferrosilicon just does not have fluidity, the lifting module 3 drives the defect application module 8 to rise and return to the original state, and the compression spring returns to its natural state, and the application of the prefabricated defect in this area is completed.

[0053] In an alternative embodiment, as Figure 6 shown, the lifting module 3 includes a hydraulic cylinder; the cylinder body of the hydraulic cylinder is arranged on the horizontal movement module 4, and the piston rod of the hydraulic cylinder is connected to the support plate 10.1.

[0054] In this embodiment, the function of the lifting module 3 is to drive the defect application module 8 to move vertically to realize the downward pressing function of the spindle-shaped indenter 8.1 to apply the prefabricated defect, and it is mainly composed of a hydraulic cylinder.

[0055] Specifically, in this embodiment, the hydraulic cylinder is fixed on the horizontal movement module 4 by screws, and the rod head of the piston rod of the hydraulic cylinder is connected to the support plate 10.1 by screws.

[0056] Since the application of the hole-shaped prefabricated defect is realized by the vertical downward pressure of the spindle-shaped indenter 8.1, a hydraulic cylinder with a predetermined stroke h can be selected to drive the pressure plate and the spindle-shaped indenter 8.1 in the working mechanism to move vertically to ensure a better effect of applying the prefabricated defect.

[0057] After the defect application module 8 is moved to the predetermined defect application area by the horizontal movement module 4, the lifting module 3 is activated. The hydraulic piston rod with a set stroke pushes the support plate 10.1 and the defect application module 8 to press vertically downward, creating a prefabricated defect on the ferrosilicon. After a certain period of time, when the ferrosilicon solidifies to a predetermined degree, the hydraulic piston rod drives the defect application module 8 to rise vertically to the initial position above the ferrosilicon, and then it is moved to the next defect application area under the drive of the horizontal movement module 4 to start a new round of defect application operations.

[0058] In an alternative embodiment, as Figure 3 and Figure 4 shown, the horizontal movement module 4 includes a support shaft and a moving component; there are two moving components, which are respectively arranged at both ends of the support shaft; the moving component includes a main roller 4.4, a power device, and a transmission device 4.2; the main roller 4.4 is rotatably arranged at the end of the support shaft and is arranged on the annular guide rail 2; the power device is fixedly arranged on the support shaft and is connected to the main roller 4.4 through the transmission device 4.2.

[0059] In this embodiment, the support shaft is divided into two parts, namely the horizontal shaft 9 and the vertical shaft 11, and the horizontal shaft 9 and the vertical shaft 11 are fixedly connected by welding.

[0060] Specifically, in this embodiment, the number of vertical shafts 11 is two, which are respectively arranged below the opposite ends of the horizontal shaft 9. The hydraulic cylinder of the lifting module 3 is fixed on the vertical shaft 11. The lower end of the vertical shaft 11 passes through the support plate 10.1, and the vertical shaft 11 is slidably arranged with the support plate 10.1. The piston rod of the hydraulic cylinder is fixedly connected to the support plate 10.1, and can drive the support plate 10.1 to move up and down on the vertical shaft 11. The vertical shaft 11 is equivalent to the guide rod of the support plate 10.1. There is an end plate 11.1 at the lower end of the vertical shaft 11, which can limit the maximum stroke of the support plate 10.1 and prevent the support plate 10.1 from detaching from the vertical shaft 11. The end plate 11.1 and the vertical shaft 11 are fixedly connected by bolts. By disassembling the end cover 10.3, it is convenient to disassemble and install the support plate 10.1.

[0061] In this embodiment, the function of the horizontal movement module 4 is to drive the defect application module 8 to move horizontally along the length direction of the casting pool, so as to realize the operation of applying defects to the ferrosilicon in batches.

[0062] Specifically, in this embodiment, there are two moving components, which are respectively at both ends of the horizontal shaft 9.

[0063] More specifically, the moving component includes a power device, a transmission device 4.2, and a main roller 4.4.

[0064] Among them, the power device is a motor 4.1, which is fixed on the support shaft by bolts and can achieve fast, slow output, pause, start, and reverse under manual or automatic control.

[0065] The transmission device 4.2 is a gear transmission, including a driving wheel 4.6, a driven wheel 4.7 and a bushing 4.3. The driving wheel 4.6 is coaxially and fixedly connected to the output shaft of the motor 4.1. The driven wheel 4.7 is coaxially and fixedly connected to the bushing 4.3. The driving wheel 4.6 meshes with the driven wheel 4.7. The bushing 4.3 is rotatably arranged on the cross shaft 9. The main roller 4.4 is fixedly connected to the bushing 4.3. After the motor 4.1 is started, it can drive the driving wheel 4.6, the driven wheel 4.7, the bushing 4.3 and the main roller 4.4 to rotate, so that the main roller 4.4 can roll on the annular guide rail 2, realizing the horizontal movement of the defect application module 8.

[0066] In an alternative embodiment, a reversing device 5 is fixedly arranged on the support shaft for controlling the horizontal movement module 4 to change the moving direction.

[0067] Specifically, in this embodiment, through the setting of the reversing device 5, the rotating direction of the main roller 4.4 is changed, so that the main roller 4.4 can roll back and forth on the annular guide rail 2, realizing the horizontal reciprocating movement of the defect application module 8.

[0068] In an alternative embodiment, as Figure 12 and Figure 13 shown, the reversing device 5 includes a reversing seat 5.2, a reversing ejector rod 5.3, a reversing push rod 5.4, a reversing switch 5.6, a second elastic member 5.9, a third elastic member 5.5 and a reversing baffle 5.1; the number of the reversing baffles 5.1 is two, which are respectively arranged at the front and rear ends of the annular guide rail 2. The reversing ejector rod 5.3 is slidably arranged on the reversing seat 5.2 and can abut against the reversing baffle �.1; the reversing push rod 5.4 is arranged in the reversing seat 5.2 and is connected to the reversing ejector rod 5.3 through a connecting rod 5.8; the second elastic member 5.9 connects the connecting rod 5.8 and the reversing seat 5.2; there are two reversing switches 5.6, both of which are arranged in the reversing seat 5.2; the third elastic member 5.5 is arranged at both ends of the reversing push rod 5.4, and the third elastic member 5.5 can contact the reversing switch 5.6 when the reversing ejector rod 5.3 abuts against the reversing baffle 5.1.

[0069] In this embodiment, the reversing baffles 5.1 are fixed at the front and rear ends of the annular guide rail 2. The reversing ejector rod 5.3, the reversing push rod 5.4 and the connecting rod 5.8 are connected to form an overall I-shaped structure. The reversing ejector rod 5.3 is slidably connected to the reversing seat 5.2, and the sliding direction is the front and rear direction of the horizontal movement module 4.

[0070] In this embodiment, the commutation seat 5.2 is provided with two commutation switches 5.6, which are respectively arranged corresponding to the commutation push rods 5.4. When the commutation seat 5.2 moves with the horizontal shaft 9 to a certain position and one end of the commutation ejector rod 5.3 abuts against one of the commutation baffles 5.1, the corresponding commutation push rod 5.4 just contacts the corresponding commutation switch 5.6. Press the commutation switch 5.6, and the motor 4.1 rotates in the reverse direction; when the commutation seat 5.2 moves in the reverse direction with the horizontal shaft 9 to a certain position, the other end of the commutation ejector rod 5.3 abuts against the other commutation baffle 5.1. At this time, the other end of the commutation push rod 5.4 just contacts the other commutation switch 5.6. After pressing this commutation switch 5.6, the motor 4.1 reverses again.

[0071] Specifically, in this embodiment, second elastic members 5.9 are arranged on both sides of the connecting rod 5.8. The second elastic members 5.9 are compression springs, and both ends of the compression springs are respectively abutted against the connecting rod 5.8 and the commutation seat 5.2, which can reduce the impact force between the commutation ejector rod 5.3 and the commutation baffle 5.1. At the same time, after the commutation ejector rod 5.3 is separated from the commutation baffle 5.1, the connecting rod 5.8 is centered and reset, and at the same time drives the commutation push rod 5.4 to reset, so that the push plate 5.7 is separated from the commutation switch 5.6, avoiding the push plate 5.7 on the commutation push rod 5.4 from pressing the commutation switch 5.6 for a long time, and ensuring the normal use effect and service life of the commutation switch 5.6.

[0072] Specifically, in this embodiment, the end of the commutation ejector rod 5.3 is provided with a rolling bearing.

[0073] During the process of the commutation ejector rod 5.3 contacting the commutation baffle 5.1, the acting force exerted by the commutation ejector rod 5.3 on the commutation baffle 5.1 is oblique, that is, there is both a horizontal acting force and a vertical acting force. The commutation baffle 5.1 is vertically arranged, and it can offset the horizontal force of the commutation ejector rod 5.3. The vertical acting force on the commutation ejector rod 5.3 will drive the commutation ejector rod 5.3 to generate relative displacement on the commutation baffle 5.1, thus generating friction.

[0074] To reduce the influence of friction on the commutation ejector rod 5.3 and the commutation end plate 5.1 and ensure the service life of the commutation ejector rod 5.3 and the commutation end plate 5.1, in this embodiment, a rolling bearing is arranged at the end of the commutation ejector rod 5.3. Its horizontal acting force is not affected, while the vertical acting force will become a rotational acting force, thereby reducing friction and ensuring the use effect and service life.

[0075] Specifically, in this embodiment, the end of the commutation push rod 5.4 is provided with a third elastic member 5.5, specifically a compression spring, which can prevent hard contact between the commutation push rod 5.4 and the commutation switch 5.6 when the commutation push rod 5.4 contacts the commutation switch 5.6 and damage the commutation switch 5.6. A push plate 5.7 can be provided at the end of the compression spring, and the commutation switch 5.6 is contacted through the push plate 5.7 to increase the contact area. When the commutation push rod 5.4 moves with the commutation seat 5.2, when the commutation ejector rod 5.3 abuts against the commutation baffle 5.1, the commutation seat 5.2 continues to move horizontally, so that the compression spring on the commutation push rod 5.4 abuts against the commutation switch 5.6 at the rear. The commutation switch 5.6 is squeezed through the push plate 5.7, the commutation switch 5.6 is pressed, the motor 4.1 commutes, and the commutation seat 5.2 moves in the reverse direction. Under the action of the second elastic member 5.9, the commutation push rod 5.4 is separated from the commutation seat 5.2.

[0076] In an alternative embodiment, as Figure 7 and Figure 8 shown, the annular guide rail 2 includes an inner rail 2.2 and an outer rail 2.1; both the inner rail 2.2 and the outer rail 2.1 are fixedly arranged on the bracket 1, and track grooves 2.5 are arranged on both the inner rail 2.2 and the outer rail 2.1. The main rollers 4.4 of the horizontal movement module 4 are rotatably arranged in the track grooves 2.5; the cross section of the track groove 2.5 is V-shaped, and the track grooves 2.5 on the inner rail 2.2 and the outer rail 2.1 are arranged oppositely.

[0077] In this embodiment, both the inner rail 2.2 and the outer rail 2.1 are fixedly installed on the bracket 1 by bolts, and the uppermost layer of the guide rail of the outer rail 2.1 can be detached separately, which is convenient for equipment installation.

[0078] In this embodiment, the track grooves 2.5 on the inner rail 2.2 and the outer rail 2.1 are arranged oppositely and are both set to be V-shaped, which is matched with the shape of the main rollers 4.4 on the horizontal movement module 4, that is, the outer shape of the main rollers 4.4 is also set to be V-shaped to increase the contact area between the main rollers 4.4 and the track grooves 2.5 and increase the friction force between the two.

[0079] Specifically, in this embodiment, the main rollers 4.4 are made of rubber-like materials, so that they have a larger friction coefficient and reduce the generation of sliding friction; at the same time, the wheeled movement method has the characteristics of rapid and flexible movement; considering that the defect application device is relatively close to the ferrosilicon in the vertical direction, in order to prevent the device from affecting the subsequent ferrosilicon demolding process, the guide rail is set as an approximately elliptical track, so that after the defect application work is completed, the device can move up to the upper guide rail to leave enough demolding space.

[0080] The specific operation process is as follows: When starting work, the motor 4.1 of the horizontal moving module 4 drives the "V"-shaped main roller 4.4 to drive the defect application module 8 to move precisely to the working position and stop. After the defect application in this area is completed, the motor 4.1 starts and drives the main roller 4.4 to drive the defect application module 8 to move precisely to the next working area and pause, and the work is repeated in this way.

[0081] After the defect application operation on the whole ferrosilicon ingot is completed, the defect application module 8 is driven by the main roller 4.4 driven by the motor 4.1 to complete the "human" shape rise through the annular guide rail 2: the motor 4.1 drives the device to first move forward and upward to the "human" shape vertex at the front end of the guide rail. When it is about to reach the front end vertex, the front end of the reversing push rod 5.3 contacts the reversing baffle 5.1, but the defect application module 8 is still moving forward, that is, the reversing push rod 5.3 moves backward relative to the reversing device 5. When the defect is applied, the defect application module 8 is moved forward. When the defect application module 8 reaches the apex of the "H" shape at the front of the guide rail, the push plate 5.7 at the rear end of the reversing push rod 5.4 presses the reversing switch 5.6. Then, the motor 4.1 outputs the reversing signal, driving the defect application module 8 to continue its upward and downward ascent, completing the "H" shape and leaving ample space for the ferrosilicon ingot to be demolded. At the same time, the reversing push rod 5.3 gradually moves away from the reversing baffle 5.1 at the front of the guide rail, and the reversing push rod 5.4 in the reversing device 5 gradually returns to its normal state under the action of the return spring. Once the demolding process is completed, the prefabrication defect application process for the entire ferrosilicon ingot is complete. After that, the main roller 4.4 driven by the motor 4.1 quickly moves along the upper layer of the circular guide rail 2 to the rear end of the guide rail, and then moves obliquely backward and downward along the rear end track of the guide rail. When the reversing push rod 5.3 contacts the reversing baffle 5.1 at the rear end, the push plate 5.7 on the reversing push rod 5.4 just presses the reversing switch 5.6 on the reversing seat 5.2 to complete the output reversal of the motor 4.1.

[0082] At the same time, the reversing push rod 5.3 gradually moves away from the rear end baffle of the guide rail, and the reversing push rod 5.4 in the reversing device 5 gradually returns to its natural state under the action of the second elastic member 5.9.

[0083] Afterwards, the motor 4.1 drives the main roller 4.4 to move the defect applying module 8 obliquely forward and downward to the lower horizontal section of the annular guide rail 2, and slowly and accurately moves to the first area where defects need to be applied, starting the next batch of defect application operations.

[0084] In this embodiment, the outer surface of the main roller 4.4 is made of rubber, and the material of the annular guide rail 2 is steel.

[0085] Specifically, the friction coefficient between rubber and steel is as follows: Static friction coefficient ≈0.8; sliding friction coefficient ≈0.72; rolling friction coefficient ≈0.55。

[0086] On the horizontal guide rail, when the moving speed of the device is v, the moving distance of the device by inertia after the motor 4.1 stops: Rolling friction:

[0087] Kinetic energy:

[0088] According to the law of conservation of energy: That is

[0089] The braking distance after the motor 4.1 stops is obtained:

[0090] Among them, N is the normal pressure on the fixed guide rail surface; m is the mass of the moving device; is the moving speed of the moving device; is the included angle of the "V" groove on the fixed guide rail; 。

[0091] Therefore, when the motor 4.1 drives the device to move at a speed Before the predetermined defect application area The motor 4.1 should be paused at a distance.

[0092] On the slope guide rail, in the inclined state with a slope of α, the friction force received by the main roller 4.4:

[0093] The component force F1 of the gravity G along the inclined plane downward is:

[0094] If , there will be no slipping phenomenon. According to Expression, obviously when The larger it is, the easier it is to have a slipping phenomenon.

[0095] The maximum inclination angle of all inclined section guide rails of this device , at this time:

[0096]

[0097] Substitute Into the formula to get:

[0098]

[0099] Obviously: Always holds.

[0100] Therefore, when the main roller 4.4 is in the "climbing" state on any non-horizontal section, it will not slip due to insufficient frictional force.

[0101] In an alternative embodiment, as Figure 7 and Figure 8 shown, a return module 6 is further provided on the annular guide rail 2 for limiting the position when the horizontal movement module 4 is lifted; the return module 6 includes a sprocket wheel 6.3, a ratchet wheel 6.1 and a pawl 6.2; the pawl 6.2 is provided on the annular guide rail 2, the ratchet wheel 6.1 is fixedly connected with the sprocket wheel 6.3, and the pawl 6.2 is arranged in cooperation with the ratchet wheel 6.1; a limiting groove 6.4 is provided on the sprocket wheel 6.3, and a part of the horizontal movement module 4 on the annular guide rail 2 can enter the limiting groove 6.4 and drive the sprocket wheel 6.3 to rotate.

[0102] In this embodiment, the function of the return module 6 is to guide and support the horizontal movement module 4 and the defect application module 8 to move from the lower half circle of the annular ejector rod to the upper half circle, facilitating the demolding of the ferrosilicon ingot and the return of the defect application module 8 to the initial position of defect application.

[0103] In this embodiment, the return module 6 is composed of a ratchet wheel 6.1, a pawl 6.2, a sprocket wheel 6.3 and a fixed guide rail, etc.

[0104] Specifically, in this embodiment, the sprocket wheel 6.3 is installed on the protruding part at the front end of the annular guide rail 2 through a bearing, that is, the top of the front end; the pawl 6.2 is installed on the annular guide rail 2 and cooperates with the ratchet wheel 6.1, so that the ratchet wheel 6.1 can only rotate in one direction; the ratchet wheel 6.1 and the sprocket wheel 6.3 are coaxially fixedly connected to realize the one-way rotation limit of the sprocket wheel 6.3.

[0105] More specifically, in this embodiment, the side wall of the limiting groove 6.4 of the sprocket wheel 6.3 is a V-shaped groove, and an auxiliary roller 4.5 is fixedly arranged on the bushing 4.3 of the horizontal movement module 4, which is coaxially arranged with the main roller 4.4. After the bushing 4.3 enters the limiting groove 6.4 under the action of the main roller 4.4, the auxiliary roller 4.5 enters the limiting groove 6.4 and cooperates with the V-shaped groove in the limiting groove 6.4. After the motor 4.1 rotates in the reverse direction, the horizontal movement module 4 is taken out of the limiting groove 6.4 through the auxiliary roller 4.5 and enters the track between the inner rail 2.2 and the outer rail 2.1, avoiding the situation that the main roller 4.4 cannot drive the horizontal movement module 4 to move in a suspended state when the motor 4.1 just changes direction.

[0106] After the work of applying prefabricated defects to the whole ferrosilicon ingot is completed, the defect application module 8 needs to move upward to reserve space for the demolding of the ferrosilicon ingot and move the defect application module 8 to the starting position of the whole defect application process.

[0107] The specific process is as follows: After the defects are applied to the entire ferrosilicon ingot, the motor 4.1 drives the "V"-shaped main roller 4.4 to rotate, further driving the defect application module 8 to move obliquely forward and upward along the last section in front of the fixed guide rail. When it moves to the inflection point at the end of the annular guide rail 2, the reversing device 5 in the horizontal movement module 4 realizes the reverse rotation direction under the condition of constant motor 4.1 speed. The main roller 4.4 is supported by the grooved pulley 6.3 that can only rotate in one direction, realizing the movement obliquely backward and upward (the movement trajectory is similar to a "herringbone" shape) until the device rises to the horizontal section above the annular guide rail 2, and the function of the return module 6 ends here. Then, the subsequent demoulding process of the ferrosilicon ingot and the reset of the next round of prefabricated defect application process of the device can be carried out.

[0108] In this embodiment, the grooved pulley 6.3 is provided with a number of limit grooves 6.4, and a specific angle is set between adjacent limit grooves 6.4. After the device completes the return movement in the previous round, the next limit groove 6.4 of the grooved pulley 6.3 exactly corresponds to the starting point of the next round of return movement, realizing automatic return.

[0109] In an alternative embodiment, as Figure 9 、 Figure 10 and Figure 11 shown. An active guide rail 7 is also provided on the annular guide rail 2 for limiting when the horizontal movement module 4 is falling; the active guide rail 7 is rotatably arranged on the inner rail 2.2; one end of the active guide rail 7 is connected to the inner rail 2.2 through the fourth elastic member 14, and the other end can block the track between the inner rail 2.2 and the outer rail 2.1.

[0110] The return module 6 is for the horizontal movement module 4 to drive the defect application module 8 to move from the lower half circle to the upper half circle of the annular guide rail 2 and perform reverse movement, while the active guide rail 7 in this embodiment is for the horizontal movement module 4 to drive the defect application module 8 to move from the upper half circle to the lower half circle of the annular guide rail 2 and perform reverse movement.

[0111] Specifically, in this embodiment, the active guide rail 7 includes a sliding rod 12 and a counterweight 13. The sliding rod 12 is provided with an auxiliary track groove 12.1 that matches the inner rail 2.2 and the outer rail 2.1 and can cooperate with the auxiliary roller 4.5. The counterweight 13 is fixedly arranged at the end of the sliding rod 12 and is connected to the fourth elastic member 14, and the other end of the fourth elastic member 14 is fixedly arranged on the inner rail 2.2.

[0112] More specifically, in this embodiment, the sliding rod 12 is rotatably arranged on the inner rail 2.2 through a bearing, and in the natural state, as Figure 9As shown, the counterweight 13 droops, causing the other end of the sliding rod 12 to rise. While blocking the track between the inner rail 2.2 and the outer rail 2.1, when the main roller 4.4 has not disengaged from the track groove 2.5, the auxiliary roller 4.5 contacts the auxiliary track groove 12.1 and enters the auxiliary track groove 12.1, and is supported by the movable guide rail 7. When the main roller 4.4 continues to roll, it drives the movable guide rail 7 to rotate, opening the upper half of the track 2.4. At this time, the main roller 4.4 disengages from the track groove 2.5, and the horizontal movement module 4 moves through the roller of the auxiliary roller 4.5 on the auxiliary track groove 12.1. When the horizontal movement module 4 moves, it is equivalent to adding a counterweight behind the sliding rod 12. At this time, the rear end of the sliding rod 12 descends and the counterweight 13 ascends, as Figure 10 shown. A stop block 15 is provided on the outer rail 2.1, which can block and support the sliding rod 12, enabling the horizontal movement module 4 to enter the terminal at the rear end of the outer rail 2.1 under the action of the auxiliary roller 4.5. When the horizontal displacement module enters the terminal at the rear end of the outer rail 2.1, the auxiliary roller 4.5 disengages from the sliding rod 12. Under the action of the counterweight 13 and the fourth elastic member 14, the rear end of the sliding rod 12 rises, opening both the lower half of the track 2.3 and blocking the upper half of the track 2.4, ensuring that the horizontal movement module 4 can enter the lower half of the track 2.3 for movement.

[0113] In summary, the overall solution of the prefabricated defect application device provided by the present invention is as follows: Common ferrosilicon casting pools are strip-shaped. Through on-site investigation, it is found that the temperature change and hardness change can be approximately regarded as linear changes from the head to the tail of the casting pool. Therefore, strip-shaped pressing plates are used to apply prefabricated defects in batches according to the hardness change of high-temperature ferrosilicon.

[0114] Install the defect application module 8 along the ferrosilicon ingot mold, and set the process control for the stroke h of the hydraulic cylinder and the full operation state of the motor 4.1. After ferrosilicon casting, the prefabricated defects can be applied.

[0115] When the high-temperature ferrosilicon is in a semi-solidified state, first, the motor 4.1 drives the main roller 4.4 to drive the equipment to slowly and accurately move along the annular guide rail 2 to the area of the first part where prefabricated defects need to be applied. After reaching the predetermined position, the motor 4.1 pauses and the defect application module 8 stops horizontal movement; then the lifting module 3 is started, and the piston rod of the hydraulic cylinder pushes down the working mechanisms such as the defect application module 8 and the flexible protection device 10 vertically. During the downward pressure, the spindle-shaped indenter 8.1 contacts the high-temperature ferrosilicon, and the reaction force causes the compression spring to absorb kinetic energy and be compressed. As the compression degree of the compression spring increases, the elastic force F also increases, and the spindle-shaped indenter 8.1 continues to press into the ferrosilicon until the hydraulic piston rod reaches the maximum stroke and the elastic force F is balanced with the reaction force of the ferrosilicon on the spindle-shaped indenter 8.1, that is, when the spindle-shaped indenter 8.1 reaches the required depth of prefabricated defect application, the spindle-shaped indenter 8.1 stops pressing down. After maintaining this state for a set period of time, at this time, the high-temperature ferrosilicon in the area where the prefabricated defect is applied has cooled to a certain temperature, and its fluidity has been greatly reduced; then, the piston rod of the hydraulic cylinder of the lifting module 3 is controlled to drive the defect application module 8 to move vertically upward to the initial horizontal position. At this time, a series of hole-shaped prefabricated defects have been applied to the ferrosilicon in this area, and the compression spring has also returned to its natural state. The motor 4.1 is started, and it continues to drive the main roller 4.4 to slowly drive the defect application module 8 to accurately move along the fixed guide rail to the area of the second part where prefabricated defects need to be applied and then pauses the translation. This process is repeated.

[0116] After defects have been applied to all areas of the entire ferrosilicon ingot, the motor 4.1 drives the main roller 4.4 to drive the defect application module 8 to continue moving along the annular guide rail 2. It moves to the end part of the annular guide rail 2 and cooperates with the V-shaped limit groove 6.4 on the sheave 6.3 through the auxiliary roller 4.5. The sheave 6.3 is concentrically fixed with the ratchet 6.1 and locked against relative rotation, enabling the horizontal movement module 4 to start climbing along the guide rail, and at the same time driving the sheave 6.3 of the return mechanism to rotate. When approaching the end inflection point, the front end of the reversing ejector rod 5.3 in the reversing device 5 contacts the reversing baffle 5.1 in front of the annular guide rail 2, and the horizontal movement module 4 is still moving forward. At this time, the reversing push rod 5.4 moves backward relative to the reversing seat 5.2. When the horizontal movement module 4 reaches the frontmost vertex, the push plate 5.7 on the reversing push rod 5.4 in the reversing seat 5.2 just presses down the reversing switch 5.6 of the motor 4.1. Subsequently, the output of the main roller 4.4 and the auxiliary roller 4.5 of the motor 4.1 is reversed, and then drives the equipment to continue climbing obliquely backward and upward under the support of the sheave 6.3 in the return module 6, completing the "V"-shaped ascent. At the same time, the horizontal movement module 4 gradually moves away from the reversing baffle 5.1 in front of the annular guide rail 2, so the reversing push rod 5.4 in the reversing device 5 gradually returns to its natural state under the action of the second elastic member 5.9.The horizontal movement module 4 always moves obliquely backward and upward until it reaches the upper horizontal section of the annular guide rail 2, that is, it enters the upper semi-circular track 2.4. At this time, the auxiliary roller 4.5 is disengaged from the grooved pulley 6.3, and the next notch of the grooved pulley 6.3 is facing the lower track of the annular guide rail 2, facilitating the return process of the main roller 4.4 and the auxiliary roller 4.5 to cooperate with the grooved pulley 6.3 in the next defect application cycle; subsequently, the motor 4.1 pauses and the equipment pauses. After the ferrosilicon ingot is demolded, the motor 4.1 drives the main roller 4.4 to drive the horizontal movement module 4 to quickly move along the upper semi-circular track 2.4 of the annular guide rail 2 to the rear end of the annular track, and then moves obliquely backward and downward along the end section of the rear end of the annular guide rail 2. During the descent, the auxiliary roller 4.5 contacts the movable guide rail 7, and the auxiliary roller 4.5 cooperates with the V-shaped track groove 2.5 on the movable guide rail 7 and presses the movable guide rail 7 down to the depressed state. The stroke is limited by the stop block 15. Then, the auxiliary roller 4.5 drives the horizontal movement module 4 to move smoothly to the rear end of the annular guide rail 2 and disengages from the movable guide rail 7 under the support of the movable guide rail 7; after the pressure of the auxiliary roller 4.5 is removed, the movable guide rail 7 returns to its natural state under the action of the counterweight 13 and the fourth elastic member 14; then, the reversing ejector rod 5.3 in the reversing device 5 contacts the reversing baffle 5.1 at the rear end of the annular guide rail 2. When the horizontal movement module 4 reaches the end point at the rearmost end, the push plate 5.7 on the reversing push rod 5.4 just presses down the forward reversing switch 5.6 to complete the output commutation of the motor 4.1; subsequently, the reversing push rod 5.4 gradually returns to its natural state under the action of the second elastic member 5.9; then, the motor 4.1 drives the main roller 4.4 to drive the horizontal movement module 4 to move obliquely forward and downward to the horizontal section of the lower semi-circular track 2.3 of the annular guide rail 2 for resetting. Thus, the defect application work of one ferrosilicon ingot is completed.

[0117] After waiting for the end of a new round of casting, the motor 4.1 drives the main roller 4.4 to drive the horizontal movement module 4 to start a new round of defect application work.

[0118] Due to the existence of a series of prefabricated defects, the demolded ferrosilicon ingot will have stress concentration during the subsequent machine crushing process, and the concentrated stress will generate cracks along the arrangement of the prefabricated defects. Only a relatively small crushing pressure is required to easily crush the ferrosilicon into the predetermined shape and size, and almost no waste of powder and unqualified products will be generated.

[0119] As can be seen from the above, compared with other equipment, the prefabricated defect application device has the following advantages: 1. Through the horizontal movement module 4, the automatic commutation of the prefabricated defect application module 8, precise positioning on the annular guide rail 2, and rapid movement to the area where defects are applied to the ferrosilicon can be achieved.

[0120] 2. Through the lifting module 3, the horizontal pressing down and upward movement of the defect application module 8 can be achieved without being affected by torsion to ensure good prefabricated defect application effects.

[0121] 3. The defect application module 8 can use a ceramic shuttle-shaped indenter 8.1 that does not react with high-temperature ferrosilicon and a mechanical structure that is convenient for installation and replacement to press defects on the high-temperature ferrosilicon with the shuttle-shaped indenter 8.1.

[0122] 4. The flexible protection device 10 enables the equipment to have a certain self-protection ability. When the hardness of the high-temperature ferrosilicon is relatively high, it can protect the equipment, especially the ceramic shuttle-shaped indenter 8.1, by compressing the spring.

[0123] 5. The return module 6 can achieve the one-way rotation of the sprocket 6.3 through the sprocket 6.3 constrained by the ratchet 6.1, and then support the equipment after the work is completed to achieve a "V"-shaped return movement at the end of the fixed guide rail, leaving enough space for the subsequent demolding of the ferrosilicon ingot.

[0124] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
