Description

Technical Field

[0001] This invention relates to the field of steelmaking equipment technology, and in particular to a drawing device for a continuous casting production line. Background Technology

[0002] In the continuous casting process, the delivery of the dummy ingot is one of the most important steps. The process of delivering the dummy ingot is as follows: before the molten metal enters the crystallizer, the dummy ingot rod assembly is precisely filled into the crystallizer and the bottom opening of the crystallizer is temporarily blocked so that the billet can be guided into the roller group.

[0003] To improve automation, reduce labor intensity, minimize impact on the crystallizer during delivery, extend the crystallizer's service life, and improve feeding accuracy, Chinese invention patent CN115007819B discloses a fully automatic unmanned ingot feeding system and its working method for a slab continuous casting machine. The system utilizes a conveyor belt structure in conjunction with roller sets to support and move the ingot feeding rod assembly. Before filling the crystallizer with the ingot feeding rod assembly, a vertically placed hard plate is inserted into the crystallizer as a protective plate to prevent impact and friction on the crystallizer during the filling process, thereby reducing damage to the crystallizer. Multiple sensors and a rangefinder are used to monitor the real-time position and status of the ingot feeding rod assembly, achieving automated ingot delivery.

[0004] While the aforementioned disclosed technical solutions can achieve automated delivery and effectively reduce damage to the crystallizer, the following problems still exist:

[0005] Firstly, because the derrick assembly needs to smoothly enter the crystallizer and be delivered to the bottom of the crystallizer, the space available for the liner plate is relatively limited. If the liner plate is designed to be too thick, it will affect the smooth delivery of the derrick assembly. If it is designed to be too thin, it will result in poor protection and easy deformation after use. When inserting the liner plate, it is also easy to damage the crystallizer during the insertion process due to misalignment of the liner plate or deformation of the liner plate during use.

[0006] Secondly, after the siphon rod assembly detaches from the conveyor belt structure and roller group that support it, the position near the top is in a suspended state with less restraint. During the movement of the siphon rod assembly in the crystallizer, the lack of restraint at the top (the end with the siphon block) makes it difficult to control its posture, which in turn makes it easy for the top to cause a large impact on the guard plate and the crystallizer.

[0007] Therefore, there is a need for a continuous casting production line ingot dredging device that is not easily damaged, reliable and durable, easy to use, and causes minimal damage to the crystallizer during use. Summary of the Invention

[0008] This application provides a dart device for a continuous casting production line, which solves the technical problems in the prior art where dart devices for continuous casting production lines are easily damaged by impact, the attitude of the dart rod assembly is difficult to control, and the crystallizer is easily damaged during use; it achieves the technical effects of a dart device for continuous casting production lines that is not easily damaged, reliable and durable, easy to use, and causes less damage to the crystallizer during use.

[0066] Example 1

[0067] like Figures 1 to 3As shown, the dummy bar device for the continuous casting production line of this application is used to feed the dummy bar assembly it carries into the crystallizer 001 and to a predetermined position. It is used in conjunction with the guide roller group 002 located at the bottom of the crystallizer 001 and used to guide the dummy bar assembly and the billet to move as needed. It is also used in conjunction with the dummy bar lifting device 003 used to lift the dummy bar assembly after billet removal onto the dummy bar device. The dummy bar assembly, the crystallizer 001, the guide roller group 002 and the dummy bar lifting device 003 are all prior art and will not be described in detail here.

[0068] The ingot derrick device for continuous casting production line of this application includes a bottom carrier 100, a transverse carrier 200, an intermediate conveyor assembly, a side roller assembly 400, an end guard plate assembly, a protective belt assembly, an auxiliary belt assembly, a power assembly, and a control unit.

[0069] The base carrier 100 is placed or fixed on the ground and is a combination of multiple wheels or a horizontally placed, strip-shaped rigid plate, which serves as a load-bearing and supporting element.

[0070] The transverse carrier 200 is a horizontally placed, strip-shaped rigid plate positioned on the base carrier 100. Under the coordinated control of the power component and the control unit, it moves relative to the ground along its own length direction, thereby moving closer to or further away from the crystallizer 001 as needed, and is used to support other components of the ingot derrick device for the continuous casting production line.

[0071] like Figure 4 As shown, the intermediate conveying assembly is a horizontally positioned conveyor belt structure, located at the top of the transverse carrier 200, with its length direction being the same as that of the transverse carrier 200 and its length being greater than that of the transverse carrier 200; both ends of the transverse carrier 200 are located directly below the intermediate conveying assembly.

[0072] The intermediate conveyor assembly has a hook rod assembly 331 for hooking the hanging rod 830 of the guide rod assembly, an adsorption plate 332 for adsorbing and fixing the guide head 810, and a positioning rod 333 for fixing the auxiliary belt assembly.

[0073] The hook rod assembly 331 is an electric hook that is controlled to hook the hanging rod 830 or move away from the hanging rod 830 (release from the hanging rod 830) as appropriate; the distance between the hook rod assembly 331 and the adsorption plate 332 is similar to the length of the guide rod assembly, with a difference of no more than 5 cm.

[0074] The adsorption plate 332 is a ferromagnetic plate.

[0075] The positioning rod 333 is a rigid rod, and its length direction is the same as the width direction of the belt of the intermediate conveying assembly.

[0076] The width of the intermediate conveying component is less than or equal to one-third of the width of the transverse carrier 200.

[0077] The side roller group 400 consists of two rows of rigid rollers mounted on both sides of the intermediate conveying assembly via rigid supports. These rollers support the derrick assembly, preventing the derrick assembly, which is moved by the intermediate conveying assembly, from placing its entire weight on the intermediate conveying assembly, thus extending its service life. The axial direction of the rollers in the side roller group 400 is the same as the width direction of the intermediate conveying assembly. The spacing between the rollers in the side roller group 400 is less than 20 cm. The top of the rollers in the side roller group 400 is at the same height as the top surface of the belt of the intermediate conveying assembly. After the derrick assembly is placed on the intermediate conveying assembly, it also contacts both rows of rollers.

[0078] like Figure 5 and Figure 6 As shown, the dummy bar assembly includes a dummy bar head 810, a chain 820, and a hanging rod 830. The dummy bar head 810 and the hanging rod 830 are respectively positioned at both ends of the chain 820. The dummy bar head 810 is made of ferromagnetic material. The hanging rod 830 is matched with the hook rod assembly 331. The dummy bar assembly is used to fill the crystallizer 001 in a timely manner and guide the movement of the billet. This is existing technology and will not be described in detail here.

[0079] like Figure 2 and Figure 8 As shown, the end guard assembly is fixed to the end of the transverse carrier 200 near the crystallizer 001, and is used to restrict the movement of the siphon rod assembly and support the auxiliary belt assembly.

[0080] The end guard assembly includes an end guard 510 and a connecting frame 520 for supporting and fixing the end guard 510;

[0081] The end guard plate 510 is a rigid plate that is vertically or inclined. It is located at the end near the intermediate conveying component and the distance between it and the intermediate conveying component is 35 to 60 cm. The angle between it and the intermediate conveying component is 90 to 110 degrees. The bottom surface is higher than the crystallizer 001 and the top surface is higher than the intermediate conveying component. The connecting frame 520 is a rigid support that fixes the end guard plate 510 on the transverse carrier 200.

[0082] The protective belt assembly is used to arrange a belt that acts as a buffer at a position close to the inner wall of the crystallizer 001. The main body is a horizontally placed roll with the belt wound on it. There are two rolls, which are respectively positioned at the end of the transverse carrier 200 near the crystallizer 001 and the top of the end guard plate assembly.

[0083] The protective belt assembly includes a protective belt, a support drum 620, a drum carrier 630, and a pump assembly 640 that communicates with the protective belt and is used to control the expansion and contraction of the protective belt.

[0084] One end of the protective strip is wrapped and positioned on the load-bearing drum 620;

[0085] The protective strip includes a base strip 611 and a cover strip 612; the base strip 611 is a rubber strip; the cover strip 612 is a flexible metal strip, both its length and width being smaller than the base strip 611; the edge of the cover strip 612 is fixed to one side of the base strip 611, and the distance between the edge of the cover strip 612 and the edge of the base strip 611 is 3 to 10 centimeters; the cover strip 612 and the base strip 611 form a strip-shaped enclosed space;

[0086] The bearing drum 620 is a horizontally placed rigid drum with the same axial direction as the width direction of the transverse carrier 200. Both are positioned on the drum carrier 630 and rotate under the coordinated control of the power component and the control unit, thereby timely winding and releasing the protective belt.

[0087] The roll carrier 630 is a rigid frame, and there are two of them, which are respectively fixed to the top of the end guard plate assembly and the end of the intermediate conveying assembly near the crystallizer 001.

[0088] The air pump assembly 640 is a combination of an air pump, an air valve and an air delivery pipe, which operates under control and is connected to the internal space of the protective belt.

[0089] Before inserting the ingot rod assembly into the crystallizer 001, first control the operation of the two protective belt assemblies to release the protective belts, so that the protective belts enter the crystallizer 001 and the bottom of the protective belts is close to the bottom opening of the crystallizer 001. Then control the protective belts to inflate and improve their buffering and protective effects. After the protective belts are in place, the base 611 of the protective belts faces the inner wall of the crystallizer 001. After the ingot rod assembly is in place, control the protective belt assembly to reset.

[0090] like Figure 2 , Figures 7 to 10 As shown, the auxiliary belt assembly is a strip in shape, with one end fixed to the positioning rod 333. Under normal conditions, it is close to the belt of the intermediate conveying assembly, and the other end is magnetically attached to the ingot head 810 as needed. After the ingot rod assembly is separated from the intermediate conveying assembly, the auxiliary belt assembly suspends the ingot rod assembly and gradually enters the crystallizer 001 and moves to the predetermined position.

[0091] The power assembly is used to provide power for the operation of each component of the dummy ingot device for the continuous casting production line of this application, and the control unit plays the role of controlling the coordinated operation of each component of the dummy ingot device for the continuous casting production line. Both of these are existing technologies and will not be described in detail here.

[0092] The control unit includes a dummy bar tracking system; the dummy bar tracking system includes multiple sensors and multiple limit switches, which is essentially a signaling system, a prior art technology, that tracks the entire process from inserting the dummy bar assembly, starting casting, to the return of the dummy bar assembly, and sends out arrival signals at each point to make each component operate according to a predetermined program; the structure of the dummy bar tracking system can be referred to the fully automatic unmanned dummy bar feeding system and its working method disclosed in Chinese Invention Patent No. CN115007819B.

[0093] Preferably, the bottom carrier 100 consists of multiple wheels positioned at the bottom of the transverse carrier 200, which rotate in a controlled manner to drive the transverse carrier 200 to move laterally as needed.

[0094] Preferably, the base carrier 100 is a horizontally placed, strip-shaped rigid plate; the transverse carrier 200 has the same length direction as the base carrier 100 and is controlled to slide along the length direction of the base carrier 100.

[0095] Furthermore, such as Figure 5 As shown, the intermediate conveying assembly includes a carrier frame 310, carrier pulleys 320, and a conveyor belt 330. The carrier frame 310 is a rigid frame, fixed to the top of the transverse carrier 200, and there are two of them, located near the end of the transverse carrier 200. The carrier pulleys 320 are horizontally placed rigid wheels with an "I"-shaped cross-section, and there are two of them, located near the end of the transverse carrier 200. They are rotatably connected to the carrier frame 310 around their own axes and rotate under the coordinated control of the power assembly and the control unit. The conveyor belt 330 is an annular belt, fitted onto the two carrier pulleys 320, and is stretched into an elongated shape by the two carrier pulleys 320 and always kept taut. The conveyor belt 330 is the belt body of the aforementioned intermediate conveying assembly. The hook rod assembly 331, the suction plate 332, and the positioning rod 333 are all fixed on the conveyor belt 330.

[0096] Furthermore, such as Figure 1 As shown, the transverse carrier 200 also has a centering component directly or indirectly positioned to correct the movement direction of the derrick assembly. The main body of the centering component is a telescopic cylinder. The position of the derrick assembly is corrected by pushing the derrick assembly from both sides. This is existing technology and will not be described in detail here.

[0097] Furthermore, such as Figure 4 As shown, the auxiliary belt assembly includes an auxiliary belt 710 and an end positioning body 720; the auxiliary belt 710 is a metal or non-metal soft belt, which is a non-elastic belt, and one end is fixed to the positioning rod 333; the end positioning body 720 is a rigid block and has a built-in electromagnet or is an electromagnet block as a whole, which matches the surface of the spindle head 810 away from the chain 820, and controls the adsorption and fixation of the spindle head 810.

[0098] Furthermore, the end positioning body 720 is an electromagnet block; the contact area between the end positioning body 720 and the adsorption plate 332 is less than one-third of the contact area between the end positioning body 720 and the ingot head 810, and the attraction between the end positioning body 720 and the ingot head 810 is relatively large; the attraction between the end positioning body 720 and the adsorption plate 332 is relatively small, only greater than the weight of the end positioning body 720; the end positioning body 720 is independently connected to the power supply through a power line.

[0099] Preferably, when the end positioning body 720 adsorbs the spindle head 810 and moves between the two protective belts, the protective belts are controlled to expand and squeeze the end positioning body 720 and the spindle head 810 from the periphery, so that the two fit more tightly, avoid misalignment, and further ensure the positional accuracy of the spindle head 810 when it is lowered to the predetermined position.

[0100] In the continuous casting process, when it is necessary to feed the dummy ingot: First, control the transverse carrier 200 to move the dummy ingot rod assembly, so that the space between the intermediate conveying assembly and the end guard plate assembly moves to directly above the crystallizer 001; at this time, the hook rod assembly 331 hooks the hanging rod 830, the auxiliary belt 710 is close to the conveyor belt body 330, the end positioning body 720 is in the energized state, and the end positioning body 720 is adsorbed and fixed on the adsorption plate 332 and adsorbs the end of the dummy ingot head 810 away from the chain 820;

[0101] Then, the protective belt assembly is controlled to operate within the crystallizer 001 to deploy a protective belt that provides protection.

[0102] Subsequently, the conveyor belt 330 is rotated to gradually feed the ingot rod assembly into the crystallizer 001;

[0103] After the siphon rod assembly is completely detached from the conveyor belt 330, the end positioning body 720 also detaches from the adsorption plate 332; the conveyor belt 330 continues to rotate, and the auxiliary belt assembly gradually sends the siphon rod assembly to the set target position. The guide roller group 002 clamps and positions the siphon rod assembly and controls the end positioning body 720 to be de-energized.

[0104] Casting is then carried out, and the ingot recovery process begins. Before entering the ingot recovery process, the protective belt assembly, intermediate conveyor assembly, and auxiliary belt assembly are reset. The conveyor belt 330 is rotated so that the adsorption plate 332 moves to the bottom of the intermediate conveyor assembly (the end positioning body 720 needs to be kept energized when it is located at the bottom of the conveyor belt 330) and the hook rod assembly 331 moves to the end of the intermediate conveyor assembly away from the crystallizer 001.

[0105] Entering the ingot recovery stage: After the billet is output from the crystallizer 001, the ingot rod assembly is lifted by the ingot rod lifting device 003 (the billet removal is completed at the same time or before this); the transverse carrier 200 is controlled to move away from the crystallizer 001, and the hanging rod 830 of the ingot rod assembly is hooked by the ingot rod lifting device 003. The ingot rod assembly is controlled to detach from the ingot rod lifting device 003, and the ingot rod assembly is dragged to the top of the intermediate conveying assembly by the hook rod assembly 331; ready to enter the next operation cycle.

[0106] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0107] This invention solves the technical problems in existing technologies, such as the susceptor device in continuous casting production lines being easily damaged by impact, the difficulty in controlling the posture of the susceptor rod assembly, and the easy damage to the crystallizer during use. It achieves the technical effects of the susceptor device in continuous casting production lines being less prone to damage, reliable and durable, easy to use, and causing less damage to the crystallizer during use.

[0108] Example 2

[0109] To further improve the reliability of the ingot derrick device used in the continuous casting production line of this application, and to ensure the firmness and accuracy of the adsorption and fixation between the end positioning body 720 and the ingot head 810 without frequent manual cleaning, this embodiment of the application optimizes and improves the structure of the auxiliary belt assembly based on the above embodiment, and adds a care component to automatically clean the ferromagnetic debris such as iron filings adhering to the ingot head 810 and the end positioning body 720 using magnetic force; specifically:

[0110] When the siphon rod assembly is completely above the intermediate conveying assembly, the distance between the adsorption plate 332 and the siphon head 810 is greater than 5 cm.

[0111] like Figures 11 to 14 As shown, the auxiliary belt assembly also includes a connecting belt assembly; the connecting belt assembly is located between the auxiliary belt 710 and the end positioning body 720, connecting and fixing the two together;

[0112] The connecting strip assembly includes a carrier rod 731, a basic connecting strip 732, and an elastic connecting strip 733;

[0113] The carrier rod 731 is a horizontally placed rigid rod, fixed to the end of the auxiliary belt 710 away from the positioning rod 333, and its axial direction is the same as the width direction of the auxiliary belt 710.

[0114] The basic connecting strip 732 is a non-elastic strip with a length of 15 to 30 centimeters. One end is fixed to the carrier rod 731, and the other end is fixed to the end positioning body 720.

[0115] The elastic connection belt 733 is an elastic belt body, with one end fixed to the carrier rod body 731 and the other end fixed to the end positioning body 720. When the elastic connection belt 733 is not stretched, its length is 0.5 to 0.7 times the length of the basic connection belt 732. When the end positioning body 720 is not adsorbed and fixed to the dummy bar head 810, it is in a bent state. When the end positioning body 720 is adsorbed and fixed to the dummy bar head 810, it is in a straightened state.

[0116] The nursing component is used to clean ferromagnetic material debris adhered to the dummy bar head 810 and the end positioning body 720 by magnetic force, and includes a carrier frame 910, a vertical plate 920, and a plate displacement component 930 for driving the vertical plate 920 to move up and down. The nursing component is located at the top near the middle of the middle conveying component.

[0117] The carrier frame 910 is a "C"-shaped rigid plate body with an open bottom, and its end is fixed to the transverse moving carrier 200, buckling the middle conveying component and the side roller group 400.

[0118] The top of the carrier frame 910 is provided with a long strip-shaped through groove for the vertical plate 920 to pass through.

[0119] The vertical plate 920 is a vertically placed rectangular rigid plate body, passing through the carrier frame 910, with an electromagnet built-in or the whole being a rectangular plate-shaped electromagnet, and is controlled to be powered on and off.

[0120] The plate displacement component 930 is a vertically placed telescopic rod structure, with one end fixed to the carrier frame 910 and the other end fixed to the side wall of the vertical plate 920, and is controlled to expand and contract to drive the vertical plate 920 to rise and fall.

[0121] When the vertical plate 920 is in the raised state, the space enclosed by the carrier frame 910 and the middle conveying component is available for the dummy bar component to pass through. When the vertical plate 920 moves down, it can be inserted into the gap between the end positioning body 720 and the dummy bar head 810.

[0122] The end positioning body 720 is a rigid block body and has two built-in electromagnets, and the two electromagnets can be independently controlled. One of the two electromagnets is located inside the end positioning body 720 near the adsorption plate 332 and is used in cooperation with the adsorption plate 332. The other one is located at the position of the end positioning body 720 far from the auxiliary belt 710 (near the dummy bar head 810) and is used in cooperation with the dummy bar head 810.

[0123] During operation: After the billet is output from the crystallizer 001, the dummy bar assembly is lifted by the dummy bar lifting device 003; the transverse carrier 200 is controlled to move away from the crystallizer 001, and the hanging rod 830 of the dummy bar assembly is hooked by the dummy bar lifting device 003. The dummy bar assembly is then controlled to detach from the dummy bar lifting device 003, and the dummy bar assembly is dragged to directly above the intermediate conveying assembly by the hook rod assembly 331; at this time, the end positioning body 720 is only close to the electromagnetic field of the adsorption plate 332. When the iron is energized, it is magnetically attracted and fixed to the adsorption plate 332. The base connecting belt 732 is in a bent state, and there is a gap between the end positioning body 720 and the spindle head 810, allowing the vertical plate 920 to be inserted. When the gap between the end positioning body 720 and the spindle head 810 moves to directly below the vertical plate 920, the control conveyor belt 330 stops rotating. The electromagnet inside the control end positioning body 720 is de-energized, and the vertical plate 920 is inserted into the gap between the end positioning body 720 and the spindle head 810. The gap between them is then filled, and the vertical plate 920 is energized. At this time, the ferromagnetic debris is attracted to the vertical plate 920. The vertical plate 920 is moved upward and reset, and the magnet in the end positioning body 720 near the adsorption plate 332 is energized. At the same time, the conveyor belt 330 continues to rotate (due to the limitation of the carrier 310 and the influence of the electromagnet in the end positioning body 720, the end positioning body 720 will not be attracted by the vertical plate 920 and its movement will be restricted). When the end positioning body 720 moves away from the vertical plate 920... After the nursing component is in place, the electromagnet near the spindle head 810 inside the control end positioning body 720 is energized, while the other electromagnet is de-energized. The end positioning body 720 overcomes the elasticity of the elastic connecting belt 733 and is fixed to the spindle head 810, while simultaneously straightening the base connecting belt 732; preparing for the next work cycle; after the spindle rod assembly moves away from the nursing component as a whole, the control vertical plate 920 is de-energized to unload the debris (the debris then detaches from the conveyor belt 330 as it moves).

[0124] Preferred, such as Figure 14 As shown, the bottom of the carrier frame 910 is provided with a liquid spraying cleaning assembly 940 and / or an air spraying assembly 950; the liquid spraying cleaning assembly 940 and the air spraying assembly 950 spray water and / or air towards the derrick assembly, auxiliary belt assembly, intermediate conveyor assembly and side roller group 400 for cleaning; the liquid spraying cleaning assembly 940 is a combination of a liquid nozzle, a liquid pump and a water source; the air spraying assembly 950 is a combination of a gas nozzle and an air pump.

[0125] Preferably, the gas ejected by the jet assembly 950 is hot gas, which serves a drying function.

[0126] Preferred, such as Figure 15 As shown, the transverse carrier 200 is also provided with a bottom brush 960; the bottom brush 960 is a horizontally placed strip-shaped brush, which brushes away the debris adhering to the conveyor belt 330 when it is running.

[0127] Preferably, the bottom brush 960 is equipped with a gas nozzle connected to an air pump, which blows air to clean the brushed parts during brushing.

[0128] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
