Description

Technical Field

[0001] This invention belongs to the field of continuous casting machine technology, and particularly relates to a device and method for separating residual slag steel in continuous casting machines. Background Technology

[0002] Ladle residue in continuous casting machines is a mixture of molten steel and slag retained at the end of casting to prevent slag from being drawn into the tundish and to ensure the quality of the cast billet. It mainly consists of residual molten steel and refining reducing slag, and its generation is influenced by multiple factors, including process control, equipment characteristics, molten steel properties, and operator skill. The generation of ladle residue reduces steel yield and increases production costs. The refining reducing slag is difficult to handle and pollutes the environment. However, its recycling can achieve resource recycling, reduce energy consumption, and reduce pollution, offering both economic and environmental benefits. It is a key link in the green and efficient development of steel production. Currently, the industry has developed various traditional methods for handling ladle residue, but all have various shortcomings and have failed to achieve efficient, low-cost, and low-pollution recycling.

[0003] Existing methods for handling ladle residue have many shortcomings and cannot meet production needs. The ladle recycling method, currently widely used, involves pouring the remaining molten steel and slag into a ladle containing a certain amount of high-temperature molten iron after casting and mixing. This method is prone to slag crusting and sticking to the ladle due to insufficient molten iron or low temperature. The empty ladle recycling method involves directly pouring the residue into an empty ladle after steel tapping. This method is prone to slag overflow and foaming, damaging the equipment. Furthermore, most existing methods require additional cutting and processing steps, increasing cutting costs and labor intensity, and generating smoke pollution and scrap steel burning. They cannot achieve efficient natural separation and clean recycling of ladle residue. Therefore, there is an urgent need for a device and method for separating slag and steel residue from ladle residue in continuous casting machines. Summary of the Invention

[0004] To address some or all of the technical problems existing in the prior art, the present invention provides a device and method for separating residual slag steel from a continuous casting machine.

[0005] In one aspect of the present invention, a slag steel separation device for a continuous casting machine is provided. The slag steel separation device is disposed on one side of the slag yard, and a hoisting device is disposed above the slag steel separation device. The slag steel separation device includes a circular track disposed on one side of the slag yard, a separation platform disposed on one side of the circular track, a storage tank disposed above the circular track, a drive vehicle slidably connected to the circular track, and multiple tank cars, wherein: The driving vehicle is connected to the tanker truck, and multiple tanker trucks are interconnected. Each tanker truck includes a vehicle body, which is slidably connected to the circular track via wheels. Supports are vertically connected to the top of both sides of the vehicle body, and slots are provided on the top of the supports. A separation tank is provided between two supports. The top of the separation tank is symmetrically provided with two lifting trunnions along the radial direction. The lifting trunnions are engaged in the slots. The bottom of the separation tank has a circular hole, and a separation assembly is provided in the circular hole. The separation assembly includes a connecting post slidably connected to the circular hole, a top plate provided at the top of the connecting post, and a pad provided at the bottom of the connecting post. The outer diameter of the top plate matches the inner diameter of the separation tank. The inner wall of the separation tank is sprayed with an anti-stick coating. There is a preset distance between the bottom of the separation tank and the top of the vehicle body. The storage tank has a drain outlet at the bottom, and a sealing switch is installed inside the drain outlet. The continuous casting machine is equipped with a control module, which is electrically connected to the drive vehicle, the sealing switch, and the hoisting equipment.

[0006] Furthermore, in the above-mentioned continuous casting machine's slag steel separation device, a first support plate is provided at both ends of the vehicle body, and a first fixing hole is opened on the first support plate. Two adjacent tank cars are connected by fasteners that cooperate with the two first fixing holes.

[0007] Furthermore, in the above-mentioned slag steel separation device of the continuous casting machine, a second support plate is provided at one end of the drive vehicle, and a second fixing hole is provided on the second support plate. The drive vehicle and the tank car are connected by fasteners that fit the first fixing hole and the second fixing hole.

[0008] Furthermore, in the above-mentioned slag steel separation device for continuous casting machine, the number of tank cars is 3 to 6.

[0009] Furthermore, in the above-mentioned continuous casting machine's slag steel separation device, the sealing switch is a stopper rod with an outer diameter matching the inner diameter of the drain outlet.

[0010] Furthermore, in the above-mentioned slag steel separation device for continuous casting machine, the storage tank is an tundish.

[0011] In another aspect of the present invention, the method for separating residual slag steel in a continuous casting machine provided by the present invention includes: Step 1: After the ladle is poured on the continuous casting machine, it is hoisted to the top of the storage tank by the hoisting equipment. Then, the liquid slag steel in the ladle is poured into the storage tank. The inner wall of the separation tank to be filled is sprayed with the anti-stick coating in advance. Step 2: The drive vehicle moves the tanker along the circular track and passes under the storage tank. When the first separation tank behind the drive vehicle moves to the bottom of the storage tank, the control module controls the drive vehicle to stop moving and simultaneously controls the sealing switch to the open state. The liquid casting residue steel flows into the first separation tank through the drain. At this time, under the action of gravity, the bottom end of the top plate in the separation assembly is attached to the bottom end of the inner wall of the separation tank. Step 3: When the liquid level of the molten cast slag steel in the first separation tank reaches the preset height, the control module controls the drive vehicle to continue moving and simultaneously controls the sealing switch to the closed state. When the second separation tank moves to below the storage tank, the control module controls the drive vehicle to stop moving and simultaneously controls the sealing switch to the open state. The molten cast slag steel flows into the second separation tank through the drain. This process is repeated for the remaining separation tanks until all separation tanks are filled. Step 4: Start the drive vehicle and transport the multiple separation tanks containing the liquid casting slag steel to the separation platform. During operation, the liquid casting slag steel slowly cools and solidifies into solid casting slag steel as the temperature decreases. The separation tanks containing the solid casting slag steel are then lifted onto the separation platform by the hoisting equipment. During this process, the hoisting trunnion disengages from the slot. Step 5: Place the separation tank on the top of the separation platform. At this time, the bottom end of the pad plate will first contact the top of the separation platform. Under the action of the gravity of the separation tank, the connecting column will drive the top plate to move upward relative to each other until the top end of the pad plate is attached to the bottom of the separation tank. The top plate will push the solid casting residue steel upward and separate it from the inner wall of the separation tank, thus realizing the initial separation of the solid casting residue steel. Step 6: Using the hoisting equipment, the separation tank, which has already been initially separated from the solid casting residue steel, is continued to be hoisted to the slag yard. The solid casting residue steel in the separation tank is poured out, and then the empty separation tank is placed on top of the vehicle body, so that the hoisting trunnion is engaged in the slot. The anti-stick coating is then re-sprayed onto the inner wall of the separation tank to be filled. Then, steps 1 to 5 above are repeated.

[0012] The slag separation device and method for continuous casting machines of the present invention have the following advantages and positive effects: (1) This invention temporarily stores liquid casting residue steel in a storage tank and then fills it into a separation tank in an orderly manner, avoiding the overflow and foaming of slag and equipment damage caused by directly pouring casting residue into an empty ladle in the empty ladle recycling method. At the same time, the inner wall of the separation tank is sprayed with anti-stick coating, which avoids the problem of casting residue crusting and sticking to the ladle in the molten iron ladle recycling method, extends the service life of the equipment, reduces the equipment maintenance cost, and achieves efficient and natural separation of solid casting residue steel from the separation tank through the cooperation of the separation components and the anti-stick coating. No additional cutting and processing steps are required, reducing scrap steel burning loss and smoke pollution, greatly improving the metal recovery rate and reducing resource waste. (2) In this invention, the entire device is automatically controlled by the control module. The drive vehicle, sealing switch and hoisting equipment are all controlled by the control module. No manual operation is required, which reduces the labor intensity of the operators. At the same time, the separation tank can be recycled, which reduces waste generation and environmental burden. Multiple tank cars and separation tanks are set up. The storage tank continuously receives the ladle casting residue. Multiple separation tanks are filled, transferred, separated and reset in sequence, realizing the continuous treatment of casting residue slag steel, greatly improving the processing efficiency and adapting to the continuous needs of continuous casting production.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0016] This invention provides a device and method for separating residual slag from steel in a continuous casting machine, such as... Figures 1 to 5 As shown, the slag steel separation device is located on one side of the slag yard 6. A hoisting device is installed above the slag steel separation device. The slag steel separation device includes a circular track 1 located on one side of the slag yard 6, a separation platform 2 located on one side of the circular track 1, a storage tank 3 located above the circular track 1, a drive vehicle 4 slidably connected to the circular track 1, and multiple tank cars 5, wherein: The drive vehicle 4 is connected to the tank car 5. Multiple tank cars 5 are interconnected to achieve synchronous movement and cyclic transfer. The number of tank cars 5 can be flexibly adjusted according to the processing volume to meet the needs of continuous processing. The tank car 5 includes a car body 51, which is slidably connected to the circular track 1 through wheels 52 to ensure that the tank car 5 moves smoothly along the circular track 1 and facilitates reciprocating transfer between the storage tank 3 and the separation platform 2. The top of both sides of the car body 51 is vertically connected to the support 53. The top of the support 53 is provided with a slot 54. The slot 54 is used to limit and fix the separation tank 8 to prevent the separation tank 8 from shifting or tipping during the transfer process, ensuring the safety and stability of the transfer process. The separation tank 8 is set between the two supports 53. Two lifting trunnions 81 are symmetrically arranged radially on the top of the separation tank 8. The lifting trunnions 81 are locked in the slots 54 to realize the detachable connection between the separation tank 8 and the tank car 5. This facilitates the stable placement of the separation tank 8 on the tank car 5 and the subsequent lifting of the separation tank 8 to the separation platform 2 or slag yard 6 by lifting equipment. A circular hole is opened at the bottom of the separation tank 8. A separation component is installed in the circular hole. The separation component includes a connecting column 91 slidably connected to the circular hole, a top plate 92 set at the top of the connecting column 91, and a pad plate 93 set at the bottom of the connecting column 91. The outer diameter of the top plate 92 matches the inner diameter of the separation tank 8 to ensure that the top plate 92 can fit tightly against the inner wall of the separation tank 8. The inner wall of the separation tank 8 is sprayed with an anti-stick coating. The anti-stick coating can effectively prevent the solidified slag steel from sticking to the inner wall of the separation tank 8, reduce the separation difficulty, and reduce tank wear and slag steel loss. There is a preset distance between the bottom of the separation tank 8 and the top of the vehicle body 51. Storage tank 3 is fixedly installed above the circular track 1, and its position corresponds to the transfer path of the circular track 1, ensuring that the tank car 5 can move to the bottom of storage tank 3 for filling operations. Storage tank 3 is used to temporarily store the liquid casting residue steel 7 poured in after the ladle casting is completed, realizing the buffering and temporary storage of casting residue steel 7, which facilitates the orderly filling of multiple separation tanks 8 in the future and ensures continuous processing. The bottom of storage tank 3 is provided with a drain outlet, the size of which is adapted to the outflow speed of liquid casting residue steel 7. A sealing switch 31 is installed in the drain outlet. By opening and closing the sealing switch 31, the outflow and stop of liquid casting residue steel 7 are precisely controlled, realizing quantitative filling of separation tank 8 and avoiding leakage. The continuous casting machine is equipped with a control module, which is electrically connected to the drive car 4, the sealing switch 31, and the hoisting equipment.

[0017] As a specific implementation, in the slag steel separation device of the continuous casting machine of the present invention, the two ends of the car body 51 are respectively provided with a first support plate 55, and the first support plate 55 is provided with a first fixing hole. Two adjacent tank cars 5 are connected by fasteners in conjunction with the two first fixing holes, so as to realize the firm connection of multiple tank cars 5, and ensure that multiple tank cars 5 can move synchronously and smoothly under the drive of the drive vehicle 4, and avoid the tank cars 5 from loosening or shifting during the transfer process.

[0018] In one specific embodiment, in the slag steel separation device of the continuous casting machine of the present invention, a second support plate is provided at one end of the drive vehicle 4, and a second fixing hole is provided on the second support plate. The drive vehicle 4 and the tank car 5 are connected by fasteners that cooperate with the first fixing hole and the second fixing hole, so as to realize the detachable connection between the drive vehicle 4 and the tank car 5, which facilitates the maintenance and replacement of the drive vehicle 4, and also facilitates the adjustment of the connection method of the drive vehicle 4 according to the number of tank cars 5.

[0019] In one specific embodiment, in the slag steel separation device of the continuous casting machine of the present invention, the number of tank cars 5 is 3 to 6, more specifically, the number of tank cars 5 is 4. Of course, the actual number of tank cars 5 is set according to the specific working conditions such as the length of the circular track 1 and the size of the separation tank 8.

[0020] As a specific implementation, in the slag steel separation device of the continuous casting machine of the present invention, the sealing switch 31 is a stopper rod with an outer diameter matching the inner diameter of the drain outlet. With this configuration, the drain outlet is opened and closed by the up and down movement of the stopper rod, which has good sealing performance, can accurately control the outflow of liquid slag steel 7, avoid waste, has a simple structure, good sealing performance, can accurately control the opening and closing of the drain outlet, effectively prevents leakage of liquid slag steel 7, and is easy to maintain and replace.

[0021] As a specific implementation, in the slag steel separation device of the continuous casting machine of the present invention, the storage tank 3 is an intermediate ladle. More specifically, the storage tank 3 can be a waste intermediate ladle, which not only has good high temperature resistance and capacity adaptability, but also can stably store high temperature liquid slag steel 7. In addition, it can be sourced locally to realize waste utilization and reduce production costs.

[0022] On the other hand, the method for separating residual slag steel in continuous casting machines according to the present invention is implemented using the above-mentioned residual slag steel separation device, and specifically includes the following steps: Step 1: After the ladle is poured in the continuous casting machine, it is hoisted to the storage tank 3 by hoisting equipment. Then, the liquid slag steel 7 in the ladle is poured into the storage tank 3 to temporarily store the slag steel 7. The inner wall of the separation tank 8 to be filled is sprayed with anti-stick coating in advance to ensure the anti-stick effect and prevent the subsequent solidified slag steel from sticking to the inner wall of the tank. After the spraying is completed, the separation tank 8 is placed on the support 53 of the tank car 5, so that the hoisting trunnion 81 is locked in the slot 54 to complete the pretreatment of the separation tank 8. Step 2: The drive vehicle 4 drives the tanker 5 to move along the circular track 1 and pass under the storage tank 3. When the first separation tank 8 behind the drive vehicle 4 moves to the bottom of the storage tank 3, the control module controls the drive vehicle 4 to stop moving and simultaneously controls the sealing switch 31 to switch to the open state. The liquid cast slag steel 7 flows into the first separation tank 8 through the drain. At this time, under the action of gravity, the bottom end of the top plate 92 in the separation component is attached to the bottom end of the inner wall of the separation tank 8, sealing the round hole at the bottom of the separation tank 8 to prevent the liquid cast slag steel 7 from leaking from the round hole. Step 3: When the liquid level of the molten cast slag steel 7 in the first separation tank 8 reaches the preset height, the control module controls the drive vehicle 4 to continue moving and simultaneously controls the sealing switch 31 to the closed state. When the second separation tank 8 moves to below the storage tank 3, the control module controls the drive vehicle 4 to stop moving and simultaneously controls the sealing switch 31 to the open state. The molten cast slag steel 7 flows into the second separation tank 8 through the drain. This process is repeated for the remaining separation tanks 8 until all separation tanks 8 are filled, thus achieving orderly and batch filling of multiple separation tanks 8 and ensuring continuous processing efficiency. Step 4: Start the drive vehicle 4 and transport multiple separation tanks 8 containing liquid casting residue steel 7 to the separation platform 2. During operation, the liquid casting residue steel 7 slowly cools and solidifies into solid casting residue steel 7 as the temperature decreases. The separation tanks 8 containing solid casting residue steel 7 are lifted to the top of the separation platform 2 by the hoisting equipment. During this process, the hoisting trunnion 81 disengages from the slot 54 to separate the separation tanks 8 from the tank truck 5. Step 5: Place the separation tank 8 on top of the separation platform 2. At this time, the bottom end of the pad 93 will first contact the top end of the separation platform 2. Under the action of the gravity of the separation tank 8, the connecting column 91 will drive the top plate 92 to move upward relative to each other until the top end of the pad 93 is attached to the bottom of the separation tank 8. The top plate 92 will push the solid casting residue steel 7 upward and separate it from the inner wall of the separation tank 8, thus achieving the initial separation of the solid casting residue steel 7. If the solid casting residue steel 7 is still partially attached to the inner wall of the tank, the separation tank 8 can be repeatedly lifted and lowered several times by hoisting equipment to use the impact force to promote the complete separation of the solidified slag steel from the tank body, improve the separation effect, and ensure that the slag steel can be completely separated from the tank body. Step 6: Using hoisting equipment, the separation tank 8, which has already been preliminarily separated from the solid casting residue steel 7, is continued to be hoisted to the slag yard 6. The solid casting residue steel 7 in the separation tank 8 is poured out. The poured-out solid casting residue steel 7 can be further processed and recycled to achieve resource recycling. Then, the empty separation tank 8 is placed on top of the car body 51, so that the hoisting trunnion 81 is locked in the slot 54 to complete the reset of the separation tank 8. The inner wall of the separation tank 8 to be filled is re-sprayed with anti-stick coating. Then, the above steps 1 to 5 are repeated to realize the cyclic operation of the separation device, continuously separating the ladle casting residue and ensuring the continuity of continuous casting production.

[0023] In summary, compared with the prior art, the continuous casting machine slag steel separation device and method of the present invention have the following advantages and positive effects: (1) The present invention temporarily stores liquid casting residue steel 7 in storage tank 3 and then orderly fills it into separation tank 8, which avoids the overflow foaming and equipment damage caused by directly pouring casting residue into empty steel ladle in the empty steel ladle recycling method. At the same time, the inner wall of separation tank 8 is sprayed with anti-stick coating, which avoids the problem of casting residue crusting and sticking to the ladle in the molten iron ladle recycling method, extends the service life of the equipment, reduces the equipment maintenance cost, and achieves efficient and natural separation of solid casting residue steel 7 and separation tank 8 through the cooperation of separation components and anti-stick coating, without the need for additional cutting and processing procedures, reducing scrap steel burning loss and smoke pollution, greatly improving the metal recovery rate and reducing resource waste; (2) In this invention, the entire device is automatically controlled by the control module. The drive vehicle 4, the sealing switch 31, and the hoisting equipment are all controlled by the control module. No manual operation is required, which reduces the labor intensity of the operators. At the same time, the separation tank 8 can be recycled, reducing waste generation and environmental burden. Multiple tank cars 5 and separation tanks 8 are set up. The storage tank 3 continuously receives the ladle casting residue. Multiple separation tanks 8 are filled, transferred, separated, and reset in sequence, realizing the continuous treatment of casting residue slag steel 7, greatly improving the processing efficiency and adapting to the continuous needs of continuous casting production.

Then, the liquid slag steel in the ladle is poured into the storage tank. The inner wall of the separation tank to be filled is sprayed with the anti-stick coating in advance. Step 2: The drive vehicle moves the tanker along the circular track and passes under the storage tank. When the first separation tank behind the drive vehicle moves to the bottom of the storage tank, the control module controls the drive vehicle to stop moving and simultaneously controls the sealing switch to the open state. The liquid casting residue steel flows into the first separation tank through the drain. At this time, under the action of gravity, the bottom end of the top plate in the separation assembly is attached to the bottom end of the inner wall of the separation tank.
