Description

Technical Field

[0001] This utility model relates to the field of electrode cylinder production technology, and more specifically to a trolley device for manufacturing self-baking electrode cylinders for large titanium slag electric furnaces. Background Technology

[0002] Currently, the electrode cylinder manufacturing process is indispensable in large-scale self-baking electrode titanium slag electric furnaces in the metallurgical industry. Especially when production tasks are heavy, the use of advanced and efficient manufacturing tools can greatly reduce the input of personnel, labor intensity, and improve work efficiency. The application of mechanized equipment has become widespread and necessary. The self-baking electrode cylinder manufacturing trolley is a special operating trolley manufactured specifically for self-baking electrode cylinders. After years of field use, it has been found that the original self-baking electrode cylinder manufacturing trolley, due to its large overall weight, could only be pushed entirely by manpower. Purely manual operation increased the waste of manpower, was very inconvenient to use, and the operation process was extremely difficult, time-consuming, labor-intensive, and inefficient. It also increased the safety risks and operational difficulty for operators.

[0003] CN 220288541 U discloses a measuring device for electrode paste in a calcium carbide furnace, comprising a track, a moving trolley, a ranging component, and a drive assembly. The track is positioned above the electrode cylinder and higher than the electrode paste inside. The moving trolley is slidably connected to the track. The ranging component is mounted on the moving trolley and can measure distances downwards. The drive assembly is connected to the moving trolley and drives it to move along the track. The drive assembly includes a first roller, a second roller, and an open connecting rope. The first roller is located at a first end of the track, and the second roller is located at a second end of the track. The open connecting rope is wound around the first and second rollers, and both ends of the rope are connected to the two ends of the moving trolley along its direction of movement. A crank is provided on the first roller to provide power to the moving trolley. This prior art uses a moving trolley to carry the ranging component to move above the electrode cylinder to measure the electrode paste. Workers only need to operate the drive assembly and do not need to reach above the electrode paste, reducing safety hazards during operation. However, this prior art uses manual control of the drive assembly to control the movement of the trolley, which poses a safety hazard.

[0004] CN 111874651 Disclosed in section A is a double-rope, double-connection mechanism for an automatic telescopic conveyor belt machine. Two upper-outgoing steel wire ropes are connected to an electric winch, and two lower-outgoing steel wire ropes are also connected to the electric winch. The two upper-outgoing steel wire ropes are connected to a support pulley block, and an upper-outgoing steel wire rope balancing mechanism is connected to the support pulley block. The two lower-outgoing steel wire ropes are connected to a redirecting pulley block, which is connected to the lower-outgoing steel wire rope balancing mechanism via a roller support block. The two middle steel wire ropes on the electric winch drum are upper-outgoing ropes, connecting to the tail end of the conveyor belt machine's moving truss; while the two steel wire ropes on either side of the drum are lower-outgoing ropes, connecting to the side ends of the conveyor belt machine's moving truss. When the electric winch rotates forward, the two middle steel wire ropes on the drum release their ropes, and the two side steel wire ropes retract their ropes, controlling the conveyor belt machine's moving truss to extend outward. When the electric winch rotates in reverse, the two middle steel wire ropes on the drum retract their ropes, and the two side steel wire ropes release their ropes, controlling the conveyor belt machine's moving truss to retract. The existing technology primarily relies on roller blocks for horizontal movement of the wire rope, and pulley blocks for directional movement, thus enabling the automatic extension and retraction of the conveyor belt's moving truss. However, while this technology allows for the extension or retraction of the conveyor belt's moving truss, it does not achieve back-and-forth movement.

[0005] CN 221064916 U discloses a welding carriage, including a base, chucks, a cylinder, a synchronous shaft, and a brake disc. The base includes two support plates, with a base plate fixed between the bottom ends of the two support plates. A pair of axles are fixed to the bottom of the base plate, and the ends of the axles have rotatable wheels. Two chucks are coaxially positioned between the two support plates and are rotatably connected to the support plates via rotating shafts. One rotating shaft passes through a support plate and is fixed to a hand crank. The two chucks can rotate. The cylinder body is fixed to the support plate, and clamps are distributed circumferentially on the opposing surfaces of the two chucks. The synchronous shaft is positioned below the two chucks, with one end rotatably connected to a support plate and the other end passing through the other support plate and fixed to the brake disc. This prior art, by setting up a welding carriage, can support and pre-assemble the electrode cylinder, and correspondingly splice the arc-shaped plate and stiffening plate before direct welding and fixing, avoiding welding errors and rework, thus improving efficiency. However, this prior art does not disclose the controllable movement of the welding carriage.

[0006] Based on this, there is room for improvement in the control of the movement of the self-baking electrode cylinder fabrication trolley. Utility Model Content

[0007] In view of this, the purpose of this utility model is to provide a trolley device for the fabrication of self-baking electrode cylinders in large titanium slag electric furnaces, so as to solve the technical problems of difficult manual operation and low efficiency of existing self-baking electrode cylinder fabrication trolleys.

[0008] To solve the above-mentioned technical problems, this utility model provides a trolley device for manufacturing self-baking electrode cylinders for large titanium slag electric furnaces, including a winch, a flexible transmission medium, a control element, a pulley, and a transport vehicle. The flexible transmission medium is wound and connected to the winch and passes around the pulley. The transport vehicle is located between the winch and the pulley and is aligned with the winch and the pulley.

[0013] In some embodiments, the control element includes a control switch electrically connected to the winch's controller.

[0014] In some embodiments, the control element includes a foot control switch electrically connected to the controller of the electric winch.

[0015] In some embodiments, the foot control switch includes a first switch and a second switch. The first switch controls the controller of the electric winch to control the motor of the electric winch so that the drum of the electric winch rotates in a clockwise direction. The second switch controls the controller of the electric winch to control the motor of the electric winch so that the drum of the electric winch rotates in a counterclockwise direction. When neither the first switch nor the second switch is working, the electric winch stops.

[0016] In some embodiments, the trolley device for fabricating self-baking electrode cylinders for large titanium slag electric furnaces includes a support roller disposed between and adjacent to a winch and a pulley, with a flexible transmission medium supported on the support roller between the bottom of the winch drum and the bottom of the pulley.

[0017] In some embodiments, the trolley device for fabricating self-baking electrode cylinders for large titanium slag electric furnaces includes a track on which the four wheels of the transport vehicle are located.

[0018] Through the above technical solution, the trolley device for manufacturing self-baking electrode cylinders for large titanium slag electric furnaces provided by this utility model changes the direction of the flexible transmission medium through pulleys, so that the flexible transmission medium can wrap around the winch and go around the pulleys, and the two ends of the flexible transmission medium are respectively connected to the front end and the rear end of the transport vehicle. The winch is controlled by control elements to realize the movement of the flexible transmission medium, and then the flexible transmission medium pulls the transport vehicle to move, thus solving the technical problems of difficult manual operation and low efficiency of existing self-baking electrode cylinder manufacturing trolleys.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be further described in detail below with reference to specific examples and accompanying drawings.

[0026] It should be noted that all uses of "first" and "second" in the embodiments of this utility model are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model. Subsequent embodiments will not explain this in detail.

[0027] Furthermore, "vertical" is not strictly vertical, but rather within the allowable margin of error. Similarly, "parallel" is not strictly parallel, but also within the allowable margin of error. Words such as "include" or "contain" mean that the element preceding the word covers the element listed after it, without excluding the possibility of including other elements as well.

[0028] All terms used in this invention have the same meaning as understood by one of ordinary skill in the art to which this invention pertains, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and not as idealized or highly formalized, unless expressly defined herein.

[0029] The self-baking electrode cylinder manufacturing trolley is a piece of equipment used to manufacture self-baking electrode cylinders. Its main functions include: material transportation (carrying materials such as metal sheets, electrode paste, and steel strips from warehouses or storage areas to various processing stations, and transporting scraps and waste generated during manufacturing to the waste disposal area); semi-finished product transfer (carrying semi-finished electrode cylinders during manufacturing, transporting them from cutting and rolling stations to subsequent stations such as welding, reinforcement, and electrode paste filling, ensuring smooth transitions between processes); finished product handling (after manufacturing, the trolley can transport finished self-baking electrode cylinders to warehouse storage or load them for shipment, facilitating transportation and storage); auxiliary positioning (some trolleys are equipped with positioning devices or clamps to position and fix the electrode cylinders during manufacturing, facilitating welding, measurement, and other operations, ensuring manufacturing accuracy and quality); and improved efficiency (the trolley can carry multiple materials or semi-finished products at once, reducing manual handling and allowing for rapid movement between workstations, thereby improving overall manufacturing efficiency and reducing labor intensity).

[0030] like Figure 1 and Figure 2 As shown, when the existing self-baking electrode cylinder manufacturing trolley 8 moves during the self-baking electrode cylinder manufacturing process, personnel 9 need to push or pull the self-baking electrode cylinder manufacturing trolley 8 to move it along a track (not shown). For safety and ease of operation for personnel 9, a platform 10 is provided on one side of the track, and personnel 9 move on the platform 10. The length direction of the platform 10 is parallel to the length direction of the track.

[0031] In some embodiments, platform 10 is made of wood. Figure 1 The operator 9 pushes the existing self-baking electrode cylinder manufacturing trolley 8 along the first direction F1. Figure 2The operator 9 pushes the existing self-baking electrode cylinder manufacturing trolley 8 along the second direction F2. By having the operator 9 push the existing self-baking electrode cylinder manufacturing trolley 8 along the first direction F1 or the second direction F2, the existing self-baking electrode cylinder manufacturing trolley 8 moves back and forth along the track, thus realizing the back-and-forth movement of the existing self-baking electrode cylinder manufacturing trolley 8 carrying the self-baking electrode cylinder.

[0032] Because the existing self-baking electrode cylinder manufacturing trolley 8 is quite heavy, it is wasteful for personnel 9 to push or pull the self-baking electrode cylinder manufacturing trolley 8 to move, and the operation process is extremely difficult, time-consuming, labor-intensive, and inefficient. It also increases the safety risks and operational difficulty for personnel 9.

[0033] This utility model provides a trolley device for manufacturing self-baking electrode cylinders for large titanium slag electric furnaces, such as... Figure 3 As shown, the device includes a winch 1, a flexible transmission medium 2, a control element 3, a pulley 4, and a transport vehicle 5. The flexible transmission medium 2 is wound around the winch 1 and passes around the pulley 4. The transport vehicle 5 is located between the winch 1 and the pulley 4 and is aligned with them. The two ends of the flexible transmission medium 2 are connected to the front and rear ends of the transport vehicle 5, respectively, allowing the transport vehicle 5 to move between the winch 1 and the pulley 4. The control element 3 is electrically connected to the winch 1 and controls its rotation. The front and rear ends of the transport vehicle 5 are defined based on its direction of travel. The direction in which the transport vehicle 5 moves away from the winch 1 is the forward direction of travel, while the direction in which it moves towards the winch 1 is the reverse direction of travel. The front end of the transport vehicle 5 is the foremost end of the transport vehicle 5 when it moves in the forward direction, and the rear end of the transport vehicle 5 is the rearmost end of the transport vehicle 5 when it moves in the forward direction.

[0034] Compared with the prior art, the trolley device for the fabrication of self-baking electrode cylinders in large titanium slag electric furnaces of this utility model changes the direction of the flexible transmission medium 2 through the pulley 4, so that the flexible transmission medium 2 can wrap around the winch 1 and pass around the pulley 4, and the two ends of the flexible transmission medium 2 are respectively connected to the front end and the rear end of the transport tool 5. The winch 1 is controlled by the control element 3 to realize the movement of the flexible transmission medium 2, and then the flexible transmission medium 2 pulls the transport tool 5 to move, thus solving the technical problems of difficult manual operation and low efficiency of existing self-baking electrode cylinder fabrication trolleys.

[0035] In some embodiments, the flexible transmission medium 2 includes a first end and a second end, the first end being connected to the front end of the vehicle 5 and the second end being connected to the rear end of the vehicle 5.

[0036] In some embodiments, the second end of the flexible transmission medium 2 is configured such that: the second end is introduced from above the pulley 4 and passes around the pulley 4 before being led out from below the pulley 4, thereby changing the direction of the flexible transmission medium 2 by approximately 180°; the second end, after being led out from below the pulley 4, is introduced from below the drum of the winch 1 and wound around the drum several times before being led out from above the drum, ensuring that the winch 1 moves the flexible transmission medium 2 through the winding of the drum, and the direction of the flexible transmission medium 2 changes by approximately 180° again.

[0037] In some embodiments, the first end of the flexible transmission medium 2 is configured such that: the first end is introduced from above the drum of the winch 1 and wound around the drum several times before being led out from below the drum, ensuring that the winch 1 moves the flexible transmission medium 2 through the winding of the drum, and the direction of the flexible transmission medium 2 changes by approximately 180°; the first end, after being led out from below the drum of the winch 1, is introduced from below the pulley 4 and passes around the pulley 4 before being led out from above the pulley 4, thus achieving another approximately 180° change in the direction of the flexible transmission medium 2.

[0038] After the flexible transmission medium 2 is wound and connected to the winch 1 and passes around the pulley 4, the direction of the flexible transmission medium 2 changes by approximately 360°, at which point the first end and the second end of the flexible transmission medium 2 are opposite each other.

[0039] In some embodiments, the flexible transmission medium 2 is wound around the drum of the winch 1 at least 4 times. For example, the flexible transmission medium 2 is wound around the drum of the winch 1 7-8 times to ensure sufficient friction between the flexible transmission medium 2 and the drum, prevent slippage or derailment, and provide cushioning to reduce stress concentration.

[0040] In some embodiments, the flexible transmission medium 2 includes a steel wire rope, which is wound around the winch 1 and passes over the pulley 4. For example, the steel wire rope is a plastic-coated steel wire rope, which has the advantages of strong corrosion resistance, good wear resistance, good flexibility, and good insulation performance, and is suitable for the environment in which self-baking electrode cylinders are manufactured. For example, the steel wire rope can be a stainless steel wire rope.

[0041] In some embodiments, the winch 1 includes an electric winch, and the flexible transmission medium 2 is wound and connected to the drum of the electric winch. For example, a wire rope is wound and connected to the drum of the electric winch. The second end of the wire rope is introduced from below the drum of the electric winch and wound around the drum several times before being led out from above the drum, or the first end of the wire rope is introduced from above the drum of the electric winch and wound around the drum several times before being led out from below the drum.

[0042] In some embodiments, the electric winch can be a conventional electric winch that is available on the market. For example, the electric winch can be a direct-drive electric winch that includes a motor, a drum, a brake, a frame, and a controller. The motor directly drives the drum to rotate, thereby enabling the flexible transmission medium 2 wound on the drum to move relative to the axis of the drum, for example, in a direction perpendicular to the axis of the drum.

[0043] In some embodiments, the electric winch can be a self-made electric winch, including a motor, drum, brake, frame, and controller. The motor, drum, brake, and controller are mounted on the frame. The motor is connected to the drum via a driving pulley, a belt, and a driven pulley. The driving pulley is coaxially connected to the motor, the driven pulley is coaxially connected to the drum, and the belt connects the driving and driven pulleys. The motor drives the driving pulley to rotate, and the belt transmits power to the driven pulley, thereby driving the drum shaft to rotate. The drum is used to wind the flexible transmission medium 2, and the rotation of the drum realizes the winding and unwinding of the flexible transmission medium 2. The brake can quickly brake the drum when the electric winch stops working or in an emergency. The controller is used to control the start, stop, forward and reverse rotation, and speed adjustment of the motor, precisely controlling the operation of the electric winch.

[0044] Reference Figure 3 When the drum of the electric winch rotates clockwise (forward), the first end of the flexible transmission medium 2 wound around the drum is subjected to force, and the first end pulls the front end of the transport vehicle 5, causing the transport vehicle 5 to move in the forward running direction. When the drum of the electric winch rotates counterclockwise (reverse), the second end of the flexible transmission medium 2 wound around the drum is subjected to force, and the second end pulls the rear end of the transport vehicle 5, causing the transport vehicle 5 to move in the reverse running direction.

[0045] In some embodiments, pulley 4 includes a guide pulley, with the flexible transmission medium 2 bypassing the groove of the guide pulley. For example, a wire rope bypasses the groove of the guide pulley. A second end of the wire rope is introduced from above the guide pulley, bypasses the groove, and then exits from below the guide pulley; or a first end of the wire rope is introduced from below the guide pulley, bypasses the groove, and then exits from above the guide pulley.

[0046] like Figure 3 As shown, after the wire rope is wound and connected to the electric winch and passes over the guide pulley, the first end of the wire rope is connected to the front end of the transport vehicle 5, and the second end of the wire rope is connected to the rear end of the transport vehicle 5. The transport vehicle 5 is located between the electric winch and the guide pulley and is aligned with both. This design ensures that the electric winch controls the movement of the wire rope, thereby controlling the movement of the transport vehicle 5 between the electric winch and the guide pulley.

[0047] In some embodiments, the control element 3 is electrically connected to the controller of the winch 1. The control element 3 controls the start, stop, and clockwise or counterclockwise rotation of the winch 1's drum by controlling the controller of the winch 1. For example, the control element 3 is electrically connected to the controller of an electric winch. The position of the control element 3 is not limited; the control element 3 can be positioned at a location that facilitates observation of the transport vehicle 5.

[0048] In some embodiments, the control element 3 includes a control switch, which is electrically connected to the controller of the winch 1.

[0049] In some embodiments, the control element 3 includes a foot control switch. The foot control switch is electrically connected to the controller of the winch 1. For example, the foot control switch is electrically connected to the controller of an electric winch.

[0050] In some embodiments, the foot control switch includes a first switch and a second switch. The first switch controls the controller of the electric winch to control the motor of the electric winch so that the drum of the electric winch rotates clockwise. The second switch controls the controller of the electric winch to control the motor of the electric winch so that the drum of the electric winch rotates counterclockwise. When the first switch is active, the drum of the electric winch rotates clockwise, and the wire rope wound on the drum pulls the transport vehicle 5 to move in the forward direction of the transport vehicle 5. When the second switch is active, the drum of the electric winch rotates counterclockwise, and the wire rope wound on the drum pulls the transport vehicle 5 to move in the reverse direction of the transport vehicle 5. When neither the first nor the second switch is active, the electric winch stops. This design ensures that the foot control switch can control the electric winch, thereby controlling the movement of the transport vehicle 5, and thus controlling the movement of the self-baking electrode cylinder carried by the transport vehicle 5.

[0051] In some embodiments, the vehicle 5 includes two pairs of wheels 7, which are respectively located near the front and rear ends of the vehicle 5, and the four wheels 7 are arranged in a manner located at the four vertices of a rectangle.

[0052] In some embodiments, the carrier 5 includes a carrier top whose shape matches the shape of the self-baking electrode cylinder. This design ensures that the self-baking electrode cylinder can be stably positioned on the carrier 5.

[0053] In some embodiments, the trolley device for fabricating self-baking electrode cylinders for large titanium slag electric furnaces according to this invention includes a track (not shown), on which the four wheels 7 of the transport vehicle 5 are located. The length direction of the track is approximately parallel to the length direction of the flexible transmission medium 2 located between the winch 1 and the pulley 4. This design ensures that when the flexible transmission medium 2 pulls the transport vehicle 5, the transport vehicle 5 can move linearly along the track.

[0054] In some embodiments, the track comprises two parallel steel rails. The two wheels 7 on the same side of the vehicle 5 correspond to one of the steel rails of the track.

[0055] In some embodiments, the trolley device for fabricating self-baking electrode cylinders for large titanium slag electric furnaces according to this invention includes a support roller 6. The support roller 6 is positioned between and adjacent to the winch 1 and the pulley 4. The flexible transmission medium 2, located between the bottom of the winch 1 drum and the bottom of the pulley 4, is supported on the support roller 6. The support roller 6 is aligned with the winch 1 and the pulley 4. The support roller 6 supports and guides the flexible transmission medium 2, reducing friction and resistance during its movement, ensuring smoothness during transport or rotation, improving work efficiency and reliability, and also bearing and dispersing pressure, protecting the flexible transmission medium 2 in contact with it, and extending its service life.

[0056] In some embodiments, the groove of the support roller 6 is in direct contact with the flexible transmission medium 2, bears the weight of the flexible transmission medium 2, and distributes the force evenly to the spokes and hub of the support roller 6.

[0057] In some embodiments, the groove of the roller 6 is aligned with the groove of the drum of the winch 1 and the pulley 4, which largely ensures that the flexible transmission medium 2 supported by the roller 6 and located between the winch 1 and the pulley 4 is in a straight line during operation.

[0058] In some embodiments, the center of the groove of the support roller 6, the center of the drum of the winch 1, and the center of the groove of the pulley 4 are on a straight line and the line is parallel to the track, such that the length direction of the flexible transmission medium 2 supported by the support roller 6 and located between the winch 1 and the pulley 4 is approximately parallel to the length direction of the track. This design ensures that the direction of the force exerted by the flexible transmission medium 2 on the transport vehicle 5 is approximately parallel to the length direction of the track, so that the direction of movement of the transport vehicle 5 is parallel to the length direction of the track, thereby ensuring that the transport vehicle 5 moves smoothly along the track.

[0059] In some embodiments, the transport vehicle 5 is a trolley 8 for manufacturing existing self-baking electrode cylinders.

[0060] In some embodiments, the winch 1 and pulley 4 can be manufactured by welding together existing pulleys and miniature winches left on-site as base materials when modifying the existing self-baking electrode cylinder manufacturing trolley 8. The operation of the miniature winch is designed with a foot pedal control switch to control the miniature winch, which allows the personnel 9 to operate with both hands while controlling the foot pedal control switch with one foot to control the movement of the transport vehicle 5. The manufactured winch 1 and pulley 4, together with the wire rope and the existing self-baking electrode cylinder manufacturing trolley 8, form the trolley device of this utility model for manufacturing self-baking electrode cylinders for large titanium slag electric furnaces, which saves costs and fulfills the task of repairing and reusing old materials.

[0061] In some embodiments, the trolley device for fabricating self-baking electrode cylinders for large titanium slag electric furnaces according to this invention is equipped with a platform 10. Since the electrode cylinder fabrication is an energized operation, a platform 10 is provided on one side of the entire trolley device to facilitate production continuity. The platform 10 is an effective insulating platform formed by laying and fixing wooden blocks.

[0062] The process of using the trolley device for manufacturing self-baking electrode cylinders in a large titanium slag electric furnace according to this utility model is as follows: First, the wire rope is wound and connected to the electric winch, passes around the guide pulley and is supported on the support roller 6. The two ends of the wire rope are respectively connected to the front end and the rear end of the transport vehicle 5. The foot pedal control switch is electrically connected to the controller of the electric winch. Second, the foot pedal control switch is controlled by one foot to control the controller of the electric winch to control the start, stop and clockwise or counterclockwise rotation of the electric winch drum, thereby controlling the running direction of the transport vehicle 5 and controlling the movement and stopping of the transport vehicle 5 to manufacture the self-baking electrode cylinder.

[0063] For example, during the electrode cylinder welding process, when the seam welding wheel of the seam welding machine is welding the electrode cylinder, the foot control switch is used to control the controller of the electric winch to control the electric winch drum to rotate clockwise, so that the wire rope pulls the transport vehicle 5 to move along the positive running direction of the transport vehicle 5 until the weld is completed, and then the electric winch stops.

[0064] The trolley device for manufacturing self-baking electrode cylinders for large titanium slag electric furnaces has shown good results after its use, greatly reducing the labor intensity of personnel and improving work efficiency; it saves a lot of manpower and downtime (reducing the number of three people working to one person), and lowers cost consumption.

[0065] This invention, through the design and installation of a trolley device for the fabrication of self-baking electrode cylinders in large titanium slag electric furnaces, significantly reduces the operational difficulty and manpower required. It also mitigates the impact of low electrode cylinder fabrication efficiency on production, ensuring safety and reliability. This invention solves the technical problems of difficult electrode cylinder fabrication, mismatched tools, and low efficiency leading to wasted manpower. It is applicable to the electrode cylinder fabrication process in large self-baking electrode-type titanium slag electric furnaces in the metallurgical industry, enabling efficient, convenient, and labor-saving specialized electrode cylinder fabrication. The trolley device has a long service life, low failure rate, is economical and practical, and is convenient and reliable to operate and maintain, saving labor and increasing efficiency. It prevents problems such as manual pushing operations, operational difficulties, production interruptions, and safety hazards for operators. Applied to the fabrication process of electrode cylinders for large self-baking electrode-type titanium slag electric furnaces in the metallurgical industry, it offers convenient and simple operation and maintenance, saving significant manpower and downtime, reducing costs, improving work efficiency, and creating substantial economic and social benefits.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
