[0031] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0032] Please refer to Figure 1 In an embodiment of the present application, an electroslag smelting device is provided, which includes a main frame 10, a mobile mechanism 20, a tensioning mechanism 30 and a mobile drive mechanism 40, and a reaction container 63 is also provided. A solid reactant 70 is placed in the reaction container 63 for reaction. The solid reactant 70 is illustrated by taking an electrode as an example. The main frame 10 serves as the basis of the entire device and provides support for the mobile mechanism 20 and the tensioning mechanism 30. The mobile mechanism 20 is slidably connected to the main frame 10. For example, the mobile mechanism 20 and the main frame 10 are connected through a fixed pulley and a steel rope, and the fixed pulley is installed on the main frame 10. One end of the steel rope is connected to the mobile drive mechanism 40, and the other end is connected to the fixed pulley and then connected to the mobile mechanism 20. In this way, the mobile drive mechanism 40 can drive the mobile mechanism 20 to adjust its height up and down by pulling the steel rope, thereby realizing the movement of the mobile mechanism 20. In an optional embodiment, a vertical slide groove is provided on the outer side of the main frame 10, and the side of the mobile mechanism 20 matches the slide groove, so that the mobile mechanism 20 is also slidably connected to the main frame 10.

[0033] The tensioning mechanism 30 is used to clamp and fix the solid reactant 70. The tensioning mechanism 30 is connected to the moving mechanism 20. The tensioning mechanism 30 and the moving mechanism 20 can be fixed by screws, bolts, welding, etc. The tensioning mechanism 30 adjusts the height along with the moving mechanism 20, and the electrode also adjusts the height accordingly. The moving mechanism 20 adjusts the electrode position in the axial direction of the electrode, and the tensioning mechanism 30 fixes the electrode in the radial direction of the electrode. The tensioning mechanism 30 can use a clamping arm, which can rotate. After the clamping arm rotates, it clamps and fixes the electrode. The clamping arm can be fixed to the moving mechanism 20 by parts such as bolts, and a driver 42 such as an electric cylinder, a hydraulic cylinder or a cylinder can also be provided to drive the clamping arm through the output end of the driver 42 Rotation; in an optional embodiment, the tensioning mechanism 30 can also adopt other structures that can clamp and fix the electrode, such as hydraulic clamps, etc.; the mobile drive mechanism 40 is transmission connected to the mobile mechanism 20, such as the output end of the mobile drive mechanism 40 is connected to the steel rope, the output end of the mobile drive mechanism 40 can also be directly connected to the mobile mechanism 20, so that the mobile drive mechanism 40 can directly drive the mobile mechanism 20, the mobile drive mechanism 40 adopts a motor, an electric cylinder, a hydraulic cylinder or other devices that can be driven, and the mobile drive mechanism 40 is used to drive the mobile mechanism 20 to move relative to the main frame 10 to adjust the position of the solid reactant 70 clamped by the tensioning mechanism 30 into the reaction vessel 63.

[0034] In the electroslag remelting process of the prior art, the electrode is moved into the reaction vessel 63 by manual operation, assisted by a simple clamping device, and there is no device for facilitating the operation of the electrode. In the prior art electroslag process, manual operation can hardly ensure that the electrode moves to the precise position each time. This is due to the limitations of human eye judgment and hand operation, which may cause electrode position deviation, which will affect the stability of the electroslag process and product quality. In addition, it is difficult for workers to achieve stable electrode movement speed by manual operation. Different workers have different operating habits. Even the operating speed of the same worker may fluctuate at different times. In addition, due to the long electroslag time, manual control of the electrode movement for a long time is a high-intensity physical labor for workers. In addition, it is necessary to observe the electroslag situation closely, and personnel safety cannot be guaranteed.

[0035] The present application adopts a mechanical structure to operate the electrode, avoiding manual close contact with the electrode. The mobile mechanism 20 is driven by the mobile driving mechanism 40, so that the mobile mechanism 20 can move relative to the main frame 10, so that the solid reactant 70 can be adjusted and controlled to enter the reaction container 63. The solid reactant 70 can be clamped and fixed tightly by the tensioning mechanism 30, so that the solid reactant 70 can always be clamped and the position of the solid reactant 70 can be adjusted as the reaction proceeds. The solid reactant 70 is an electrode in the electroslag process, so the movement of the electrode can be effectively adjusted and controlled in real time, and the electrode can be stably adjusted to ensure the reaction, avoiding the inconvenience of manual operation and the resulting adjustment deviation; at the same time, the use of a combined electromechanical device structure can significantly improve production efficiency.

[0036] Please refer to Figure 2 and Figure 3 In some embodiments, the moving mechanism 20 includes: a clamping head 21, a moving body 22 and a back-rest wheel, the back-rest wheel is arranged on the moving body 22, and there are a plurality of back-rest wheels, and the wheel surfaces of the plurality of back-rest wheels are kept in contact with the outer side of the main frame 10, the moving body 22 is fixed to the clamping head 21, and the moving body 22 can be fixed at both upper and lower ends of the clamping head 21, and the up and down movement of the clamping head 21 is guided and adjusted by the back-rest wheels installed on the moving body 22, the clamping head 21 is provided with a through opening, and the main frame 10 is arranged at the through opening, so that the clamping head 21 is matched with the main frame 10, and the moving body 22 is arranged around the main frame 10, and there is a group of multiple back-rest wheels on each surface around the main frame 10, so that the clamping head 21 is slidably connected to the main frame 10 through the back-rest wheels, and the clamping head 21 is transmission-connected with the moving driving mechanism 40, and the moving driving mechanism 40 is such as a hydraulic cylinder, an electric cylinder or other driver 42 that can generate a driving force, and the moving driving mechanism 40 drives the clamping head 21 to move up and down.

[0037] In some embodiments, the mobile mechanism 20 further includes a mobile winding wheel group 24, a rope 25 and a fixing member 26. The three components provide another transmission mode between the clamp 21 and the mobile driving mechanism 40. The mobile winding wheel group is a fixed pulley group. The mobile winding wheel group 24 is installed at the upper position of the main frame 10. The fixing member 26 is connected to the clamp 21. The fixing member 26 can be an anchor bolt, which is threadedly connected to the top surface of the clamp 21. The rope 25 is a steel wire rope, a high-strength nylon rope, etc. One end of the rope 25 is connected to the fixing member 26, such as bolting or tying. In this way, the chuck 21 can be driven to move up and down in the vertical direction through the rope 25. The rope 25 is slidably matched with the movable winding wheel group 24. The movable winding wheel group 24 plays a guiding role. The movable winding wheel group 24 is set on both sides of the main frame 10. After the rope 25 passes around the movable winding wheel group 24 on both sides, the other end of the rope 25 is connected to the movable driving mechanism 40 for transmission. If the movable driving mechanism 40 adopts a winding machine, the end of the rope 25 is connected to the winding roller, and the length of the rope 25 is adjusted by rotation, thereby changing the height of the chuck 21.

[0038] In some embodiments, the moving mechanism 20 also includes a conductive member 27 and a conductive connector 28. The conductive connector 28 is disposed on the side of the clamp 21 facing the fixed reactant. The conductive connector 28 is used to contact the electrode and energize the electrode. The conductive connector 28 may be a plate-like structure on the side of the clamp 21. The conductive connector 28 is spaced apart from the clamp 36 described below. When the clamp 36 clamps the electrode, the electrode is fixed at the conductive connector 28. The conductive member 27 is disposed on the clamp 21 and is electrically connected to the conductive connector 28. The conductive member 27 is disposed in order to connect external electricity to the conductive connector 28. The conductive member 27 is disposed on other sides of the clamp 21, so that the conductive member 27 can conduct electricity to the conductive connector 28 from one side of the clamp 21. In an optional embodiment, the moving mechanism 20 also includes an insulating member 29, which is in the form of a sheet or a block. The insulating member 29 is embedded in the clamp 21. The insulating member 29 is located close to the main frame 10. The insulating member 29 is in contact with the conductive connecting member 28. The insulating member 29 is arranged to ensure that the conductive member 27 only conducts current to the conductive connecting member 28 and does not allow other positions of the moving mechanism 20 to conduct electricity.

[0039] Please refer to Figure 2 and Figure 3In some embodiments, the tensioning mechanism 30 includes a clamping member 36, a clamping seat 35, a shaft seat 34 and a tensioning drive unit. The tensioning mechanism 30 provides a basis for clamping and fixing the electrode. When clamping and fixing, one side of the electrode is against the side of the clamp head 21, and the other side of the electrode is fixed by the clamping member 36. One end of the clamping member 36 is used to clamp the solid reactant 70, and the other end is hinged to the shaft seat 34. The shaft seat 34 and the end of the clamping member 36 are hinged by a pin connection. A part of the clamping member 36 can be set as an arc segment, and the shape of the arc segment matches the outer side of the electrode, so that the arc segment can effectively clamp the electrode. The clamping seat 35 is installed on the clamp head 21, and the clamping seat 35 serves as a rotation connection base for the clamping member 36. The clamping member 36 is hinged to the clamping fixed seat 35, and the hinge can be formed by a pin connection method, or the clamping fixed seat 35 can directly adopt a hinge structure. The clamping position of the clamping member 36 and the shaft seat 34 are located on both sides of the clamping fixed seat 35. Operating the shaft seat 34 can drive the clamping member 36 to rotate, thereby achieving clamping of the electrode. The shaft seat 34 is connected to the tensioning drive unit. For example, the tensioning drive unit adopts a hydraulic cylinder, a pneumatic cylinder or other driver 42. The output end of the tensioning drive unit is directly fixed to the shaft seat 34. The tensioning drive unit is used to drive the shaft seat 34 to move axially along the output end of the tensioning drive unit, so that the clamping member 36 can clamp the solid reactant 70 after rotating, or when driven in the opposite direction, the clamping member 36 opens the distance with the clamping head 21 to replace the electrode.

[0040] In some embodiments, the tensioning drive unit includes a tensioning fixed seat 31, a tensioning driver 32 and an extension shaft 33. The tensioning fixed seat 31 serves as an installation base for the driver 42. The tensioning fixed seat 31 is installed on one side of the clamping head 21. The tensioning driver 32 is embedded in the installation groove provided in the tensioning fixed seat 31. One end of the extension shaft 33 is connected to the output end of the tensioning driver 32, and a coupling can be used for connection. After the extension shaft 33 passes through the shaft hole on the tensioning fixed seat 31, the other end of the extension shaft 33 is connected to the shaft seat. 34 is connected, the tensioning driver 32 adopts a cylinder, and other drivers 42 capable of generating linear motion may also be adopted, the cylinder is connected to the air source system, and the output end of the tensioning driver 32 drives the shaft seat 34 to move along the axial direction of the extension shaft 33, thereby driving the shaft seat 34 to make back and forth linear motion, when the extension shaft 33 reaches the maximum stroke, the clamping member 36 rotates under the drive of the shaft seat 34, and clamps and fixes the electrode on the side of the clamping head 21, when the extension shaft 33 reduces the stroke, the clamping member 36 rotates and releases the electrode. In an optional embodiment, in order to ensure that the moving mechanism 20 has sufficient bearing capacity when clamping the electrode, a reinforcement member 38 may be provided on the side of the clamping head 21 facing the electrode, such as at both sides of the electrode mounting position, ribs are installed perpendicular to the outer side of the clamping head 21, and the reinforcement member 38 may be fixed to the clamping head 21 by welding, bolting or other methods.

[0041] In some embodiments, the tensioning mechanism 30 also includes a spring pretensioner 37, which includes a spring support 371, a tensioning spring 372 and a spring stopper 373. The spring support 371 is fixed to the outer side of the tensioning fixing seat 31, and the spring support 371 provides support for the tensioning spring 372. The spring stopper 373 is fixedly connected to the extension shaft 33, such as the spring stopper 373 is welded and fixed to the outer wall of the extension shaft 33. The two ends of the tensioning spring 372 are respectively connected to the spring stopper 373 and the spring support 371. In this way, the tensioning spring 372 can generate a force between the spring stopper 373 and the spring support 371, thereby providing a pretensioning force to the extension shaft 33. During the electroslag process, there may be a power outage or a touch, which may cause the cylinder to be cut off or damaged, and the consumable electrode cannot be fixed. At this time, the tension spring 372 exerts a force on the spring stopper 373 under compression, thereby driving the extension shaft 33 and the shaft seat 34 to move, so that the clamping member 36 maintains the clamping state of the consumable electrode. Due to the setting of the above-mentioned spring preload 37, the clamping member 36 rotates and clamps the electrode and no longer rotates, and is subject to the preload force of the spring preload 37, which can prevent the clamping member 36 from loosening after clamping the electrode, and maintain a good clamping and fixing effect.

[0042] Please refer to Figure 2 In some embodiments, the main frame 10 includes a column 11, at least two beams 12, a touch switch 14 and a buffer 15. The plurality of beams 12 are arranged at intervals on the column 11, such as two beams 12 welded to the column 11 one above the other. A moving winding wheel set 24 is installed on the top of the upper beam 12, and a touch switch 14 and a buffer 15 are fixed on the top of the lower beam 12. The touch switch 14 and the buffer 15 are located below the moving mechanism 20. In this way, when the clamping head 21 and the moving body 22 move toward When moving downward, it can ensure that the movement reaches the maximum stroke. The touch switch 14 adopts the existing pressure touch switch 14, and the buffer 15 adopts the existing spring buffer 15 to provide buffering for the abutment contact of the clamp 21. The touch switch 14 and the buffer 15 are both existing devices. The touch switch 14 is connected to the mobile drive mechanism 40 for communication. For example, when the clamp 21 moves to the crossbeam 12, it abuts against the touch switch 14. The touch switch 14 sends a signal to the controller connected to the mobile drive mechanism 40 to stop driving. In an optional embodiment, the main frame 10 also includes a bottom plate 13, which is in a plate shape and fixed to the ground of the working area. The bottom plate 13 serves as the bottom foundation of the entire device to ensure the working environment above it, wherein the bottom end of the column 11 is welded and fixed to the middle of the bottom plate 13, and the reaction vessel 63 is also fixed on the bottom plate 13.

[0043] Please refer to Figure 4In some embodiments, a dustproof mechanism 50 is further included. The dustproof mechanism 50 includes a protective plate 51, a protective door 52, a smoke hood 54 and a smoke pipe 55. The protective plate 51 and the protective door 52 are arranged on the periphery of the main frame 10. The protective plate 51 is fixed at a certain distance from the main frame 10. The protective door 52 is connected to the protective plate 51 through a hinge. The protective door 52 is set in an arc shape and can form a cylinder with the protective plate 51. The protective door 52 is opened by rotation to observe the electrode reaction. A lock can be designed between the protective door 52 and the protective plate 51 and a door lock 53 is installed to realize a closed electroslag process. The smoke hood 54 is connected to the top of the protective plate 51 and the protective door 52 by a cover setting method. For example, the smoke hood 54 is in a cover shape, and the bottom of the smoke hood 54 is welded and fixed to the top of the protective plate 51. The smoke pipe 55 is connected to the smoke hood 54. The smoke pipe 55 is connected to the inside of the above-mentioned cylinder structure. The smoke pipe 55 is used to connect an existing suction device or an air purification device, such as a smoke extractor, to process the smoke. Due to the above-mentioned setting of the dust-proof mechanism 50, a large amount of smoke generated during the electroslag process can be effectively absorbed and discharged, reducing the impact of smoke on surrounding personnel and maintaining a clean working environment; at the same time, long-term smoke and dirt may also corrode the device. After adopting the dust-proof mechanism 50, the service life of the equipment can be shortened and the equipment maintenance cost can be reduced.
