Description

Technical Field

[0001] This invention relates to the field of metal refining technology, specifically to a gas-protected electroslag remelting apparatus and process. Background Technology

[0002] Electroslag remelting is a smelting method that uses the resistance heat generated when an electric current passes through molten slag as a heat source. Its purpose is to improve the purity of the metal and enhance the crystallization of the ingot. Steel that has undergone electroslag remelting has high purity, low sulfur content, fewer non-metallic inclusions, a smooth, clean, uniform, and dense ingot surface, and uniform metallographic structure and chemical composition.

[0003] Chinese Patent (CN 116814966 A) discloses an electroslag remelting device, including a support, a crystallizer, and an electrode. The device is characterized by: a vertically extendable lifting unit slidably connected to the support along a horizontal direction; a movable frame connected to the extendable end of the lifting unit; a rotating frame rotatably connected to the movable frame, capable of swinging on a horizontal plane; a mounting frame slidably connected to the rotating frame along a horizontal direction; a second elastic unit connecting the mounting frame to the rotating frame; an electrode connected to the mounting frame via a clamp and capable of vertically entering and exiting the inside of the crystallizer; a positioning unit on the mounting frame that can descend and abut against the upper end of the crystallizer; the positioning unit forms a positioning cavity with a diameter gradually increasing from top to bottom, allowing the upper end of the crystallizer to be embedded; and the axis of the electrode is located at the center of the positioning cavity.

[0004] While the aforementioned patents can improve the smelting quality and efficiency of steel ingots and facilitate the removal of steel ingots, they can also lead to uneven heating of the electroslag ingots during the heating and melting process using consumable electrodes. This results in slow melting of the electroslag ingots. In addition, the electroslag ingots are relatively heavy, requiring manual feeding, which further slows down the melting process.

[0013] In the aforementioned gas-protected electroslag remelting device and process, a drive toothed plate is fixedly installed at the bottom of the slide plate, the drive toothed plate is meshed with a drive gear, the drive gear is unidirectionally driven and connected to the outer wall of the drive shaft, a discharge port is opened on the side wall of the feed box, the discharge port is flush with the feed of the consumable electrode, one end of the bottom of the slide plate is fixedly connected to a return spring, the other end of the return spring is fixedly connected to the inner bottom wall of the feed box, a limit box is installed on the inner bottom wall of the feed box, the limit box is opposite to the drive toothed plate, and the drive shaft is driven and connected to the drive shaft through a first transmission belt.

[0014] In the aforementioned gas-protected electroslag remelting device and process, a first limiting block is installed on the side wall of the bottom wall of the drive tooth plate, and a second limiting block is slidably connected to the inner side wall of the limiting box. The top of the second limiting block is set as an arc surface, and the bottom is a straight surface. The second limiting block matches the first limiting block. The outer wall of the second limiting block is fixedly connected to one end of a limiting spring, and the other end of the limiting spring is fixedly connected to the inner side wall of the limiting box. The end of the second limiting block away from the arc surface is fixedly connected to one end of a reset line, and one end of the reset line is located outside the base.

[0015] In the aforementioned gas-protected electroslag remelting device and process, the drive shaft is driven and connected to the push shaft via a second transmission belt. A second spiral spring is installed on the outer wall of one end of the push shaft, and the other end of the second spiral spring is fixedly connected to the inner side wall of the feeding box. A first connecting bevel tooth is installed on the outer wall of the push shaft, and the first connecting bevel tooth meshes with a second connecting bevel tooth. The second connecting bevel tooth is installed on the outer wall of one end of a bidirectional lead screw. A threaded block is threadedly connected to the outer wall of the bidirectional lead screw, and a push plate is installed on the outer wall of the threaded block.

[0016] In the aforementioned gas-protected electroslag remelting device and process, the outer wall of the push shaft is engaged with a second clamping box, the connecting line inside the second clamping box is connected to the stretching line, a drive cylinder is installed on the outer wall of the push shaft, the drive cylinder is connected to the second transmission belt, a limit strip is slidably connected to the outer wall of the push shaft, one end of the limit strip is connected to the inner ring of the first bearing ring, one end of the first bearing ring is connected to the second bearing ring through a tension spring, the outer wall of the first bearing ring is fixedly connected to one end of the release line, and the other end of the release line is connected to one end of the stretching line.

[0017] The beneficial effects of this invention are as follows: 1. By incorporating a rotating wheel, this invention enables the device to drive the electroslag ingot during melting, ensuring uniform heating and faster melting. This avoids slow melting caused by uneven heating. Furthermore, the feed box allows the device to store the gravity force of the incoming electroslag, which then powers the device without requiring additional power, automatically driving the rotating wheel and ensuring uniform heating.

[0018] 2. The top plate and sealing cover of the present invention can automatically seal the inside of the consumable electrode, preventing air from entering. At the same time, during feeding, they can drive the pressure plate to move upward synchronously. When the molten electroslag flows into the base, it can automatically open and spray out gas to further isolate the air and prevent secondary oxidation of the electroslag, which would result in high oxygen and impurity content in the steel.

[0019] 3. The rotating wheel of this invention is initially positioned outside the consumable electrode. When the material is pushed, it slides against the rotating wheel, facilitating contact with the electroslag block. This ensures that the rotating wheel is always in contact with the outer wall of the electroslag block, preventing the phenomenon where the diameter of the electroslag block decreases after melting, making it impossible for the rotating wheel to drive the block to rotate. This ensures that the rotating wheel can always drive the electroslag block to rotate, regardless of whether the diameter of the electroslag block decreases too quickly or too slowly. At the same time, the lower position of the rotating wheel avoids conflict with the downward pressure of the pressure plate. When the rotating wheel drives the electroslag block to rotate, it also cleans its bottom, preventing the electroslag solution from sticking together.

[0020] 4. By setting a top plate, the present invention enables the device to push the rotating wheel, and the top plate to press the pressing block, so that the pressing block can reset the rotation of the rotating shaft. At the same time, the second drive bevel tooth disengages from the first drive bevel tooth, automatically realizing the reset rotation of the device, so that the device can start automatically and achieve the effect of linkage with the pushed material without the need for additional operation.

[0021] 5. After the drive tooth plate descends to its limit position, it will descend into the interior of the limiting box. At this time, the first limiting block and the second limiting block abut against each other. The second limiting block acts as a locking and limiting block for the drive tooth plate, preventing the drive tooth plate from driving the drive gear to reset and rotate when the weight of the slide plate decreases. This avoids the phenomenon of conflict in the kinetic energy of the device. The drive gear is set to a one-way drive connection, which can prevent the drive gear from rotating when the drive tooth plate resets, thus avoiding the waste of energy. In the initial state, the drive tooth plate and the drive gear are not meshed, and the top is a bare plate. The drive shaft can store energy again through other means.

[0022] 6. When the pressure plate melts and descends, it will cause the pressure plate to drive the stretching line, which will stretch the card plate inside the second card box and simultaneously stretch the release line, so that the driving cylinder and the push shaft are no longer stuck together, which facilitates the reset and rotation of the push shaft. At this time, the bidirectional screw drives the push plate to push the electroslag ingot into the box. The card plate inside the second card box resets slowly, which facilitates the rotation of the bidirectional screw. This device can automatically push materials and automatically feed them after the electroslag block is melted, forming a linkage effect with the melting of the electroslag, realizing automated feeding and automatic reset after feeding.

[0025] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0026] like Figure 1-2 As shown, this invention discloses a gas-protected electroslag remelting device and process, including a base 1, a drive shaft 4, a driving shaft 5, a feed box 6, a push shaft 8, and a feeding box 9. A consumable electrode 2 is fixedly installed on the top of the base 1. The consumable electrode 2 has a cavity inside. A rotating wheel 3 is installed on the side wall of the consumable electrode 2. The rotating wheel 3 is drivenly connected to the drive shaft 4. The drive shaft 4 is drivenly connected to the driving shaft 5. The driving shaft 5 is rotatably connected inside the feed box 6. The feed box 6 is fixedly installed on the side wall of the consumable electrode 2. Figure 9As shown, a sliding plate 7 is slidably connected inside the feed box 6. The sliding plate 7 is driven by the drive shaft 5, and one end of the drive shaft 5 is driven by the push shaft 8. The push shaft 8 is rotatably connected inside the feed box 9, which is fixedly installed on the side wall of the feed box 6 away from the consumable electrode 2. The device, through the setting of the rotating wheel 3, enables the device to drive the electroslag ingot during melting, ensuring uniform heating of the electroslag ingot and melting the electroslag more quickly, avoiding the phenomenon of slow melting caused by uneven heating. At the same time, through the setting of the feed box 6, the device can convert the gravity of the electroslag when it enters into power for storage, thereby driving the device to operate without additional power, realizing automatic driving of the rotating wheel 3 to ensure uniform heating.

[0027] like Figure 3-4 As shown, a pressure plate 10 is slidably connected inside the consumable electrode 2. A downward pressure spring 11 is installed on the top of the pressure plate 10, and the top of the downward pressure spring 11 is fixedly connected to the inner top wall of the consumable electrode 2. The top of the pressure plate 10 is fixedly connected to one end of the tension wire 12. Multiple leakage holes 13 are provided on the inner bottom wall of the consumable electrode 2. A gas box 14 is installed on the bottom wall of the inner bottom wall of the consumable electrode 2. A sealing cover 15 is slidably connected to one side wall of the consumable electrode 2, and a sealing spring 16 is installed on the top of the sealing cover 15. The top of the sealing spring 16 is fixedly connected to the top of the side wall of the consumable electrode 2. A top plate 17 is installed on one side wall of the sealing cover 15, and the top plate 17 is set obliquely upward. A stop block 18 is fixedly installed on the other side wall of the sealing cover 15, and the stop block 18 abuts against the bottom of one side of the pressure plate 10. A sealing groove 19 is opened on one side of the inner bottom wall of the consumable electrode 2, and the sealing groove 19 matches the bottom of the sealing cover 15. A rotating ring 20 is rotatably connected to the bottom of the pressure plate 10. In the initial state, an electroslag block is placed in and melted. At this time, the sealing... Spring 16 presses down against the sealing cover 15, causing the sealing cover 15 to descend. The bottom of the sealing cover 15 seals with the sealing groove 19, and the interior of the consumable electrode 2 is sealed. When the electroslag block needs to be fed in again, the side wall of the electroslag block will abut against the top plate 17, causing the top plate 17 to move the sealing cover 15 upward. When the sealing cover 15 moves upward, the stop block 18 drives the pressure plate 10 to move synchronously. After feeding in, the melting process begins. The rotating wheel 3 drives the electroslag block to rotate, and the pressure plate 10... The electroslag block is pressed down, and the molten liquid flows out through the drain hole 13. The gas box 14 sprays out inert gas to isolate the air. The top plate 17 and the sealing cover 15 of this device can automatically seal the inside of the consumable electrode 2 to prevent the air from entering. At the same time, when feeding, it can drive the pressure plate 10 to move upward synchronously. When the molten electroslag flows into the base 1, it can automatically open and spray out gas to further isolate the air and avoid secondary oxidation of the electroslag, which would result in high oxygen content and impurity content in the steel.

[0028] like Figure 3-5 As shown, the drive shaft 4 is rotatably connected to one side wall of the consumable electrode 2. A first drive bevel gear 21 is installed on the outer wall of one end of the drive shaft 4. The first drive bevel gear 21 is meshed with a second drive bevel gear 22. The second drive bevel gear 22 is installed on the outer wall of the slide cylinder 23. The slide cylinder 23 is slidably connected to the outer wall of the rotating shaft 24. The rotating shaft 24 is rotatably connected to the inside of the consumable electrode 2. A first spiral spring 25 is installed on the outer wall of one end of the rotating shaft 24. The other end of the first spiral spring 25 is fixedly connected to the side wall of the consumable electrode 2. A drive cylinder 26 is unidirectionally driven on the outer wall of the other end of the rotating shaft 24. A first rotating bevel gear 27 is slidably installed on the outer wall of the drive cylinder 26. The second rotating bevel gear 28 is engaged with the central shaft 29, which is mounted on the outer wall of the central shaft 29. The central shaft 29 is fixedly mounted at the axis of the rotating wheel 3. A top plate 30 is mounted on the top of the central shaft 29 via a first bearing ring. The side wall of the top plate 30 is connected to a second bearing ring, which is mounted on the outer wall of the slide cylinder 23. The lower part of the central shaft 29 is fixedly connected to one end of a compression spring 31 via a third bearing ring. The other end of the compression spring 31 is fixedly connected to the inner wall of the self-consuming electrode 2. The outer wall of the rotating shaft 24 is engaged with the first card box 32. A pressing box 33 is mounted on the outer wall of the first card box 32, and the pressing box 33 abuts against one end of the top plate 30. When the drive shaft 4 rotates forward, this... Because the rotating shaft 24 and the drive cylinder 26 are connected in a one-way drive, the drive shaft 4 drives the rotating shaft 24 to rotate forward, while the drive cylinder 26 does not rotate accordingly. The first spiral spring 25 is compressed and is in an energy storage state. When the material is pushed, the material will abut against the outer wall of the rotating wheel 3, compressing the spring 31. At the same time, the top plate 30 abuts against the pressing box 33, and the top plate 30 pushes the slide cylinder 23. A limit switch is installed between the slide cylinder 23 and the rotating shaft 24. At this time, the second drive bevel gear 22 disengages from the drive shaft 4, and the rotating shaft 24 resets and rotates under the action of the first spiral spring 25, while driving the drive cylinder 26 to rotate. Under the action of the central shaft 29, the rotating wheel 3 drives the electroslag block to rotate. The rotating wheel 3 of this device is initially positioned outside the consumable electrode 2. When the material is pushed, it slides against the rotating wheel 3, facilitating contact with the electroslag block. This ensures that the rotating wheel 3 is always in contact with the outer wall of the electroslag block, preventing the rotating wheel 3 from failing to rotate the electroslag block after melting and the diameter of the block decreasing. This ensures that the rotating wheel 3 can always rotate the electroslag block, regardless of whether the diameter of the electroslag block decreases too quickly or too slowly. At the same time, the lower position of the rotating wheel 3 avoids conflict with the downward pressure of the pressure plate 10. When the rotating wheel 3 rotates the electroslag block, it also cleans its bottom, preventing the electroslag solution from sticking together.

[0029] like Figure 6As shown, a groove 34 is provided inside the rotating shaft 24, and an extension plate 35 is slidably connected inside the groove 34. One end of the extension plate 35 is triangular in shape, and an extension spring 36 is fixedly installed at one end of the extension plate 35 inside the groove 34. The other end of the extension spring 36 is fixedly connected to the inner wall of the groove 34. An inclined groove 37 is provided on the inner wall of the drive cylinder 26, and the inclined groove 37 matches the extension plate 35. When the drive shaft 4 drives the rotating shaft 24 to rotate in the forward direction, the inclined surface of the extension plate 35 is opposite to the inclined surface of the inclined groove 37, so that the extension plate 35 retracts into the groove 34. At this time, the rotating shaft 24 rotates, but does not drive the drive cylinder 26 to rotate. When the rotating shaft 24 returns to its original position, the straight surface of the extension plate 35 is opposite to the straight surface of the inclined groove 37, and the rotating shaft 24 can drive the drive cylinder 26 to rotate.

[0030] like Figure 7 As shown, an arc block 39 is fixedly installed on the outer wall of the rotating shaft 24. A card plate 38 is slidably connected inside the first card box 32. One side of one end of the card plate 38 is provided with an arc surface, and the other end is provided with a straight surface. The arc surface of the card plate 38 matches the arc block 39. The other end of the card plate 38 is fixedly connected to one end of the snap-fit ​​spring 40. The other end of the snap-fit ​​spring 40 is fixedly connected to the inner wall of the first card box 32. The other end of the card plate 38 is also fixedly connected to one end of the drive line 41. When the drive shaft 4 of this device drives the rotating shaft 24 to rotate, the arc surface of the arc block 39 will be opposite to the arc surface of the card plate 38. The card plate 38 is compressed and contracts, which facilitates the energy storage of the rotating shaft 24. When it is not released autonomously, the first card box 32 can play a restrictive role to avoid energy loss. After the drive line 41 is stretched, the rotating shaft 24 will be reset and rotated under the action of the first spiral spring 25, realizing the operation of the device. At the same time, this device can store energy manually or through a motor connected to the drive shaft 4, etc., to realize electrical energy storage.

[0031] like Figure 8As shown, one end of the drive cable 41 passes through the first card box 32 and is fixedly connected to the inside of the pressing box 33. A pressing block 42 is slidably connected inside the pressing box 33. The bottom of the pressing block 42 abuts against the outer wall of the drive cable 41. One side of the bottom of the pressing block 42 is fixedly connected to one end of a pressing spring 43, and the other end of the pressing spring 43 is fixedly connected to the inner bottom wall of the pressing box 33. In its initial state, under the action of the pressing spring 43, the pressing block 42 will not abut against the drive cable 41. When the rotating wheel 3 is pushed, the abutment plate 30 will push the pressing block 42, causing... When the pressing block 42 is pressed, the drive line 41 is stretched, the card plate 38 inside the first card box 32 is stretched, and the rotating shaft 24 is reset and rotated. Through the setting of the abutment plate 30, this device can make the pressing block 42 abut against the pressing block 42 after the rotating wheel 3 pushes it, so that the pressing block 42 can reset the rotating shaft 24. At the same time, the second drive bevel tooth 22 disengages from the first drive bevel tooth 21, automatically realizing the reset rotation of this device, so that this device can start automatically and achieve the effect of linkage with the pushed material without the need for additional operation.

[0032] like Figure 9 As shown, a drive gear plate 44 is fixedly installed at the bottom of the slide plate 7. The drive gear plate 44 is meshed with the drive gear 45. The drive gear 45 is unidirectionally driven and connected to the outer wall of the drive shaft 5. A discharge port 46 is opened on the side wall of the feed box 6. The discharge port 46 is flush with the feed of the consumable electrode 2. The bottom of the slide plate 7 is fixedly connected to one end of the return spring 47. The other end of the return spring 47 is fixedly connected to the inner bottom wall of the feed box 6. A limit box 48 is installed on the inner bottom wall of the feed box 6. The limit box 48 is opposite to the drive gear plate 44. The drive shaft 5 is driven and connected to the drive shaft 4 through the first transmission belt 49. The electroslag block is first placed on the top of the slide plate 7. At this time, under the action of its own gravity, the slide plate 7 moves downward. The drive gear plate 44 drives the drive gear 45 to rotate. At this time, the drive shaft 5 drives the drive shaft 4 to rotate through the first transmission belt 49. After the slide plate 7 descends to the position flush with the discharge port 46, it reaches the limit position.

[0033] like Figure 10As shown, a first limiting block 50 is installed on the side wall of the bottom wall of the drive gear plate 44, and a second limiting block 51 is slidably connected to the inner side wall of the limiting box 48. The top of the second limiting block 51 is set as an arc surface, and the bottom is a straight surface. The second limiting block 51 matches the first limiting block 50. The outer wall of the second limiting block 51 is fixedly connected to one end of the limiting spring 52, and the other end of the limiting spring 52 is fixedly connected to the inner side wall of the limiting box 48. The end of the second limiting block 51 away from the arc surface is fixedly connected to one end of the reset line 53. One end of the reset line 53 is located outside the base 1. After the drive gear plate 44 descends to the limit position, it will cause the drive gear plate to... 44 descends into the interior of the limiting box 48. At this time, the first limiting block 50 and the second limiting block 51 abut against each other. The second limiting block 51 acts as a locking and limiting device for the drive gear plate 44, preventing the drive gear plate 44 from resetting and rotating when the gravity of the slide plate 7 decreases. This avoids conflicts in the kinetic energy of the device. The drive gear 45 is set to a one-way drive connection, which can prevent the drive gear 45 from rotating when the drive gear plate 44 resets, thus avoiding energy waste. In the initial state, the drive gear plate 44 and the drive gear 45 are not meshed, and the top is a bare plate. The drive shaft 5 can store energy again in other ways.

[0034] like Figure 11 As shown, the drive shaft 5 is driven and connected to the push shaft 8 via the second transmission belt 54. A second spiral spring 55 is installed on the outer wall of one end of the push shaft 8. The other end of the second spiral spring 55 is fixedly connected to the inner side wall of the feeding box 9. A first connecting bevel tooth 56 is installed on the outer wall of the push shaft 8. The first connecting bevel tooth 56 and the second connecting bevel tooth 57 are meshed and connected. The second connecting bevel tooth 57 is installed on the outer wall of one end of the bidirectional lead screw 58. A threaded block 60 is threadedly connected to the outer wall of the bidirectional lead screw 58. A push plate 59 is installed on the outer wall of the threaded block 60.

[0035] like Figure 12As shown, the outer wall of the push shaft 8 is engaged with the second card box 61. The connecting line 62 inside the second card box 61 is connected to the tension line 12. A drive cylinder 63 is installed on the outer wall of the push shaft 8 and is connected to the second transmission belt 54. A limit strip 64 is slidably connected to the outer wall of the push shaft 8. One end of the limit strip 64 is connected to the inner ring of the first bearing ring 65. One end of the first bearing ring 65 is connected to the second bearing ring 67 through a tension spring 66. The outer wall of the first bearing ring 65 is fixedly connected to one end of the release line 68, and the other end of the release line 68 is connected to one end of the tension line 12. When the pressure plate 10 melts and descends... This will cause the pressure plate 10 to drive the stretching line 12, which will stretch the card plate inside the second card box 61 and stretch the release line 68, so that the driving cylinder 63 and the push shaft 8 are no longer stuck together, which facilitates the reset and rotation of the push shaft 8. At this time, the bidirectional screw 58 drives the push plate 59 to push the electroslag ingot into the box. The card plate inside the second card box 61 resets slowly, which facilitates the rotation of the bidirectional screw 58. This device can automatically push materials and automatically feed them after the electroslag block is melted, forming a linkage effect with the melting of electroslag, realizing automated feeding, automatic reset after feeding, and the push shaft can be manually operated.
