Description

Technical Field

[0001] The present invention relates to the technical field of descaling of continuous casting billets, and particularly relates to a continuous casting billet descaling device and a continuous casting billet descaling method. Background Art

[0002] A continuous casting billet is a product obtained by casting molten steel from a steelmaking furnace through a continuous caster. When the continuous casting billet is oxidized at a high temperature, a dense scale will form on its surface. If this scale cannot be removed before rolling, during the rolling process, they will be pressed into the surface of the steel plate by the rolling rolls, and concave and convex marks will be formed on the surface of the finished product after annealing, straightening and falling off, seriously affecting the surface quality of the product.

[0003] When the existing continuous casting billets are descaled, the mechanical force of high-pressure water is usually used for impact. However, the water remaining during the descaling process will quickly cause the surface of the rolled material to be oxidized again. At the same time, using high-pressure water for descaling will cause a sharp drop in the surface temperature of the casting billet. At the same time, a boiling film will form on the surface of the continuous casting billet, thereby greatly weakening the effect of high-pressure water descaling. In addition, some will use the method of grinding to descale the continuous casting billet, but this method requires frequent replacement of the friction surface of the continuous casting billet and cannot grind the entire surface at one time, so the descaling is more troublesome and time-consuming.

[0004] Based on this, we propose a continuous casting billet descaling device and a continuous casting billet descaling method. Summary of the Invention

One end of each of the two rotating shafts penetrates through the side wall of the vertical block and is fixedly connected to a driven wheel. The driving wheel and the driven wheel on the same side are connected by a synchronous belt.

[0008] Preferably, four mounting plates are fixedly connected to the side wall of each mounting frame through brackets. A T-shaped rod is slidably connected to the side wall of each mounting plate. One end of the T-shaped rod is fixedly connected to a first friction plate. A first spring is sleeved on the side wall of the T-shaped rod.

[0009] Preferably, two rectangular blocks are symmetrically and fixedly connected to the upper end of the base. Grooves are formed in the side walls of the two rectangular blocks. A friction block is slidably connected to the inner wall of the groove. A plurality of second springs are fixedly connected between the inner wall of the groove and the friction block.

[0010] Preferably, two sliding grooves are symmetrically formed at both ends of the vertical plate. A friction arc block is slidably connected to the inner wall of each of the two sliding grooves.

[0012] Preferably, a friction mechanism is installed on the clamping plate. The friction mechanism includes a cavity formed in the clamping plate. Two magnetic plates are symmetrically and slidably connected to the inner wall of the cavity. An L-shaped rod is fixedly connected to the side wall of each of the two magnetic plates. The other end of the L-shaped rod is fixedly connected to the second friction plate.

[0013] Preferably, the friction mechanism further includes an electromagnet fixedly connected to the inner wall of the cavity. Two fourth springs are symmetrically and fixedly connected to the side wall of the electromagnet.

By setting a friction mechanism, when the clamping block moves up and down, the clamping block will intermittently contact the conductive plate. At this time, the electromagnet will be intermittently energized. When the electromagnet is energized, a magnetic repulsive force will be generated to push the two magnetic plates to slide. When the electromagnet is de-energized, the magnetic plates will reset under the action of the fourth spring, so that the magnetic plates move up and down reciprocally, driving the two L-shaped rods to move up and down reciprocally, driving the two second friction plates to move up and down reciprocally, making the second friction plate generate friction with the side surface of the continuous casting billet for descaling, avoiding the part of the contact between the clamping plate and the continuous casting billet from not being descaled and reducing the descaling effect of the continuous casting billet; 3. By setting impellers and a dust discharge pipe, during the descaling process, the rotation of the rotating shaft will drive multiple impellers to rotate, generating a suction force. Therefore, the scale rubbed off during the descaling process will be sucked into the dust suction groove, and then the scale will be discharged through the dust discharge pipe into the external collection container, avoiding the scale rubbed off from flying randomly into the working environment, causing pollution to the working environment, and being able to recycle the scale, avoiding waste of resources.

The descaling mechanism includes two mounting brackets 5 symmetrically and fixedly connected to the upper end of the base 1. Vertical grooves 6 and horizontal grooves 7 are formed in the side walls of both mounting brackets 5. A clamping block 8 is slidably connected to the inner wall of the vertical groove 6, and a mounting block 9 is slidably connected to the inner wall of the horizontal groove 7. A vertical plate 10 is fixedly connected to the side walls of the two mounting blocks 9 close to each other. Among them, a connecting rod 11 is rotatably connected to the side walls of the clamping block 8 and the mounting block 9 on the same side. A first gear 12 is fixedly connected to the side wall of the connecting rod 11. Two vertical blocks 13 are symmetrically and fixedly connected to the upper end of the base 1. Dust suction grooves 38 are formed in the side walls of both vertical blocks 13. A rotating shaft 14 is rotatably connected to the inner wall of the dust suction groove 38. A second gear 15 is fixedly connected to the side wall of the rotating shaft 14. The first gear 12 is meshed with the second gear 15; A driving mechanism is installed on the base 1.

[0021] The driving mechanism includes a motor 17 fixedly connected to the side wall of the base 1 through a bracket. A rotating rod 16 is rotatably connected to the side walls of the two vertical blocks 13 close to each other. Both ends of the rotating rod 16 penetrate through the side walls of the vertical blocks 13. The output end of the motor 17 is fixedly connected to the rotating rod 16. Two driving wheels 18 are symmetrically and fixedly connected to the side wall of the rotating rod 16. One end of each of the two rotating shafts 14 penetrates through the side wall of the vertical block 13 and is fixedly connected to a driven wheel 19. Among them, the driving wheel 18 and the driven wheel 19 on the same side are connected by a synchronous belt.

[0022] Four mounting plates 20 are fixedly connected to the side wall of each mounting bracket 5 through brackets. A T-shaped rod 21 is slidably connected to the side wall of each mounting plate 20. A first friction plate 2 is fixedly connected to one end of the T-shaped rod 21. A first spring 22 is sleeved on the side wall of the T-shaped rod 21. Both ends of the first spring 22 are fixedly connected to the side walls of the T-shaped rod 21 and the mounting plate 20 respectively.

[0023] Two rectangular blocks 23 are symmetrically and fixedly connected to the upper end of the base 1. Grooves 24 are formed in the side walls of both rectangular blocks 23. A friction block 3 is slidably connected to the inner wall of the groove 24. A plurality of second springs 25 are fixedly connected between the inner wall of the groove 24 and the friction block 3.

[0024] Two sliding grooves 26 are symmetrically formed at both ends of the vertical plate 10. A friction arc block 4 is slidably connected to the inner wall of each of the two sliding grooves 26. A plurality of third springs 27 are fixedly connected between the inner wall of the sliding groove 26 and the friction arc block 4.

[0025] A fixing mechanism is installed on the clamping block 8. The fixing mechanism includes an electric push rod 28 fixedly connected to the side wall of the clamping block 8. A clamping plate 29 is fixedly connected to the movable end of the electric push rod 28. An installation groove 30 is formed in the side wall of the clamping plate 29. Two second friction plates 31 are symmetrically and slidably connected to the inner wall of the installation groove 30.

[0026] Further, the driving motor 17 rotates, driving the rotating rod 16 to rotate, and then driving the two driving wheels 18 to rotate synchronously, thereby driving the two driven wheels 19 to rotate synchronously. Finally, the two rotating shafts 14 are driven to rotate synchronously, driving the two second gears 15 to rotate. Since the first gear 12 meshes with the second gear 15, under the limiting action of the vertical groove 6 and the horizontal groove 7, the second gear 15 will perform a circular motion with the center of the first gear 12 as the center, thereby driving the connecting rod 11 to rotate together with the first gear 12. At this time, the clamping block 8 will reciprocate up and down on the inner wall of the vertical groove 6, and the mounting block 9 will reciprocate horizontally on the inner wall of the horizontal groove 7. Moreover, the sliding between the clamping block 8 and the mounting block 9 will cause mutual dislocation. The reciprocating up and down movement of the clamping block 8 will drive the continuously cast billet clamped and fixed to reciprocate up and down, so that friction is generated between the two sides of the continuously cast billet and the first friction plate 2, and friction is generated between the front and rear two surfaces of the continuously cast billet and the two friction blocks 3 respectively. Furthermore, descaling can be performed on the two sides and the front and rear two surfaces of the continuously cast billet at the same time. The reciprocating horizontal movement of the mounting block 9 will drive the friction arc block 4 to reciprocate horizontally. When the continuously cast billet reciprocates up and down, the upper and lower two surfaces of the continuously cast billet will intermittently contact the upper and lower two friction arc blocks 4, so that the friction arc block 4 can perform friction descaling on the upper and lower two surfaces of the continuously cast billet. Using this friction method for descaling, compared with high-pressure water impact, the continuously cast billet will not be oxidized again, the descaling effect is better, and descaling can be performed on the six surfaces of the continuously cast billet at the same time, and the descaling efficiency is higher.

[0027] A friction mechanism is installed on the clamping plate 29. The friction mechanism includes a cavity 32 opened in the clamping plate 29. Two magnetic plates 33 are symmetrically and slidably connected to the inner wall of the cavity 32. L-shaped rods 34 are fixedly connected to the side walls of the two magnetic plates 33, and the other ends of the L-shaped rods 34 are fixedly connected to the second friction plate 31.

[0028] The friction mechanism further includes an electromagnet 35 fixedly connected to the inner wall of the cavity 32. Two fourth springs 36 are symmetrically fixedly connected to the side wall of the electromagnet 35, and the other ends of the two fourth springs 36 are respectively fixedly connected to the two magnetic plates 33. A conductive plate 37 is embedded in the inner wall of one of the vertical grooves 6. The clamping block 8 is made of a conductive material. The electromagnet 35, the conductive plate 37, the clamping block 8 and an external power supply are electrically connected by wires.

[0029] Further, when the clamping block 8 moves up and down, the clamping block 8 intermittently contacts the conductive plate 37. At this time, the electromagnet 35 is intermittently powered on. When the electromagnet 35 is powered on, a magnetic repulsive force is generated to push the two magnetic plates 33 to slide. When the electromagnet 35 is powered off, the magnetic plates 33 are reset under the action of the fourth spring 36, so that the magnetic plates 33 move up and down reciprocally, driving the two L-shaped rods 34 to move up and down reciprocally, driving the two second friction plates 31 to move up and down reciprocally, causing the second friction plates 31 to generate friction with the side surface of the continuous casting billet for descaling, avoiding the contact part between the clamping plate 29 and the continuous casting billet from not being descaled and reducing the descaling effect of the continuous casting billet.

[0030] A plurality of impellers 39 are fixedly connected to the side wall of the dust suction groove 38 where the rotating shaft 14 is located, and a dust discharge pipe 40 is fixedly connected to the inner wall of the dust suction groove 38.

[0031] Further, during the descaling process, the rotation of the rotating shaft 14 drives the plurality of impellers 39 to rotate, thereby generating a suction force. Therefore, the scale removed during the descaling process is drawn into the dust suction groove 38, and then the scale is discharged into an external collection container through the dust discharge pipe 40, avoiding the scale removed by friction from flying randomly into the working environment and causing environmental pollution of the working environment, and also being able to recycle the scale to avoid waste of resources.

[0032] A method for descaling a continuous casting billet includes the following steps: S1. First, place the continuous casting billet between the two clamping plates 29, and then drive the electric push rod 28 to extend, driving the clamping plates 29 to move to clamp and fix the continuous casting billet; S2. Then drive the motor 17 so that the clamping block 8 moves in the vertical direction, while the mounting block 9 moves in the horizontal direction, so that each surface of the continuous casting billet generates friction with the first friction plate 2, the friction block 3, and the friction arc block 4 respectively, removing the scale on the surface of the continuous casting billet to achieve the purpose of descaling; S3. During the descaling process, the plurality of impellers 39 rotate to generate a suction force, and the scale removed is then sucked into the dust suction groove 38, and then the scale is discharged into an external collection container through the dust discharge pipe 40 for collection; S4. After the descaling is completed, the continuous casting billet is removed and subjected to subsequent rolling.

[0033] In the present invention, first drive the electric push rod 28 to extend, driving the clamping plates 29 to approach each other to clamp and fix the continuous casting billet. At this time, the first friction plate 2 fits with the two side surfaces of the continuous casting billet under the action of the first spring 22, and the two friction blocks 3 fit with the front and rear surfaces of the continuous casting billet under the action of the second spring 25.

[0034] Next, the driving motor 17 rotates, driving the rotating rod 16 to rotate, and then driving the two driving wheels 18 to rotate synchronously, thereby driving the two driven wheels 19 to rotate synchronously, and finally driving the two rotating shafts 14 to rotate synchronously, driving the two second gears 15 to rotate. Since the first gear 12 meshes with the second gear 15, under the limiting action of the vertical groove 6 and the horizontal groove 7, the second gear 15 will perform a circular motion with the center of the first gear 12 as the center, thereby driving the connecting rod 11 to rotate together with the first gear 12. At this time, the clamping block 8 will reciprocate up and down along the inner wall of the vertical groove 6, and the mounting block 9 will reciprocate horizontally along the inner wall of the horizontal groove 7, and the sliding between the clamping block 8 and the mounting block 9 will cause mutual dislocation. The reciprocating up and down movement of the clamping block 8 will drive the continuously cast billet clamped and fixed to reciprocate up and down, so that friction is generated between the two sides of the continuously cast billet and the first friction plate 2, and friction is generated between the front and rear two surfaces of the continuously cast billet and the two friction blocks 3 respectively. Furthermore, descaling can be performed on the two sides and the front and rear two surfaces of the continuously cast billet at the same time. The reciprocating horizontal movement of the mounting block 9 will drive the friction arc block 4 to reciprocate horizontally. When the continuously cast billet reciprocates up and down, the upper and lower two surfaces of the continuously cast billet will intermittently contact the upper and lower two friction arc blocks 4, so that the friction arc block 4 can perform friction descaling on the upper and lower two surfaces of the continuously cast billet. Using this friction method for descaling, compared with high-pressure water impact, the continuously cast billet will not be oxidized again, the descaling effect is better, and descaling can be performed on the six surfaces of the continuously cast billet at the same time, and the descaling efficiency is higher.

[0035] When the clamping block 8 moves up and down, the clamping block 8 will intermittently contact the conductive plate 37. At this time, the electromagnet 35 will be intermittently energized. When the electromagnet 35 is energized, a magnetic repulsive force will be generated to push the two magnetic plates 33 to slide. When the electromagnet 35 is de-energized, the magnetic plate 33 will reset under the action of the fourth spring 36, so that the magnetic plate 33 reciprocates up and down, thereby driving the two L-shaped rods 34 to reciprocate up and down, driving the two second friction plates 31 to reciprocate up and down, so that the second friction plate 31 generates friction with the side surface of the continuously cast billet for descaling, avoiding the part of the clamping plate 29 in contact with the continuously cast billet from being unable to be descaled and reducing the descaling effect of the continuously cast billet.

[0036] In addition, during the descaling process, the rotation of the rotating shaft 14 will drive a plurality of impellers 39 to rotate, thereby generating a suction force. Therefore, the scale removed by friction during the descaling process will be sucked into the dust suction groove 38, and then the scale will be discharged into an external collection container through the dust discharge pipe 40, avoiding the scale removed by friction from flying randomly into the working environment and causing pollution to the working environment, and being able to recycle the scale removed by friction to avoid waste of resources.

[0037] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.

Then drive the motor (17) so that the clamping block (8) moves in the vertical direction, while the mounting block (9) moves in the horizontal direction, so that the surfaces of the continuous casting billet respectively generate friction with the first friction plate (2), the friction block (3) and the friction arc block (4), removing the scale on the surface of the continuous casting billet to achieve the purpose of descaling. S3. During descaling, the plurality of impellers (39) will rotate to generate a suction force, and the removed scale will be sucked into the dust suction groove (38), and then the scale will be discharged into an external collection container through the dust discharge pipe (40) for collection. S4. After descaling, take down the continuous casting billet and perform subsequent rolling on it.
