Description

Technical Field

[0001] The present invention relates to the technical field of alloys, and particularly to a refining treatment method and device for the production of cold heading steel wire rods. Background Art

[0002] Cold heading steel wire rods generally belong to the category of low and medium carbon high-quality carbon structural steels and high-quality alloy structural steels, and are mainly used for cold heading forming to manufacture various mechanical standard parts and fasteners. In recent years, with the continuous development of materials science, amorphous alloys, as a new type of material, have gradually come into people's view. Amorphous alloys have excellent mechanical properties, corrosion resistance, soft magnetic properties, etc. In the field of cold heading steel wire rod production, it has been found that introducing appropriate amounts of amorphous alloy elements into cold heading steel is expected to further optimize its properties.

[0003] After introducing amorphous alloy elements, the influence on the structure of the wire rod becomes more complex, and how to achieve precise control of the structure under the new material system becomes particularly crucial. Therefore, structure control is crucial in the production of cold heading steel wire rods. During actual production, the refining furnace is mainly relied on to adjust process parameters such as rolling temperature, wire laying temperature, and cooling rate to effectively control the structure of the wire rod.

[0004] However, the addition of amorphous alloys may change the properties of the molten steel, requiring higher timeliness and precision in the refining process. Most refining furnaces do not have an advanced automated opening system for amorphous alloy elements and cannot achieve one-key operation. Workers need to manually complete a series of actions such as unlocking, lifting, and moving the furnace cover in sequence. A slight oversight during the operation may lead to operation errors, further prolonging the opening time, affecting the fusion effect of amorphous alloy elements and cold heading steel, and unable to fully exert the potential of amorphous alloys to improve the properties of cold heading steel wire rods. Therefore, a refining treatment method and device for the production of cold heading steel wire rods are proposed to solve the above problems. Summary of the Invention

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] Referring to Figures 1 to 3 , an embodiment provided by the present invention: A refining treatment method for cold heading steel wire rod production, characterized by comprising the following steps: 1: Refining, feeding materials such as amorphous alloy into the refining treatment device, and then smelting to obtain continuous casting billets according to the required chemical composition ratio.

[0017] S2: Continuous casting. The continuous casting billet is fully heated at a temperature of 1070°C - 1110°C, and the descaling treatment is carried out on the heated continuous casting billet.

[0018] S3: Rolling. Rough rolling is carried out using a frame rolling mill. The pass grooves of the rolling mill are alternately arranged with planes and vertical surfaces. The inlet temperature of the rough rolling is controlled at 930°C - 950°C.

[0019] The refining treatment device for producing cold heading steel wire rod includes a ladle 1, a heat preservation cover 5 and a moving bottom plate 27. The ladle 1 is made of high-strength materials to withstand the pressure brought by high temperature and chemical reactions. A refining bladder 2 is fixedly connected inside the ladle 1. The refining bladder 2 is an independent space inside the ladle 1 for containing molten steel and carrying out refining treatment. The top of the refining bladder 2 is flush with the top of the ladle 1.

[0020] Reference Figure 2 , a heating pipe 3 is fixedly connected to the outside of the ladle 1. The heating pipe 3 uses resistance heating during the refining process to continuously heat the molten steel in the refining bladder 2, enabling the molten steel to quickly fuse with materials such as amorphous alloys, keeping the temperature of the molten steel within an appropriate range, and ensuring the smooth progress of the refining reaction. A control end 4 is arranged on the right side of the outside of the heating pipe 3. The control end 4 is the operation center of the refining treatment device, responsible for controlling the heating temperature of the heating pipe 3, the telescopic movement of the hydraulic cylinder 8, and the rotation of the motor 32.

[0021] Reference Figure 7 , a liquid outlet pipe 6 is arranged on one side of the top of the ladle 1 close to the hydraulic cylinder 8. The top of the liquid outlet pipe 6 is fixedly connected to the bottom of the refining bladder 2. The liquid outlet pipe 6 is a pipe that penetrates and connects the ladle 1 and the refining bladder 2 for discharging the refined molten steel. An argon pipe 7 is arranged on one side of the bottom of the ladle 1 close to the hydraulic cylinder 8. The argon pipe 7 is externally connected to argon, and the argon is sent into the bottom breathable bricks of the ladle 1 and the refining bladder 2 to achieve inflation inside the refining bladder 2, causing the argon to drive the bubbles in the molten steel to rise upward, thereby driving the agitation of the molten steel.

[0022] Reference Figure 3 , Figure 4 , a hydraulic cylinder 8 is fixedly connected to the outside of the ladle 1. The hydraulic cylinder 8 is fixed to the outside of the ladle 1 by bolts. The driving end of the hydraulic cylinder 8 is rotatably connected to a steel rod 9. The driving end of the hydraulic cylinder 8 extends or retracts to push the steel rod 9 to move up and down. The top of the steel rod 9 is fixedly connected to one side of the heat preservation cover 5 close to the hydraulic cylinder 8. During the refining process, the heat preservation cover 5 closely covers the outside of the ladle 1 to form a heat insulation layer, reducing heat transfer and loss. When the steel rod 9 moves up and down, the heat preservation cover 5 fixed by the steel rod 9 will move along with the steel rod 9.

[0023] Reference Figure 5, a sleeve 10 is fixedly connected to the outer bottom end of the steel rod 9. The sleeve 10 is fixed at the bottom end of the steel rod 9. When the steel rod 9 is driven by the hydraulic cylinder 8 to move up and down, the steel rod 9 will also drive the sleeve 10 to rise synchronously. One end of the sleeve 10 away from the ladle 1 is fixedly connected with a limiting roller 11. The limiting roller 11 is perpendicular to the outside of the sleeve 10 and is fixed at the middle position on the side of the sleeve 10 away from the ladle 1.

[0024] A connecting disc 12 is fixedly connected to the outer top end of the steel rod 9. The connecting disc 12 is disc-shaped and is welded at the middle position of the steel rod 9. A connecting roller 13 is fixedly connected to the rear side of the connecting disc 12. The connecting roller 13 is parallel to the ladle 1 and is welded to the side of the connecting disc 12. A limiting sleeve 14 is fixedly connected to the outside of the heating pipe 3. The limiting sleeve 14 is sleeved on the outside of the steel rod 9. An inverted L-shaped arc-shaped chute is provided on the side of the limiting sleeve 14 away from the ladle 1. The outside of the limiting roller 11 is slidably connected to the outside of the limiting sleeve 14. The outside of the sleeve 10 is slidably connected to the inner wall of the limiting sleeve 14. During the process that the sleeve 10 moves upward synchronously with the steel rod 9, the limiting roller 11 protruding from the middle of the sleeve 10 will slide along the L-shaped chute on the inner wall of the limiting sleeve 14.

[0025] Reference Figure 6 , a rack bar 15 is fixedly connected to the outside of the hydraulic cylinder 8. The bottom end of the rack bar 15 is fixed to the top end of the housing of the hydraulic cylinder 8 by bolts, and the top teeth of the rack bar 15 are higher than the heat insulation cover 5. A support plate 16 is fixedly connected to the side of the heating pipe 3 close to the hydraulic cylinder 8. The support plate 16 is a flat component made of high-strength steel plate.

[0026] A shrinkage component for slag filtering is arranged at the top ends of the support plate 16 and the heat insulation cover 5. The shrinkage component includes an L-shaped rotating plate 17. The bottom end of the L-shaped rotating plate 17 is rotatably connected to the top end of the support plate 16. The bottom end of the L-shaped rotating plate 17 is rotatably connected to the top end of the support plate 16, and the connection method adopts a pin shaft connection, allowing the L-shaped rotating plate 17 to rotate freely. A first driving wheel 18 is rotatably connected to the side of the L-shaped rotating plate 17 close to the hydraulic cylinder 8. The connection method between the L-shaped rotating plate 17 and the first driving wheel 18 also adopts a pin shaft connection. A connecting rod 19 is rotatably connected to the side of the first driving wheel 18 close to the hydraulic cylinder 8. The bottom end of the connecting rod 19 is connected to the surface edge position of the first driving wheel 18.

[0027] One end of the connecting rod 19 away from the first driving wheel 18 is rotatably connected to the outside of the connecting roller 13. When the connecting roller 13 rises and rotates with the connecting disc 12, the connecting roller 13 will pull the connecting rod 19 to slide along the surface of the first driving wheel 18. The sliding of the connecting rod 19 drives the rotation of the first driving wheel 18, thus realizing the transmission of power and enabling the tungsten alloy rope 24 outside the first driving wheel 18 to be tightened as the first driving wheel 18 rotates.

[0028] Reference Figure 8 , Figure 9, a support shaft block 20 is fixedly connected to the top end of the heat preservation cover 5. The support shaft block 20 is located at the top edge of the heat preservation cover 5 and is composed of a U-shaped block and a rotating shaft. A second driving wheel 21 and a driven gear 22 are rotatably connected to the middle of the support shaft block 20. The second driving wheel 21 and the driven gear 22 are fixed on the rotating shaft in the support shaft block 20. Through the connection of the rotating shaft, when the driven gear 22 rotates, the second driving wheel 21 will rotate along with the driven gear 22.

[0029] The external teeth of the driven gear 22 are meshed with the teeth on the side of the rack bar 15 close to the heat preservation cover 5. A driven wheel 23 is arranged in the middle of the top end of the heat preservation cover 5. A tungsten alloy rope 24 is sleeved outside the first driving wheel 18, the second driving wheel 21 and the driven wheel 23. The bottom end of the tungsten alloy rope 24 is fixedly connected with a filter screen 25. The outer part of the filter screen 25 is slidably connected to the inner wall of the refining tank 2. The outer part of the tungsten alloy rope 24 is slidably connected to the middle of the heat preservation cover 5. When the driven gear 22 meshes and rotates with the teeth of the rack bar 15, the driven gear 22 will drive the second driving wheel 21 to rotate through the shaft of the support shaft block 20. The rotation of the second driving wheel 21 will further tighten the tungsten alloy rope 24, thereby driving the filter screen 25 to rise.

[0030] An annular pipe moving frame 26 is fixedly connected to the outside of the ladle 1. Moving wheels are arranged at the four corners of the annular pipe moving frame 26, which allows the ladle 1 to move on the top end of the moving bottom plate 27 through the moving wheels. An arc-shaped groove 28 is formed in the top end of the moving bottom plate 27. A rotating frame 29 is rotatably connected to the right side of the top end of the moving bottom plate 27. The bottom end of the side of the rotating frame 29 away from the driven worm gear 30 is slidably connected to the inner wall of the arc-shaped groove 28. The side of the rotating frame 29 close to the protective cover 31 is rotatably connected to the top end of the moving bottom plate 27. The top end of the side of the rotating frame 29 away from the protective cover 31 is rotatably connected to the middle of the bottom end of the ladle 1. When the rotating frame 29 swings, its bottom end will slide in the arc-shaped groove 28, and the arc-shaped groove 28 provides a specific trajectory for the swing of the rotating frame 29. The beneficial effect is that the arc-shaped groove 28 precisely controls the swing trajectory of the rotating frame 29, ensures the stability and accuracy of the swing of the ladle 1, and thus improves the refining effect.

[0031] A protective cover 31 is fixedly connected to the side wall of the moving bottom plate 27. The protective cover 31 is made of high-strength steel plates and has good protective performance. A motor 32 is fixedly connected to the side wall of the protective cover 31. The driving end of the motor 32 is fixedly connected with a driving half bevel gear 33. After the motor 32 is started, it will drive the driving half bevel gear 33 to rotate continuously.

[0032] A shaft roller 34 is rotatably connected to the middle of the protective cover 31. A first driven bevel gear 35 is fixedly connected to the outside of the shaft roller 34. The external teeth of the first driven bevel gear 35 are meshed with the external teeth of the driving half bevel gear 33. A second driven bevel gear 36 is fixedly connected to the middle of the outside of the shaft roller 34. The external teeth of the driving half bevel gear 33 are meshed with the external teeth of the second driven bevel gear 36. When the motor 32 drives the driving half bevel gear 33 to rotate, the half teeth on the outside of the driving half bevel gear 33 will repeatedly mesh with the first driven bevel gear 35 and the second driven bevel gear 36 whose tooth directions are in the opposite direction. This meshing drive enables the shaft roller 34 to rotate forward one week and then automatically rotate backward one week.

[0033] One end of the shaft roller 34 away from the first driven bevel gear 35 is fixedly connected with a driving worm 37. The outside of the driven worm wheel 30 is meshed with the external teeth of the driving worm 37. When the driving half bevel gear 33 meshes and rotates with the first driven bevel gear 35 and the second driven bevel gear 36, it will drive the shaft roller 34 to rotate. The rotation of the shaft roller 34 will further drive the driving worm 37 to rotate, so as to realize the swing of the driven worm wheel 30. Among them, the tooth ratio of the driving worm 37 to the driven worm wheel 30 is two to one, which is to prevent the teeth of the driven worm wheel 30 from disengaging from the driving worm 37.

[0034] Working principle: During use, the calcium-magnesium alloy cored wire is fed into the refining tank 2 of the ladle 1, and the calcium-magnesium alloy cored wire is melted into the molten steel in the refining tank 2. The heating tube 3 is controlled by the control end 4 to continuously heat the refining tank 2. At this time, an argon gas pipe 7 is externally connected so that argon gas passes through the porous plug at the top of the ladle 1 and the top of the refining tank 2, and the argon gas is filled into the refining tank 2, so that the molten steel and materials such as amorphous alloy in the refining tank 2 are slightly stirred under the drive of the argon gas. At this time, the motor 32 is started to control the driving half bevel gear 33 to rotate continuously. After the driving half bevel gear 33 rotates, the half teeth on the outside of the driving half bevel gear 33 will repeatedly mesh with the first driven bevel gear 35 and the shaft roller 34 whose tooth directions are in the opposite direction, causing the driving worm 37 fixed to the shaft roller 34 to rotate forward one week and then automatically rotate backward one week, and synchronously drive the driven worm wheel 30 to mesh with the outside of the driving worm 37 through the external teeth. At this time, due to the left and right swing of the driven worm wheel 30 meshing with the driving worm 37, the other end fixed to the rotating frame 29 drives the ladle 1 to slide on the inner wall of the arc-shaped groove 28 with the rotating frame 29 as the center. And because the other end of the driven worm wheel 30 is connected to the ladle 1, when the driven worm wheel 30 swings left and right, the rotating frame 29 will drive the refining tank 2 to swing slightly left and right, realizing that by blowing argon through the argon gas pipe 7 at the bottom of the refining tank 2 and the swing of the ladle 1 itself, the flow direction and speed of the molten steel in the refining tank 2 can be changed, so that the inclusions in the refining tank 2 and the bubbles after blowing argon increase the contact times, further improving the removal efficiency of the inclusions.

[0035] When the refining is completed, the control motor 32 is stopped, and then the hydraulic cylinder 8 is started to expand and contract. When the hydraulic cylinder 8 expands and contracts upward, it will drive the steel rod 9 and the sleeve 10, connecting cake 12, and connecting roller 13 fixed on the steel rod 9 to move upward synchronously. At this time, the upward movement of the sleeve 10 will drive the limiting roller 11 protruding from the middle of the sleeve 10 to slide along the L-shaped chute on the inner wall of the limiting sleeve 14 until the limiting roller 11 slides to be parallel to the ladle 1, realizing that the heat preservation cover 5 rises and then rotates and translates by 90 degrees under the indirect drive of the limiting roller 11 welded on the sleeve 10 of the steel rod 9, and the opening of the refining tank 2 is opened. While facilitating the pouring of materials, the inside of the refining tank 2 can also be quickly cooled down.

[0036] When the steel rod 9 moves upward, the steel rod 9 will also drive the connecting cake 12 welded in the middle to rise and rotate synchronously. When the connecting cake 12 rises, the connecting roller 13 fixed on the connecting cake 12 will pull the connecting rod 19 to slide along the surface of the first driving wheel 18 for one week, so that the connecting rod 19 pulls the first driving wheel 18 to rotate and tighten the tungsten alloy rope 24 on the side of the L-shaped rotating plate 17. At this time, the filter net 25 connected by the tungsten alloy rope 24 will slide up to half in the refining tank 2. After the connecting cake 12 rotates, the connecting cake 12 will pull the first driving wheel 18 and the L-shaped rotating plate 17 connected to the first driving wheel 18 to rotate synchronously with the rotation of the steel rod 9 with the support plate 16 as the center. At the top position of the steel rod 9, since the support plate 16 is connected to the external fixed position of the heating pipe 3 and rotates in place, and there is also a ladle 1 and a second driving wheel 21 defined on the heat preservation cover 5, when the heat preservation cover 5 rises, the tungsten alloy rope 24 will pull the filter net 25 to rise again in the refining tank 2 under the rise of the heat preservation cover 5.

[0037] At the same time of the second rise, since a rack bar 15 is fixed on the side of the hydraulic cylinder 8 and the rack bar 15 is fixed and immovable, and a driven gear 22 connected to the second driving wheel 21 is meshed with the teeth of the rack bar 15 at the top of the heat preservation cover 5, when the steel rod 9 drives the heat preservation cover 5 to rise and fall, the driven gear 22 will be meshed with the teeth of the rack bar 15 to rotate, and synchronously drive the second driving wheel 21 to rotate one week through the shaft of the support shaft block 20 to pull the tungsten alloy rope 24 to tighten three times. Finally, through the rise of the heat preservation cover 5 and the rotation of the first driving wheel 18 and the second driving wheel 21, the tungsten alloy rope 24 can drive the filter net 25 to slide up to the top of the refining tank 2 and hang in the air and translate to the side, so as to filter and remove slag from the molten steel in the ladle 1 through the filter net 25.
