Description

Technical Field

[0001] This utility model belongs to the field of copper billet continuous casting machines, and particularly relates to a decarburization device for steel strip in copper billet continuous casting machines. Background Technology

[0002] In the SCR7000 continuous casting and rolling production system, the steel strip of the casting machine is coated with a uniform mixture of acetylene and oxygen to achieve heat insulation and protection. Therefore, the quality of the carbon coating directly affects the service life of the steel strip and the quality of the cast billet, thus determining the overall performance and quality grade of the final copper rod product. However, during continuous production, high-pressure water rinsing of the casting machine alone is insufficient to completely remove residual carbon scale from the steel strip, leading to uneven secondary carbon coating and deteriorating both the heat insulation effect of the steel strip and the forming effect of the cast billet. Currently, decarbonization is usually done manually by casting machine operators using hand-held wire brushes to remove residual carbon scale, which is labor-intensive, has poor homogenization effect, and poses certain safety hazards. Therefore, researching and designing an online steel strip decarbonization device with high process efficiency, operational stability, and dynamic adaptability has become an important part of improving the overall efficiency of the production line.

Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0012] like Figures 1-8 As shown. A decarburization device for steel strip in a copper billet continuous casting machine includes a base 1, a horizontal adjusting frame 2, a vertical adjusting frame 3, a clamping frame 4, and a grinding machine 5. The horizontal adjusting frame 2 is located on the upper part of the base 1 and is connected to the base 1 through a horizontal adjusting structure. The vertical adjusting frame 3 is located on one side of the horizontal adjusting frame 2 and is connected to the horizontal adjusting frame 2 through a vertical adjusting structure. The clamping frame 4 is connected to the side of the vertical adjusting frame 3, and the grinding machine 5 is fixed on the clamping frame 4. The horizontal adjusting structure includes a horizontal slot 8 opened in the upper part of the base 1, and two first mounting holes 6 provided in the lower part of the horizontal adjusting frame 2. A first bolt 7 passes through the first mounting hole 6, penetrates the horizontal slot 8, and a first nut 9 is threaded onto the first bolt 7. The vertical adjustment structure includes a vertical slot 12 in the middle of the horizontal adjustment frame 2, and two second mounting holes 10 in the middle of the vertical adjustment frame 3. A second bolt 11 passes through the second mounting holes 10, through the vertical slot 12, and is threaded with a second nut 13. A support 14 is connected to the side of the vertical adjustment frame 3, and the clamping frame 4 is fixedly connected to the support 14.

[0013] Working principle: Traditional casting machines often rely on high-pressure water washing to thoroughly remove residual carbon deposits from steel strips, requiring manual polishing. However, manual polishing suffers from inconsistent polishing results, is labor-intensive, and time-consuming. While manual polishing is flexible, allowing the wire brush to contact the steel strip, it is necessary to replace manual polishing with a device that can replace manual polishing. This device allows the polishing brush on the head of the polishing machine 5 to contact the steel strip surface and press it firmly against the strip. When the carbon deposits on the steel strip are thin, the contact area between the polishing brush and the steel strip needs to be small, and the pressure applied should be gentle to avoid over-polishing and damaging the steel strip (traditional steel strips become uneven after a period of use). When the carbon deposits on the steel strip are thick, the contact area between the polishing brush and the steel strip needs to be large, and the pressure applied should be firm to ensure a good polishing effect. The polishing brush uses a disc-shaped wire brush head and is mounted on the head of either the pneumatic or electric polishing machine 5. In use, the base 1 is fixed to the frame at the tension wheel of the copper billet continuous casting machine or to the housing of the drive motor of the tension wheel. The height of the base 1 is at an angle to the vertical direction. The horizontal adjustment frame 2 can be adjusted along the horizontal groove 8. During adjustment, loosen the first nut 9, move the position of the horizontal adjustment frame 2, and then tighten the first nut 9 to adjust the contact area between the grinding brush and the steel strip. The vertical adjustment frame 3 can be adjusted along the vertical groove 12. During adjustment, loosen the second nut 13, move the position of the vertical adjustment frame 3, and then tighten the second nut 13 to adjust the pressure of the grinding brush on the steel strip. Since the grinding machine 5 is an existing grinding machine 5, it is necessary to first fix the grinding machine 5 on the clamping frame 4. The top of the clamping frame 4 has a sleeve 18, and the body of the grinding machine 5 is located inside the sleeve 18. Two set screws are threaded on the sleeve 18, and then the grinding machine 5 is fixed with the two set screws. Then the clamping frame 4 is fixed to the vertical adjustment frame 3. For traditional copper billet continuous casting machines, you can refer to a continuous casting machine for copper billet continuous casting with publication number CN113798453A.

[0014] Example 2: Based on Example 1, the vertical adjustment frame 3 is connected to the side of the support 14, and the clamping frame 4 is rotatably connected to the support 14 via a pin 15. A tension spring 16 is connected between the clamping frame 4 and the vertical adjustment frame 3, and a limiting structure 17 is provided between the clamping frame 4 and the support 14. In this example, after the clamping frame 4 and the support 14 are rotatably connected via the pin 15, a tension spring 16 is connected between the clamping frame 4 and the vertical adjustment frame 3, so that the tension spring 16, the clamping frame 4, and the vertical adjustment frame 3 form a triangular structure. By using the tension spring 16 in conjunction with vertical adjustment, the contact and clamping degree between the grinding brush and the steel strip can be better adjusted. Because the tension of the tension spring 16 changes with the elongation length, the vertical adjustment frame 3 can be finely adjusted to keep the clamping degree within a suitable range. Compared with Example 1, this reduces the distance and number of adjustments required by the vertical adjustment frame 3. The limiting structure 17 is the limit position of the clamping frame 4 when it rotates downward without the steel strip restriction. It is a protective measure. The limiting structure 17 is a stop bar set on the vertical adjustment frame 3. The stop bar is located below the clamping frame 4.

[0015] The above are merely preferred embodiments of this utility model.
