三。刮板辊划伤，缺陷位于钢板前后。问题的主要原因是辊子表面有异物或压榨辊轴承卡住。具体解决方法：清除滚筒表面的异物，调整压榨滚筒或轴承。
4s辊划伤，缺陷位于钢板前后。产生问题的主要原因是辊子表面有异物，炉体与出口活套的张力差过大，导致s辊打滑。具体解决方案：清除辊子表面的异物，调整出料环与炉膛之间的张力控制。

Scratch caused by production process

 1. There are foreign matters on the surface of the guide plate at the inlet and outlet, and the defect is located on the back of the steel plate. The main reason for the problem is that there are foreign matters on the surface of the guide plate. Specific solutions: regularly check the wear of the guide plate, repair and adjust; reinforce the loose guide plate screws in time, and remove the foreign matters on the guide plate surface in time.

 2. The spray pipe is scratched, and the defect is located on the back of the steel plate. The main reason for the problem is that the tension is too small and the lower surface of the strip steel is in contact with the nozzle. Specific solution: appropriately increase the tension of strip steel in cleaning section. 

3. The squeegee roll is scratched, and the defect is located on the front and back of the steel plate. The main cause of the problem is that there are foreign matters on the surface of the roller or the bearing of the squeezing roller is jammed. Specific solution: remove the foreign matter on the surface of the roller and adjust the squeezing roller or bearing. 

4. The s roll is scratched, and the defect is located at the front and back of the steel plate. The main cause of the problem is that there are foreign matters on the surface of the roller, and the tension difference between the furnace body and the outlet looper is too large, resulting in s-roll slipping. Specific solution: remove the foreign matters on the surface of the roller and adjust the tension control between the outlet loop and the furnace.
