Short scratch lines have been found on the surface of steel sheets during commissioning. By adjusting the control parameters of the line and investigating the manufacturing process of inlet deflector rollers, the root cause of the scratches was found. By modifying the manufacturing process of the rollers, the scratches have been thoroughly eliminated, and quality steel sheets have been consistently produced in the recoiling line.展开更多
