Abstract：To the steel coil problems of tower and the overflow edge in roll process of the cold rolled mill, the shape irregular cause of cold rolled strip coil were analyzed in this paper. Some measures were taken, such as the CPC outline dimension of the cylinder was transformed, the unwinding machine lining board was measured and the lining plate after serious wear were replaced, the deviation value of uncoiler base and the mill center line was adjusted, deviation value of intermediate roll shifting was eliminated, the accuracy of work roll size and the cooling effect steel coil were improved, the roll preheat time was adjusted and so on. The quality of coil shape was improved. The rectification ratio of the steel coil was reduced from 21.7% to 6% per month, and the telescoping and overflow edge defects were effectively controlled.
