Abstract

PURPOSE: To reduce the crown and the edge drop of the strip, by keeping the middle of the rolls of the rolling mill on the height of the pass line, and by adjusting the height of the roll chocks so as to keep either one of rolls on the driving side and the operating side higher than the pass line and to keep other one lower than the pass line.
CONSTITUTION: For example, the middle of rolls of the tandem mill is kept on the height of the pass line, and the height of the roll chock on the driving side is kept different from the height of the roll chock on the operating side; as a result, the roll 2 slightly inclines against the pass line. The steel sheet 1 is rolled while being twisted between the stands Fn and Fn-1 so that the tension in the direction of breadth of the strip is uniformly distributed while undergoing the rolling work.
