Abstract

PURPOSE:To reduce the crown and edge drop of a product sheet without harming its flatness, by applying a chamfering work to a backup roll correspondingly to the rolling load of each stand generated according to its draft pattern. CONSTITUTION:In a tandem rolling work, a chamfering width CW and a chamfering cd are selected correspondingly to the rolling load of each stand generated according to its draft pattern. These chamfering width and depth are given to a backup roll, and the rolling work is performed. In case of a tandem mill equipped with a roll bender, the pressure of each bender is selected as a value optimized according to the chamfering amount and the rolling load. By the present method, the crown and edge drop of a product sheet are both reduced, and a shape control generating no center buckle, etc., can be performed.
