Abstract

PURPOSE:To enable rolling of products excellent in shape coping with various kinds of elongation by using variable crown rolls as back up rolls and enabling them to move in axial direction. CONSTITUTION:When rolling a steel plate (a) by a quadruple rolling mill consisting of upper and lower work rolls 1, 1 and back up rolls 2, 3, variable crown rolls are used as back up rolls. At the same time, the rolls are installed to allow moving in axial direction. When partial elongation is caused in the rolled steel plate (a) to make the shape not uniform, back up rolls 2, 3 are moved in symmetric direction in accordance with kind of elongation of the steel plate (a). Or, one of back up rolls is shifted to opposite side of elongation of the steel plate (a) and the roll crown is adjusted to give desired curving tendency to optional position on the circumference of the work roll 1. Thus, rolling of the steel plate (a) is made in regular shape.
