Abstract

PURPOSE: To make easier the control of plate shape by bending intermediate roll in the direction parallel with the flow of plate and by intersecting the axial line of the intermediate roll with the axial rotation of work roll to obtain desired roll crown of work roll.
CONSTITUTION: The intermediate roll chock 2 is moved in the direction parallel with the flow of plate by rotating the worm 7, the worm sheel 8, and the screw shaft 12 by means of a driving device. For example, without the intermediate roll 2 on the right side being moved, the movement of the outside ones of the intermediate roll 2 on the left side is made greater, whereas that of the inside ones is made smaller to change the axial line of the intermediate roll 1 and then to change the roll crown of work roll. Thus, optional roll crown can be obtained and thus better rolled products can be obtained
