Abstract

PURPOSE:To perform shape controlling by providing work rolls with deviation in a rolling line direction with respect to backup rolls, and adjusting the deflection with the screw down of the work rolls by means of auxiliary rolls which are displaceable in the rolling line direction. CONSTITUTION:Upper, lower work rolls 1, 2 are provided with deviation of a fixed space S in a rolling line direction with respect to the axial centers of upper, lower backup rolls 4, 5, If, in this state, screw-down rolling of a rolling material 6 is performed, the work rolls 1, 2 deflect so as to escape to the lower stream side. Thereupon, a cylinder device 17 is driven to displace auxiliary rolls 7, 8 in a width direction along support bases 12, 13 until they match the width size of the rolling material 6 or to move and adjust them until they meet the plate shape in the width direction, whereby the deflections of the work rolls 1, 2 are changed in that longitudinal direction position and the shape controlling of the rolling material 6 is thus accomplished.
