Abstract

PURPOSE:To control a metallic strip into a good form by adjusting displacement installing a taper sliding liner between a fixed bearing and a solid frame and thereby controlling amount of bending deflection of separated backup rolls. CONSTITUTION:A pair of movable taper sliding liners 8 are provided between a fixed bearing 4 and a solid frame 5, and these are moved in opposite direction symmetrically to each other. In this case, when the taper sliding liner 8 is moved, the position of the separated backup roll 1 is changed. However, the extent of change has no relation with the amount of rolling load. Therefore, variation of plate thickness is compensated by AGC and does not give an adverse effect on the accuracy of plate thickness. By this way, form control of metallic strip becomes very easy. Further, strip rolling of various conditions can be treated with the same roll to improve recovery.
