Abstract

PURPOSE:To improve shape control functions by effective application of the displacement of press rolls to work rolls in multistages rolling mills having shape control functions by providing the projecting shape crown corresponding to split rolls to the press rolls. CONSTITUTION:In the stage of rolling, a lower work roll 5 is offset in a rolling direction and pressure oil is supplied to cylinders 9-1-9-7 to project piston rods 8-1-8-7 individually by arbitrary extents and to move supporting plates 10-1- 10-7 by arbitrary extents, thereby pressing split rolls 14-1-14-6 to a press roll 15 and giving desired horizontal bending to the roll 15. Then, the roll 5 displaces in a horizontal direction and displaces in a vertical direction as well simultaneously, whereby the roll crown in changed and the shape of a rolled material S is controlled freely.
