Abstract

PURPOSE:To improve the yeidls of rolled materials, by controlling the crown and partial shapes of rolling materials by changing the variable crowns of the work roll, the stay roll, or the intermediate roll. CONSTITUTION:When, for example, rolling is performed after the internal pressure in hollow chambers 6 at both ends of a lower stay roll 5 is adjusted to P1 by enclosing a pressure liquid, the press-contacting surfaces of the hollow chambers 6 are depressed by rolling force received from a work roll 3, and the free surface is swollen. In this case, the contacting surfaces of the hollow chambers 6 with the roll 3 are swollen by a horizontal load P2 applied to the free surface of the roll 5 with a pressure roll 7 having a width which is narrower than that of the hollow chambers 6 and which can be moved along the direction of length. The load P2 can be adjusted to appropriate ones by means of a pressure adjusting hydraulic cylinder 9 and any desired shapes of the profile of the roll 5 can be obtained, and thus, the yield of rolling materials can be improved.
