Abstract

PURPOSE:To freely control the sheet crown, by bearing the rolling load with the drum of a work roll through a hydraulic pressure, and by varying the distribution of the hydraulic pressure along the longitude of the work roll. CONSTITUTION:The rolling load of a work roll 1 is born by a support beam 5 through a hydraulic pressure in a rolling mill. The said hydraulic pressure is divided into three chambers 7, for example. The length of each chamber 7 in the direction of roll axis is set to (b), (a), (b), and its length in the direction of roll diameter is set to (c). The pressure distributions P1, P2, P1 in the direction of roll axis of the pressure given by the support beam 5 are given by P1=CP01.P2=CP02 in which P01, P02, P01 are the hydraulic pressure of each chamber 7. If the total pressure is designated by P, the relations P=Q+F=2bP1+aP2, Q=Wq are established. In the formula Q is a total pressure given by a rolled material 2, F is a bending force, and (q) is the rolling pressure. Then, by varying P01, P02, the pressure distribution given by the support beam 5 is controlled.
