Abstract

PURPOSE: To simply, surely control the shape of a rolled sheet material, by applying a bending moment to a large diameter work roll in order to change the condition of its deflection, in a rolling mill equipped with work rolls of different diameters in which a small diameter work roll is included in a multistage cluster mill type upper roll group.
CONSTITUTION: The said rolling mill is provided with a small diameter and a large diameter work rolls 1, 4, an intermediate roll 2, backup rolls 4, 5, hydraulic cylinders 6, 6', roll gap adjusting devices 7, 8, and roll housings 9, 9'. When a sheet material S is rolled by this rolling mill, the crown of the sheet material S rolled by the upper cluster mill type roll group supported by plural backup rolls 3, is smaller than the lower side crown of the sheet material S rolled by the lower two-high rolls 4, 5. A bending force is applied by the hydraulic cylinders 6, 6' to the lower work roll 4, the rolling load distribution between the lower work roll 4 and the sheet material S is changed so that the shape is improved as shown by the full line.
