Abstract

PURPOSE:To control the thickness distribution in the transverse direction of a rolling sheet and to prevent the uneven wear thereof in a 2-stage rolling mill by providing a device for bending work rolls and a device for shifting the rolls. CONSTITUTION:A rolling sheet 10 is rolled to a desired thickness between the work rolls 1 and 2. Hydraulic pistons 7, 8, 9 of the work bending device are operated by which the rolls 1, 2 are adjusted and the thickness distribution in the transverse direction of the sheet 10 is controlled as desired. The rolls 1, 2 are shifted in the axial line direction to each other, by which the contact surfaces with the sheet 10 is shifted and the wear profile of the rolls 1, 2 is adjusted.
