Abstract

PURPOSE:To perform plate shape controlling by controlling the extent of deflection of work rolls by means of the roll deflection extent adjusting devices which receive the signal of an apparatus operating the rolling material shape on the outlet sid of the rolling mills by way of a roll deflection extent changing and setting device. CONSTITUTION:Roll deflection extent adjusting devices are provided to the outside circumferential surfaces on the deflection side of work rolls 1, 2 in contact with the work rolls 1, 2 in their longitudinal direction. The variable throttle valves 17 of the roll deflection extent adjusting devices are adjusted separately with a roll deflection changing and setting device 20 by the signal from an arithmetic device 27. This causes the fluid led to the pressing surfaces 7 by way of flow passage 13 to press the outside circumferential surfaces of the work rolls 1, 2 according to its amount. If the pressing force thereof is high, the gap of the work rolls 1, 2 narrows, resulting in the decreased thickness of a rolling material 6. If it is low, the gap of the work rolls 1, 2 widens, resulting in the increased thickness of the rolling material.
