Abstract

PURPOSE: To perform highly accurate shape controll of a rolling material by judging magnitude of horizontal component of force of an offset roll and giving horizontal reaction force of magnitude and direction corresponding to the horizontal component of force to the offset roll.
CONSTITUTION: Rolling force is applied by upper and lower bracing rolls 1, 2, and a signal of rolling force detected by a load meter 14 and signals of horizontal component of force of each cylinder 9 detected by an adder 15 are operated by a controller 16. Direction of receiving horizontal component of force of an upper work roll 3 is judged by the controller 16, and setting of pressing direction of a cylinder 11 or 11' is made. At the same time, magnitude of horizontal reaction force is set. Further, the control signal is transmitted from the controller 16 to a changeover valve 13. The changeover valve is changed to required position in accordance with decision of positive or negative of horizontal reaction force, and pressure oil from a oil pressure supply source 12 is supplied to the cylinder 11 or 11'. Accordingly, horizontal reaction force of magnitude corresponding to rolling force and horizontal force can be given to the axle box 10 of the upper work roll 3.
