Abstract

PURPOSE:To obtain necessary sectional shape in the longitudinal direction easily, by finding the setting time of screw-down system necessary for movement of the screw-down position by the roll reduction correction amount, and controlling the rolling speed and said setting time in correlation so that said correction amount may correspond to the rolling direction position. CONSTITUTION:A computer for control 52 computes roll reduction correction amount DELTAS necessary for obtaining gauge variation DELTAh of specified sectional shape in the longitudinal direction, and determines roll speed VO relative to setting time (t) of motor-driven screw-down position control system 30 necessary for movement of the screw-down position according to correction amount DELTAS. Rolling speed V is determined from time (t) and the travel of the material being rolled. After outputting these values into a micro-controller 54, speed command VO is outputted into a roll speed control system 40 so as to control a motor 44 for driving the rolls. Then rolling is started; when rolling load F to be detected in load cell 46 reaches specified value and it is detected 48, that screw-down position measurement Sa is read, and control target value SO of the system 30 is varied in steps by the correction amount DELTAS. By this operation, a desired sectional shape in the longitudinal direction is given to the material being rolled 18.
