Abstract

PURPOSE: To control the gauge and breadth of plate simultaneously, by controlling the gauge and rolling in each stand before the final stand, and controlling the breadth at the final stand, detecting the breadth after broadside rolling, and feeding the detected value back as the screw-down speed command signal of the final stand.
CONSTITUTION: A switching circuit 2 is provided in a signal command route from a tension control device 16 to a screw-down speed adjusting device 17, and the conduction of tension control signal is controlled. A breadth derector 3 is provided at the exit side of the final stand, and the steel strip breadth after rolling at the final stand is detected. The detected value by the breadth detector 3 is inputted into a breadth control device 4. The standard value of breadth size is set in the device 4, and is compared with the inputted breadth detected value. A control signal corresponding to the deviation of this comparison is sent into the device 17. At the same time, a circuit closure signal is delivered from the device 4 to the switching circuit 2, so that the automatic gauge control signal inputted into the device 17 from the tension control device 16 may be cut off.
