Abstract

PURPOSE: To control interstand tension, by installing an arithmetic controlling device for operating the inputted data such as the forward tension, the feed-in side sheet thickness, the rolling load, the roll gap and the various elements of the motor, of the stand in the first stage in order to adjust the speed reference and the correction value for the speed, and for keeping the forward tension at a specified value.
CONSTITUTION: The fourth operator operates the forward tension of the first stand by using a rolling load and a rolling torque operated by the first operator and a torque arm operated by the third operator. The fith operator operates the correction value for the rolling speed necessary to make above operated forward tension of the first stand match to the desired value. Accordingly, the torque arm is properly corrected correspondingly to the change of the rolling condition, the forward tensin is accurately detected, and the rolling speed of the stand is suitably corrected; as a result, the forward tension of the stand is controlled to the specified value.
