Abstract

PURPOSE:The titled controller made to be possible to mutually independently correct the strip's tension value and the looper angle, by providing the compensation arithmetic unit for compensating the looper torque correction value for the strip and the rolling speed correction value. CONSTITUTION:The looper controller for the continuous rolling mill is constituted as follows. That is, the tension controlling mechanism is provided for adjusting the rolling speed correspondingly to the deviation of the tension value of the strip 1 between the adjoining rolling stands 2, 3, from the set point. Besides, the looper angle controller 9 is arranged for detecting the looper angle theta of the looper mechanism 4 provided between the stands 2, 3, and for adjusting the looper torque correspondingly to the deviation of above-described detected looper angle theta from its reference position. Further, in this looper controller, the compensation arithmetic unit 14 is provided for receiving the rolling speed alteration and the looper torque alteration from the arithmetic units 10, 12, and for adding the specified correction to these inputs, and for inputting the rolling speed alternation and the looper torque alternation to the speed controller 6 and the torque controller 8.
