Abstract

PURPOSE:To remove the fluctuation of interstand tension, by effectively combining the detecting signals obtained from the tensiometer and tension controller, at controlling the interstand tension of the multistand tandem mill. CONSTITUTION:When the material 1 to be rolled is rolled by the multistand tandem mill providing the reductin rolls 2 ... into the rolled material 10, the quantity of detection by each of the operating condition dentector 3 (detecting voltage, current, R.P.M., rolling load, roll gap, etc., of the roll driving motor) and the rolling condition detector 4 (thickness gauge, tensiometer, width gauge, etc.) are inputted to the arithmetic output unit 5. The unit 5 operates the quantity of correction for the speed of each stand, and delivers this quantity of correction as the input to the turning speed control for the driving motor at each stand.
