ABSTRACT:
Voltage, current, speed, and acceleration of each stand driving motor are detected and the rolling force of each stand is also detected. A processor unit is provided to determine the torque and the rolling force of the stands under no tension condition as well as under interstand tension condition for determining the interstand tension, and to determine a speed correction signal which is applied to a speed setter of the mill driving motor.
