摘要

PURPOSE:To perform a highly accurate tension-controlling, by controlling a tension produced between stands by means of rolling torque and rolling load when the cross-sectional area of a material is larger than the prescribed cross-sectional area, and controlling the tension by a looper device when said area is smaller than the prescribed one. CONSTITUTION:In rolling a material having the cross-sectional area larger than the prescribed one, rolling load of each stand 1, 2,- (i),-(n) is measured by providing a load meter 5 each, and rolling torque is measured by a torque-meter or a main motor 6. The speed of each main motor 6 located at the opposite side of a pivot is operated so as to make each tension produced between the stands coincide with the desired tension by estimating a tension between the stands from said measured value. When the cross-sectional area of the material is small, a small inertial looper-device 4 is provided to perform a PID control against looper angle theta so as to obtain the desired tension without being affected by the inertial force by considering the looper angle theta, thereby operating the speed of the motor 6 located at the opposite side of the pivot.
