Abstract
PURPOSE: To restrict the tension fluctuation owing to the fluctuation of the coil feed rate or the concentration, by suitably correcting the compensating gain for the deviation of the tension value computed by a tension computer from the aimed tension value.
CONSTITUTION: A tension computer 4 detects an interstand tension Ti from the electric current, voltage and rotational speed of a motor 6 driving a rolling roll of each stand, the rolling load and the roll gap; a speed compensating controller 5 applies a compensation process in at least one or more of proportional, integral and differential modes to the deviation of the tension Ti from the aimed tension value Toi. On the other hand, a valve 10 is opened to start the oil feed a prescribed time after the material 3 is bitten by each stand, and the valve 10 is closed a prescribed time before the tail end of the material 3 drops out of the stand. The oil feed rate is controlled by a flow rate controller 12, and an oil feed rate controller 11 decides the flow rate to be commanded. A gain corrector 13 corrects the said speed compensating gain correspondingly to the deviation from the set oil feed rate decided by the controller 11; the speed compensating controller 5 uses the corrected control gain for controlling the motor 6 through a speed controller 7.
