Abstract
PURPOSE: To roll the whole strip uniformly and with high precision, retaining smooth stability of permeability of the plate, by making the condition that the looper device does not kick up the strip, and simultaneously feeding back the strip operation which is derived by the looper device to the roll speed compensation device.
CONSTITUTION: The control of the device 9 is changed from tension constant control to looper 4 height constant retaining control by giving a command to the oil pressure device 9 and the speed compensation device 11 from the timing command device 12. At the same time, the control of the speed compensation device 11 is changed from the lopper 4 height constant control to tension constant control by the speed. The deviation of operation tension and setting tension which has been derived by the device 9 is taken into the speed compensation device 11, the rolling speed is controlled by giving a command corresponding to this deviation to the main motor 10, and tension of the strip 100 is kept constant. Thus, the tension which works to the strip 100 between the stands 2, 3 can be controlled so that it can be constant until the tail passes through the stand 2.
