Abstract
PURPOSE:To enable soft-landing of a looper roll on a rolled stock by installing a torque giving device and a speed detector in the looper device of a rolling mill and controlling a looper driving device by output of the detector. CONSTITUTION:A detector 8 that detects rotation speed of a looper roll 7 is provided in the lower part of a looper arm 6, and the number of rotations of the looper roll 7 that rotates in contact with a rolled stock is detected. At the same time, timing of speed reduction command is given correctly to a looper driving device by resistance torque of the looper roll 7 given by a torque giving device 9 that gives proper rotational load torque to the looper roll 7. Accordingly, ascension of the looper roll 7 is controlled quickly, and the looper roll can be soft-landed on the rolled stock without generating excessive tension in the rolled stock.
