Abstract

PURPOSE:To provide the subject method comprising the steps of : using a looper in hot rolling of a steel plate as a loop storage mechanism at the tiem of passing and gripping the steel plate, and controlling the tension of the steel plate by a tensiometer disposed at the leading end of the looper at the constant speed of the roller or at the time of completion of passing the steel plate, thereby controlling the tension of the seel plate at asmall detection time constant.
