Abstract
PURPOSE: To compensate velocity lowering at biting time of a material to be rolled by simple constituent, by means of determinating velocity returning time from the response volocity of a control system as a reason, and of being subjecting to determine a max. value of velocity lowering quantity by current variation rate at the load biting time.
