Abstract
In a rolling mill having a pair of upper and lower work rolls, defining a pressure gap therebetween through which a material is passed to be rolled, a method and apparatus for controlling the rolling mill under the different peripheral-speed rolling operation in which one of the rolls is driven at a predetermined peripheral speed by controlling the speed of a motor for driving the one roll, and the other roll is controlled to generate a torque corresponding to a difference, between a total torque required for the rolling operation and a torque generated by the one roll by controlling the torque of the motor for driving the other roll on the basis of a torque command corresponding to the torque difference.
