Abstract
A control device for a rolling mill apparatus including at least one rolling mill stand for rolling a metal plate includes: a detection signal acquisition part for receiving, from an edge crack sensor, a detection signal of an edge crack at an end portion of the metal plate in a plate width direction; and a rolling condition decision part for deciding a rolling condition for the rolling mill apparatus. The rolling condition decision part is configured to change, if the detection signal acquisition part receives the detection signal of the edge crack, the rolling condition for the rolling mill apparatus from a first rolling condition immediately before detection of the edge crack to a second rolling condition which is more capable of suppressing growth of the edge crack than the first rolling condition.
