Abstract (en)
A control device for a rolling apparatus is a control device for controlling a rolling apparatus including a pair of mill rolls for rolling a metal strip, an unwinder for unwinding the strip toward the pair of mill rolls, and a winder for winding the strip rolled by the pair of mill rolls, including a rotation control unit for controlling rotation of the mill rolls, a velocity acquisition unit configured to acquire velocity of the strip between the unwinder and the mill rolls, and a separation detection unit configured to detect separation of a tail end of the strip from the unwinder. The rotation control unit is configured to stop the rotation of the pair of mill rolls, based on a separation timing which is a timing when the separation of the tail end from the unwinder is detected by the separation detection unit and the velocity of the strip acquired by the velocity acquisition unit.
