ABSTRACT:
A control device for the purpose of achieving highly precise rolled material. The response and robust stability of the rolled material tension and looper height are specified, and a controller is designed so that the rolling mill main motor and looper operate in concert to suppress variations in rolled material tension, thereby achieving stable optimum control which is responsive to the rolling state and rolling conditions.
