Abstract

PURPOSE: To improve the response capability of the control system against disturbances and to improve the strip thickness and width accuracy of a stock to be rolled by optimally controlling with consideration for interference between a tension between stands, looper angle, and a strip thickness.
CONSTITUTION: At the time of biting a strip 10 as a stock to be rolled by an (i+1)th stand 14, a looper 16 rises and starts a control after the looper 16 is brought into contact with the strip 10. A control computer 30 stores values of respective variables at the control starting moment (rolling load, drafting position, drafting speed, mill speed, tension between stands, looper torque, looper angular velocity, and looper angle) and calculates deviations of respective state amounts from the control starting moment. Correction amount U for respective operation values is calculated based on the above calculated deviation values and outputs the correction value U to respective controllers to concurrently correct all of an outlet side strip thickness, a tension between stands, and a looper angle.
