METHOD FOR CONTROLLING SHAPE OF ROLLED STOCK

摘要

PURPOSE:To provide a method for controlling the shape of a rolled stock by which a proper manipulated variable is easily set. CONSTITUTION:In the method for controlling the shape of the rolled stock by which the shape such as sheet crown and flatness of a steel sheet 3 is controlled with a rolling mill 2 having a control operation terminal, manipulated variable is determined by a multiple regression model of given rolling conditions, the rolling of the steel sheet 3 is executed by giving this determined manipulated variable to the control operation terminal of the rolling mill 2 and the coefficients of the multiple regression model are successively corrected by successive least squares method based on the obtained actual data of rolling.
