<p>PURPOSE:To roll a material into a flat sheet throughout its whole body in its width direction by obtaining the deviation between the shape obtained by actual rolling and the shape estimated from a mathematical model and correcting the mathematical model of a rolling mill at the final stage. CONSTITUTION:A material to be rolled delivered from an unwinder 61 to be wound up by a winder 62, is rolled by the 1st stand or the 2nd stands 63-65. The shape of a manufactured product is detected by a shape detector 66, and is inputted to a shape control device 67. The device decides an optimum manipulated variable by using equations, estimates a crown of base material, performs set up calculations at the next pass, and outputs the set signal 68 of manipulated variable to each stand. Accordingly, the shape is comprehensively controlled to improve the accuracy of shape control, by taking into consideration the crown of base material.</p> |
