Abstract

PURPOSE: To allow the stability of the strip thickness controlling and to prevent the deflection of the shape of the material to be rolled after rolling by correcting the position of rolling reduction of rolling stand with the thickness meters and the temperature meters which are set on plural rolling stands.
CONSTITUTION: The sheet thickness meters 2 and the temperature meters 3 are set between, at least, over two stands, the sheet thickness and the surface temperature of the material to be rolled 1 are detected at the passing time of the tip end of the material to be rolled 1, and the rolling temperature of the material to be rolled 1 bitten in the next stand roll is predicted with this detected temperature. The limitation of the correcting amount of the position of rolling reduction is continuously executed if the deflection of the shape of material to be rolled 1 is predicted on the case of correcting the position of rolling reduction of the next stand based on the deviation of the predicted value of this rolling temperature of the material to be rolled 1 and the preset target value, and the deviation of the detected value of the sheet thickness and the preset target value. That is, the correction of the position of rolling reduction to be corrected can be effectively distributed to the rolling stands of, at least, over two stands, so the stability of the sheet thickness control is improved.
