Abstract

PURPOSE:To perform shape controlling with good accuracy by determining the axial position of intermediate rolls for the rolling material of this time and the set value of work roll bending force through computation by the use of the actual records of the previous rolling material. CONSTITUTION:The shape of the rolling material of this time is calculated 17 and predicted from the predetermined relations, formula I (predicted sharpness of the side edges of the rolling material of this time), formula II (predicted sharpness of the central part) and formula III (shape index) by using the actual rolling records including the rolling mill outlet side shape detection values 6, 11, 12 of the previous rolling material, and the roll bending force measured value 7 and intermediate roll axial direction position set value in the previous rolling as well as the rolling conditions including the predicted values of the roll bending force and intermediate roll axial direction position for the rolling material of this time. And the roll bending force and intermediate roll axial direction position at which said predicted shape becomes best are obtained and these are made initial set values for rolling of this time.
