摘要： In a pair cross rolling mill, a true rolling load free from influences of a thrust load occurring during rolling and an actual difference in load between roll ends are calculated, and sheet thickness control and wedge control are carried out through learning on the basis of detection values and calculated values. To accomplish a predetermined sheet crown, an actual sheet crown is estimated and calculated on a real time basis and is used for feedback control so that an actual roll bending quantity of a previous pass is reflected on a cross angle set value of next and subsequent passes at the time of completion of a given pass, and the cross angle set value is updated through learning. Further, the range of a mechanical crown for satisfying the roll shape in each pass and setup capacity is calculated, and a pass schedule is decided so as to attain the smallest number of passes.
