Abstract
The correction ratio of the widthwise end parts of a plate (P) is calculated from the degree of offset from the center of a pass line in the plate width center and from the load on pressing cylinders (4a 4b) at the two widthwise ends. The degree of tightening of the pressing cylinders (4a 4b) at the two widthwise ends is individually controlled and vertical deflection is corrected. The degree of tightening of a plurality of hydraulic crowning cylinders (12) is individually controlled and lateral deflection is corrected on the basis of detection values from a plurality of deflection detection sensors (21). The plate width center is determined from the degree of offset of the plate (P). The degree of compressive deformation in the plate thickness center is calculated on the basis of the mill constant of compressive deformation and the load at the plate width center. The degree of tightening of the plurality of hydraulic crowning cylinders (12) is individually controlled and the compressive deformation is corrected by multiplying the degree of compressive deformation in the plate thickness center by a function of the degree of offset and the plate width in the position of each of the hydraulic crowning cylinders (12).
