摘要： PROBLEM TO BE SOLVED: To execute straightening for flatening a thick steel plate with a roll straightener so that defect in shape such as a camber due to the internal stress of the steel plate by straightening for flatening is not generated hereafter after cutting the plate. SOLUTION: After the thick steel plate is flatened at least apparently by straightening by passing the plate through the roll straightener, the max. deformation of the straightening rolls in the width direction of the steel plate of the straightening rolls of the roll straightener at the time of straightening for flatening and the reference deformation of the straightening rolls which is preset to prevent the generation of the defect in shape due to the internal stress of the steel plate by straightening for flatening the flatened thick steel plate after cutting the plate are compared. As a result of comparison, when the max. deformation of the straightening roll is over the reference deformation of the straightening roll, the flatened thick steel plate is again passed through the roll straightener on the straightening conditions that the max. deformation of the straightening roll becomes not larger than the reference deformation of the straightening roll.
