METHOD FOR CORRECTING CAMBER OF THICK STEEL PLATE

摘要

PURPOSE:To correct flatness and camber at the same time and to improve the yield in rolling and the quality by correcting the camber generated in the stage of rolling by using a roll leveler. CONSTITUTION:A camber is measured with a camber gage and a steel plate is passed through a roll leveler while the passing position of the steel plate is deviated either to the right or left from a roll center Rc by as much as an offcenter DELTAS according to the camber. If the steel plate is cambered toward the right with respect to the passing direction, the steel plate is passed through the leveler while the center Pc thereof is deviated to the left side by the offcenter DELTAS from the center Rc according to the camber. If the steel plate is cambered toward the left with respect to the passing direction, the steel plate is passed through the leveler while the center Pc is deviated to the right by the offcenter DELTAS from the center Rc according to the camber.
