Abstract

PURPOSE:To decrease the incidence of a length defect and to improve yield by providing a specific initial crown of a projecting shape to a roll so that a plate crown is formed with good accuracy in the same manner as with a roll having a roll bender function without providing said function to the roll. CONSTITUTION:The initial crown of the projecting shape expressed by the equation is provided to the roll in the stage of controlling the plate crown of the steel plate by the initial crown of the projecting shape provided to the roll. In the equation, C1' is the corrected initial crown, C1 is the initial crown, Cp is the actual plate crown, wi is the roll and rolling splitting width.
