Abstract
PURPOSE:To restrain generation of surface flaws on side edge parts by restricting the total draft of horizontal rolling by edger mill to be <=50% and specifying an edging amount per pass. CONSTITUTION:Generation of surface flaws and folds on side edge parts is restrainable by restricting the total draft of horizontal rolling to be <=50% and an edging amount per pass W by an edger mill to be 40-150% of a sheet width difference B in the thickness direction of a stock to be rolled after rolling for edging passes of a stainless steel sheet by an edger mill. If the total draft exceeds 50%, folds on side edge parts are not flattened in edging passes by the mill; if the edging amount W is <40% of the B, folds are not completely flattened, and if the total draft is >150%, a dog bone is formed and deep wrinkles are formed on a slope.
