<p>PURPOSE:To obtain the best width shape in a widthwise rolling method which rolls a rolled material at the target total rolling reduction by plural times of reversible widthwise rolling by making the width undersizes of that arises at the preceding end of the rolled material by the rolling of the respective preceding passes and the widthwise rolling reduction of the respective next passes after the respective preceding passes to coincide. CONSTITUTION:A titled method is a widthwise rolling method which rolls a rolled material at the target total widthwise rolling reduction by plural times of reversible widthwise rolling. The respective widthwise rolling reductions of the entire pass are so set that the undersizes of the width that arise at the preceding end of the rolled material by rolling of the respective predecing passes and the widthwise rolling reduction of the respective next passes after the respective preceding passes coincide. Thus, the optimization of the setting of the widthwise rolling reductions in the widthwise rolling and the minimization of the undersizes of the width that arises that arise at the end part of the rolled material are made possible and the best width shape is obtained.</p> |
