<p>PURPOSE:To obtain the best width shape of a rolled material in a method for widthwise rolling which rolls the material at the target total width rolling reduction by twice of widthwise rolling in one direction. CONSTITUTION:A titled method is a widthwise rolling method which rolls a rolled material at the target total widthwise rolling reduction by twice of widthwise rolling in one direction. The respective widthwise rolling reductions are so set that the undersizes of width that arise at the preceding end of the rolled material in the 1st pass of rolling and the widthwise rolling reduction in the 2nd pass coincide. Thus, the setting of the rolling reduction in the widthwise rolling is optimized, and the undersizes of width are minimized. Therefore, the best width shape is obtained.</p> |
