Abstract

PURPOSE:To improve the asymmetry of the slab shape, and to improve the product yield, by deciding the draft percentage of the following rolling pass in the direction perpendicular to the former pass depending on the thickness after the draft adjustable rolling pass. CONSTITUTION:At first, by the draft adjustable rolling for changing the roll gap during the rolling work, the plan shape of the rolled material after the rolling work is made approximate rectangular. The draft percentage of the following rolling pass perpendicular to the former rolling pass is specified to 3% or less of thickness obtained by the draft adjustable rolling pass. the relation between the draft percentage and the average bulging clearance after the rolling work shows a sudded change bordering on 3% of the draft percentage. If the draft percentage is not more than 3%, the bulging clearance can be considerably reduced. These condidtions are set for improving the lateral shape, however, they can be also be applied to the draft adjustable broadside rolling for improving the crop shape.
