Abstract

PURPOSE:To prevent generation of flaws on longitudinal ends and to improve the production yield by specifying a roundness on the top and rear end corners and a roundness on edges after cutting a slab by a prescribed length. CONSTITUTION:Corners (j) and edges (k) are generated on a slab (a) after rolling. A roundness on the corners (j) and a roundness on the edges (k) are specified to be >=15mm and >=2mm, respectively. A tendency to generate rolling flaws caused by edges is reduced, so that cutoff lengths in the top and rear end parts are reduced by a shortened length brought by the reduced tendency.
