Abstract

PURPOSE:To refine low C low N stainless steel in a stable manner by controlling Cr of molten crude stainless steel to below the target value of the product;carrying out oxygen blowing under reduced paress. ;and setting upper limits to Si% of the moltensteel and that of a Cr alloy to be added.
