METHOD FOR MANUFACTURING AUSTENITIC STAINLESS STEEL SHEET HAVING EXCELLENT SURFACE QUALITY

摘要

The present invention relates to a method for manufacturing a stainless steel sheet and, more particularly, to a method for manufacturing an austenitic stainless steel sheet having excellent surface quality using a double-roller thin plate casting apparatus. The method of manufacturing an austenitic stainless steel sheet having excellent surface quality using a double-roller thin plate casting apparatus including: a pair of casting rollers that rotate in directions opposite to each other; an edge dam that forms a molten pool by sealing up the sides of the rollers; and a meniscus shield that seals up the upper portion of the molten pool and supplies inert gas containing Ar, wherein a mixing percentage of Ar in the inert gas is 4 to 10%, and a mill scale thickness (μm) of the casting roller surface satisfies the following equation 1. [Equation 1] 0.6 X (mill scale thickness) < (Ar mixing percentage) - 1
