CONTINUOUS CASTING METHOD FOR FERRITIC STAINLESS STEEL

摘要

A continuous casting method of ferritic stainless steel is provided to improve a quiaxed grain ratio of a cast steel slab by controlling the content of N and Ti in a steelmaking process according to casting temperature of the ferritic stainless steel. Ferritic stainless steel contains 0.020 or less of copper, 0.020 or less of nickel, 0.3 or less of silicon, 2.0 or less of molybdenum, 17.0~19.0d of chromium and inevitable impurities. TiN crystallization temperature controls a component for ferritic stainless steel to improve a quiaxed grain ratio of a cast steel slab.
