THE METHOD FOR MANUFACTURING THE TI BEARING FERRITIC STAINLESS STEEL IMPROVED THE EQUIAXED STRUCTURE RATIO

摘要

PURPOSE: A method for improving the equiaxed structure ratio of Ti-bearing ferritic stainless steel is provided to achieve Ti-bearing ferritic stainless steel with superior surface quality by preventing ridging and roping. CONSTITUTION: A method for improving the equiaxed structure ratio of Ti-bearing ferritic stainless steel is characterized in that, during a refining process in a method for preparing Ti-bearing ferritic stainless steel, the content of Al and Mg in molten metal is increased to raise %(Al2O3)+%(MgO) of slag oxide.
