METHOD FOR FINELY DISPERSING OXIDE IN MOLTEN STEEL

摘要

PROBLEM TO BE SOLVED: To provide a method for dispersing a large quantity of fine oxides in molten steel. SOLUTION: After adding deoxidizer into molten steel, different molten steel having higher dissolved oxygen concentration than the molten steel added with the deoxidizer, is added so that the supplying quantity of the dissolved oxygen becomes 1-10 g/ton of the molten steel.
