METHOD FOR STEEL REFINING Russian patent published in 1997 - IPC

Abstract RU 2095425 C1

FIELD: ferrous metallurgy, in particular, methods of refining the metal melts. SUBSTANCE: first, intermediate product is poured from steel melting unit into ladle in the amount of 5.0-15.0 mas.% of melt. This this case introduced before pouring of intermediate product into ladle is aluminum in the amount ensuring the content of aluminum in melt equalling 0.1-0.2%. Then introduced into ladle is desulfurizing mixture and melt is fully poured into ladle and after pouring the melt is blown through with inert gas. EFFECT: higher efficiency.
