Abstract

A process of treating molten steel to remove insoluble nonmetallic inclusions to produce clean and ultra clean steel comprising the steps of pouring molten steel into an insulated tundish having an insulated cover, maintaining a neutral atmosphere in said covered insulated tundish, stirring the molten steel with inert gas within said covered insulated tundish so as to precipitate said insoluble nonmetallic inclusions and move the same to the surface of the molten steel, maintaining and increasing molten steel temperature in said covered insulated tundish, directing the insoluble nonmetallic inclusions from the tundish, pouring clean and ultra clean steel from the covered insulated tundish.
