ABSTRACT:
An improved method of refining molten steel is disclosed. Inert gas such as argon is injected into the molten steel in a refining vessel through tuyeres at the bottom and blown through a lance from the top of the vessel. The method is particularly useful for producing steel of very low oxygen content.
