Abstract
Iron and ferrous alloys are refined by a liquid oxidizing agent such as liquid air, liquid air enriched with oxygen, or liquid oxygen. The liquid may be fed on to the upper surface of the molten metal, and the refining may be carried out in combination with gaseous, solid or molten oxidizing agents.
