METHOD FOR PRODUCING METALLIC IRON

摘要

When a mixture containing an iron oxide source and carbonaceous reducing agents is heated and reduced to manufacture metallic iron, carburizing and melting of solid metallic iron produced by heating and reducing are progress ed efficiently so that metallic iron particles can be manufactured efficiently under high thermal energy efficiency. A method for heating, reducing and melting a raw material mixture containing carbonaceous reducing agents and aniron oxide-contained substance to manufacture metallic iron, characterized in that a liquid fraction in a solid and liquid coexisting phase of produced slag containing a multi-component gangue is controlled to thereby accelerate melting of solid metallic iron produced.
