VERFAHREN ZUM EINSCHMELZEN VON EISENSCHWAMM

摘要

A method for melting sponge iron is provided in which pieces or pellets of sponge iron, which may be partly replaced by scrap, are placed on the surface of a molten metal bath. Oxygen is added to the metal bath at a position below the surface of the bath. Further substances required for the melting process are added to the metal bath under pressure at a position below the surface of the bath. The further substances that are added include solid carbonaceous dust and fine-grained sponge iron.
