ABSTRACT:
A blowing apparatus for simultaneously delivering gaseous and solid materials to a hot metal melt during refining is presented. The blowing apparatus or blowing lance provides a novel structure of an inner block, an outer block housing, and tubing wherein incompatible materials (i.e., oxygen and carbon) may be safely and simultaneously delivered by use of a protective structure which also functions as a cooling device. The blowing lance further includes a variety of nozzles for blowing materials both above and below the surface of the metal pool.
