Abstract

Fluid cooled lance formed of composite refractory and metal for conveying oxygen-containing or other gases, with or without entrained solids, into or onto molten baths, including a heat and corrosion-resistant nozzle in the lance adapted to provide a localized increase in the gas delivered from the lance. The lance also includes a plurality of individual small diameter pipes facilitating increased resistance to operating stresses, providing an increased cooling surface, and allowing for the reduction of its external refractory envelope.
