ABSTRACT:
Pig-iron is refined into steel by blowing oxygen and a protective screen of an encasing gas through injecting means located at or near the bottom of a converter containing a melt of molten metal. The encasing gas while protecting the injecting means, allows it to be consumed at substantially the same rate as the bottom of the converter so that the injecting means is not left projecting from the bottom of the converter. The encasing gas can be one which is inert to the melt or the metal of the injecting means or both, or it can be a gas which reacts sluggishly with the melt or the material of the oxygen feed pipe or both. Desirably, the oxygen jet is circular in cross-section and the encasing gas is in the form of a concentric jet.
