Abstract
Procedure for refining phosphorus-poor pig iron in a converter in which one or more nozzles, consisting of an inner tube and a tube surrounding the inner tube, are arranged in the refractory masonry below the bath surface. where through the inner tube oxygen is injected and through the outer tube a liquid or gaseous protective medium is injected, so that the protective medium surrounds the jet of oxygen, characterized by the fact that together with oxygen fine lime is incorporated into the melt .
