Abstract

A device for carrying out metallurgical processes, especially for refining or pre-refining pig iron, for refining and alloying steel and the like, by blowing on the starting materials charged in a container provided with a refractory lining, with a blowing agent oxygenated, especially pure oxygen, and at the same time adding solid, fine-grained additions, such as CaO, characterized in that in a water-cooled lance, a down-pipe connected to the outside atmosphere is centrally mounted, intended for the supply of additions, the lower mouth of the down tube being found in the region of the expansion zone of the blowing agent, so that the additions supplied without pressure are absorbed inside the jet.
