Abstract

Process for the continuous refinement of a pig iron stream, by injection of a gas with a high percentage of oxygen, characterized in that the pig iron stream that is to be tuned in a metal bath that is already present is introduced, at least partially refined and whose percentage of carbon is lower than the percentage of carbon of the pig iron to be refined, said pig iron stream is mixed in said bath, a refining gas containing oxygen is injected into said bath at a point of this bath in which the mixture has already been made and in which the percentage of carbon is reduced, and in which the oxygen can not come to directly come into contact with the pig iron stream and, finally, is continuously extracted from the bath a metal stream with a reduced percentage of carbon.
