ABSTRACT:
A process for the in-ladle treatment of liquid steels by injecting gas through the ladle bottom. The process comprises injecting at least one inert gas from locations which are distributed over the ladle bottom in such a way as to form at the surface of the liquid steel an annular swelling, the outside edge of which is close to the inside edge of the lining of the wall of the ladle. An oxidizing gas may be mixed with the inert gas for decarburization. The process is applied in particular to the treatment of carbon steels.
