Abstract

During the pouring of steel from a nozzle in the bottom of the ladle into ingot moulds, oxygen is injected into the stream of steel through a bore in the nozzle, perpendicularly and radially or tangentially to the stream. Particulate additives may be entrained in the gas stream. The apparatus for carrying out the method comprises a teeming nozzle 1 (Fig. 1), in the bottom of a ladle, having an enlarged cylindrical portion nearer the outlet, than the inlet, end thereof and a single bore for the injection of oxygen, through the nozzle, perpendicular and radial or tangential to the passageway therein extending into the enlarged cylindrical region, the oxygen being supplied from conduit 5.
