ABSTRACT:
A method for producing stainless steel in a top-blown molten metal vessel having a hot metal charge to form a bath. The method comprises top blowing from a lance oxygen and/or a mixture of oxygen and inert gas onto or beneath the surface of the bath while introducing a low flow rate inert gas to the bath from beneath the surface thereof during said top blowing. The ratio of oxygen-to-inert gas is decreased progressively during top blowing. The relative flow proportion of top-blown gases and bottom-blown gases remains substantially the same throughout the process.
