ABSTRACT:
A method for producing 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 gas onto or beneath the surface of the bath while introducing an inert gas to the bath from beneath the surface thereof during said top blowing. The rate of inert gas is increased progressively during top blowing of oxygen and the rate of oxygen is decreased progressively during said top blowing.
