Abstract
A method of oxygen refining molten hot metal to steel by blowing an oxygen stream at a predetermined flow rate from an oxygen supply source having a pressure from about 12 to about 18 atmospheres through the molten hot metal from a tuyere located beneath the surface of the molten hot metal and having a tuyere inlet and by varying the rate of flow of a finely divided lime injected into the oxygen stream is disclosed.
