FIELD: metallurgy, in particular, blowing molten metal with oxidizing gas. SUBSTANCE: oxidizing gas is supplied to molten metal found in reaction vessel through lances located below the surface of molten metal bath at lance inlet pressure of 85-170 bar. It is preferably to maintain the pressure within 90-120 bar. Oxidizing gas may be used in the form of oxygen with temperature of 5-50 C and density of 120-240 g/cu.dm. EFFECT: higher efficiency. 8 cl, 1 tbl
