FIELD: metallurgy. ^ SUBSTANCE: method consists in refining metal with jets of oxygen blow. A multi-jet cone shaped gas burner is installed above system of oxygen blow; jets of gas of this system are directed counter flow of exhaust dusted gases providing a counter pressure to his flow at maintaining the condition ibÇèsëÑicÇèsëÑieÇèg, where ibÇèsëÑicÇèsëÑieÇèg are pulses of forces of jet flows of oxygen blow system, of cone shaped gas system and exhaust dusted gases, kgm/cm2. ^ EFFECT: enhanced efficiency of dedusting above zone of refining in converter cavity. ^ 3 cl, 2 dwg, 2 tbl |
