METHOD OF DEDUSTING ABOVE ZONE OF REFINING IN CONVERTER Russian patent published in 2009 - IPC C21C5/38

Abstract RU 2369641 C2

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 i^b _s≥i^c _s≥i^e _g, where i^b _s≥i^c _s≥i^e _g are pulses of forces of jet flows of oxygen blow system, of cone shaped gas system and exhaust dusted gases, kg·m/cm².

EFFECT: enhanced efficiency of dedusting above zone of refining in converter cavity.
