METHOD FOR PREVENTING OUTBURSTS DURING CONVERTER BLOW Russian patent published in 1995 - IPC

Abstract RU 2030459 C1

FIELD: metallurgy. SUBSTANCE: as gas-slag-metal emulsion reaches furnace throat, blowing tuyere is lowered and fluorspar is added in the amount of 0.63-0.94 kg per ton of metal charge. First portion is added simultaneously with lowering of the tuyere while subsequent ones, after a time interval of 97-109 s provided the level of gas-slag-metal emulsion has reached the level of the furnace throat.
