METHOD OF SLAG DESULFURIZATION Russian patent published in 2001 - IPC

Abstract RU 2164954 C1

FIELD: metallurgy; applicable in production of flux for electroslag remelting and electroslag welding and also in production of synthetic slag for steel or iron desulfurization. SUBSTANCE: introduced into liquid blast-furnace slag during its tapping is fluorspar. Then molten slag is blown with oxygen-containing gas and granulated. Consumption of fluorspar and oxygen-containing gas are determined by claimed rated relationships. EFFECT: ecologically sate production of slag with low content of sulfur by its combining with fluoride to obtain nontoxic gaseous compound SF₆. 1 cl, 1 tbl
