Beschreibung
Zusammenfassung:	FIELD: ferrous metallurgy, processing of vanadium-carrying pig iron to steel. SUBSTANCE: process of winning of vanadium-carrying slag includes pouring of vanadium-carrying pig iron into converter, feed of lime as calcium-containing material, of fluorite, addition of magnesium-carrying material, blowing-through of melt by oxygen from above through tuyere and tapping of slag from converter. Additives carrying magnesium and calcium are fed into converter in the amount that ensures ratio of components in vanadium- carrying slag within following limits: MgO:Ca0:P2O5=(20-75):(105-125.):1. EFFECT: increased degree of winning of vanadium from converter slag. 1 tbl
