RESEARCH ON THE SLAG PHASE TYPE OF VANADIUM-TITANIUM MAGNETITE IN PRE-REDUCTION -ELECTRIC FURNACE SMELTING

摘要

For the comprehensive recovery of V. Ti. Fe in vanadium-titanium magnetite in the process of pre-reduction-electric furnace smelting, it is expected that vanadium oxide is reduced into molten iron and titanium oxide is available in the slag. Thus the effect of slag basicity, the content of MgO, MnO and CaF_2 of slag content on the separation of slag and molten iron and the comprehensive recovery of V, Ti, Fe were investigated.
