metallurgy, particularly, processes of prereduction and electric furnace steel making. SUBSTANCE: method includes charging of vanadium-containing ore material, for example, pellets into shaft furnace, pellets prereduction with their subsequent melting in electric arc furnace. Used for process of prereduction of vanadium-containing ore material in the form, for example, of pellets in shaft furnace are hot reducing gases produced in gasifier with liquid bath. Vanadium-containing semifinished product and slag produced also in gasifier are used as additional iron charge for melting process. EFFECT: low-cost production of steel alloyed with vanadium, increased concentration of vanadium in steel with the same relative consumption of vanadium containing materials. 3 cl, 1 dwg
