A method for production of vanadium-containing steel includes charge loading, melting, melt oxidizing, oxidizing slug removal, feeding of materials containing oxides of vanadium and desoxidant. After oxidizing slug removal the slag-forming agents are added on the heel of metal as follows: chamotte rubble, lime and calcium fluoride in the ratio 6:3:1 and in the amount of 5-15 kg/t of steel. After the slug-forming agents melting the GRES ash waste is introduced in the amount of 10-50 kg/t, with the ratio of slug-forming agents and ash waste 0.3-0.5, and the desoxidant is added after the melt holding for 3-5 min.
