Direct Alloying

The basic thermodynamic analysis of silicothermic reduction during direct alloying to smelting vanadium steel with V2O5 was discussed in this paper. The high-temperature carbon tube furnace and medium frequency vacuum induction furnace were used to study the phase compositions of the reduction products and the change law of the yield of vanadium when V2O5 was reduced by ferrosilicon. The research shows that the main phases of the silicothermic reduction products were VSi2、FeVO4 and Ca2SiO4 under the condition of using CaO to restrain the volatile of V2O5. Yield of vanadium was gradually improved with the increase of ferrosilicon during the direct alloying. The yield of vanadium in the steel is as high as 95.25% when the addition of ferrosilicon is 35%.
