摘要：
Based on the thermodynamic calculation, the reductants to reduce V2O5 were selected, 0.1% V were added into steels by reducing V2O5 during the smelting process. The yielding rate of vanadium was calculated by chemical analysis data. The yielding rate is 98.17% when using Si+20%C as reductant and is about 94.94% when using Al+Mg as the reductant. By comparing the inclusion morphology and composition, contrasts the Brinell hardness and tensile strength of steels using different reductants, it was found that when using Si+20%C reductant, the inclusions in the steel is larger in amount, smaller in size and higher in Brinell hardness and tensile strength.
