摘　　要：针对含钒钢渣中钒回收问题,研究了铁平衡条件下碱度对钢渣中的钒和磷的影响。试验结果表明:碱度大于1.8,磷固溶于硅酸二钙相,钒固溶于硅酸二钙相和RO相中;碱度在1.3~1.5,磷大量溶于液相,少量固溶于正硅酸盐固溶体相,钒集中在尖晶石相;碱度为1时,磷集中在液相相中,钒大部分富集于尖晶石相,一部分溶解于液相。For the recovery of vanadium from V-bearing steelmaking slag, the paper focuses on the effect of binary basicity on the distribution of vanadium and phosphorus in steelmaking slag. The experimental results show that the basicity is greater than 1. 8, phosphorus dissolved in dicalcium silicate, and vanadium occurs in dicalcium silicate and RO phases; basicity is between 1.3 - 1.5, most of phosphorus dissolved in the liquid phase, a small amount in the solid solution of orthosilicate, and vanadium concentrates in the spinel phase; when the basicity is 1, phosphorus exists in liquid phase, most of vanadium enriched in the spinel phase, a part dissolved in liquid phase.
