采用金属热还原热法制备V-Ti-Fe中间合金,考察V2O5与TiO2的加入比例、用铝量和Al-Mg合金用量对金属回收率和合金成分的影响.结果表明:最佳工艺参数为原料中V2O5和TiO2的质量比为0.5:1,实际用铝量为理论值的95％,Al-Mg合金用量为铝量的1/3.能谱分析结果表明,合金中的V和Fe元素分布比较均匀,Ti则存在一定偏析.为降低合金中Al和O的杂质含量,进行喷吹造渣精炼.精炼后,合金中的铝含量由4.27％降为1.86％,氧含量由2.10％降为0.91％.

V-Ti-Fe master alloys were prepared by metallothermie reduction method,and the influences of the mass ratio of V2O5 to TiO2,Al and Al-Mg alloy addition amounts on the metal recovery rates and alloy compositions were investigated.The results show that appropriate technological parameters are:the mass ratio of V2O5 to TiO2 is 0.5:1,Al addition represents 95％ of the theoretical value,and the Al-Mg alloy addition amount is one third that of the Al addition.The results from energy spectrum analysis show that V and Fe distribute uniformly in the prepared alloy,while the segregation for Ti,i.e.Ti-rieh phase is detected.A spray refining process was carried out to reduce the impurity contents of Al and O in the prepared alloys.The Al content drops from 4.27％ to 1.86％,and the O content drops from 2.10％ to 0.91％ after the refining process.
