摘　　要：介绍了钒铝合金、钛合金的生产工艺及用途。针对一步法生产钒铝合金造成钒收率低的问题进行了研究。结合试验结果,分析了反应速率、原料组成、冶炼时间对钒回收率的影响。得出:在现有条件下,V_2O_5与V_2O_3配比为4︰1,通电冶炼时间6 min时,钒回收率最高达93. 16%。该成果为钒铝合金冶炼提供了技术支撑。The production technology and application of vanadium aluminum alloy and titanium alloy are introduced. The problem of low vanadium yield caused by one-step production of vanadium aluminum alloy is studied. Combined with the test results,the effects of reaction rate,raw material composition and smelting time on recovery rate of vanadium are analyzed. The results show that under the present conditions,when the ratio of V2O5 to V2O3 is 4∶ 1 and the smelting time is 6 minutes,the highest recovery rate of vanadium is 3. 16%. The results provide technical support for smelting vanadium aluminum alloy.
