摘　　要：采用倾翻炉进行两步法冶炼FeV80的工业试验,研究配铝系数、冶炼通电时间、精炼料、二次冶炼时间等参数对技术指标的影响,得出最佳冶炼工艺控制参数。结果表明:采用倾翻炉两步法冶炼能得到满足GB/T4139-2004标准中FeV80的要求,成分均匀,且刚玉渣的钒含量降低至0.6%以下,较一步法冶炼,刚玉渣钒含量明显降低,可直接作为弃渣;冶炼钒收率平均为96.5%,高于传统工艺。Industrial tests for two-step FeV80 smelting by tilting furnace were carried out to investigate the effects of the aluminum proportioning coefficient,power-on smelting time and refined materials on technical indicators and find out the optimized technical controlling parameters of smelting.The result shows that FeV80 alloy produced by two-step smelting process with tilting furnace meets GB/T4139-2004 standard,and is characterized by better composition uniformity.Vanadium content in the slag is noticeably decreased to lower than 0.6%,so the slag can be directly dumped as waste.Furthermore,the average vanadium recovery rate smelting is 96.5%,higher than that in the one-step process.
