Industrial Experiment of FeV80 Smelting with Two-step Process

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.
