Electrode heating effects on preparation of Al-65V alloy

电极加热对制备Al-65V合金的影响（英文）

In this study,Al-65V alloy has been produced by electrode heating for 3−15 min.The impurities content,microstructure and the vanadium content of the alloy in the slag are investigated.The results indicate that different heating time shows obviously impacts not only on the impurities and microstructure of AlV alloy,but also on the vanadium recovery rate of slag.The impurities contents of C,O and N are 0.085%,0.022%and 0.036%,respectively,which meet the commercial standard when the electric heating time is controlled to 10 min,and the content of vanadium in slag is 0.18%.

本文研究了电极加热制备Al-65V合金过程中得到合金产物中的杂质含量、微观结构和渣中钒含量的变化情况,电极加热时间控制在3~15 min。研究结果表明,不同的电极加热时间不仅对合金产物中的杂质含量和合金的微观结构有明显影响,而且对炉渣中钒的回收率也有显著影响。实验过程中,将电极加热时间控制在10 min时,得到的钒铝合金中的杂质碳、氧、氮含量分别为0.085%、0.022%和0.036%,合金成分满足商业化应用标准,同时,得到的炉渣中钒的含量为0.18%。
