摘　　要：研究了Mn元素加入到Al 1 0Fe 0 6Si中对铝合金中富铁相杂质形态的影响,发现加入适量的Mn对铝合金中的富铁相形态具有很好的改善作用,通过不同锰铁比的合金在电磁场的作用下进行分离试验,结果表明当Mn和Fe的摩尔比为1 4～1 5时,电磁净化效果最为明显。并进一步验证了杂质的微观形态对电磁净化效果的重要性。The effect of Manganese on the shape of iron-rich phase impurities in aluminum has been studied by adding Manganese to AI-1.0Fe-0.6Si alloy. It is found that the moderately added manganese can reform the shape of iron-rich phase in aluminum in a much better way. According to the electromagnetic separation test of different proportions between manganese and iron, it is shown that the effect of the electromagnetic separation is the most obvious when Mn/Fe=1.4-1.5. The founding approved that it is important to control the microstructure of the impurities for the effect of the electromagnetic separation.
