摘　　要：研究铝热法生产钨铁的反应过程,对偏析产生的原因进行了试验及总结。结果表明,加快钨铁合金冷却速度,有利于控制钨铁宏观偏析,但合金仍存在微观偏析。The reaction process of producing ferrotungsten by thermit method is studied,and the causes of segregation are tested and summarized.The results show that the accelerating cooling rate of ferrotungsten is conducive to controlling the macro-segregation of ferrotungsten,but the alloy still has micro-segregation.
