摘　　要：介绍了电铝热法生产80钒铁反应过程的研究,对原辅材料中的硅含量及反应过程接触的含硅物料进行梳理及跟踪。结果表明,在铝热法和电铝热法生产80钒铁过程中,物料中的硅和氧化硅能被铝还原从而进入合金中,造成合金中硅含量较高。The reaction process of producing 80 FEV by electro-aluminothermic process is studied.The silicon content in raw materials and auxiliary materials and the silicon containing materials contacted in the reaction process are combed and followed.The results show that in the process of producing 80 FEV by aluminothermic process and electro-aluminothermic,the silicon and silicon oxide in the contacted materials can be reduced by aluminum and then enter the alloy,resulting in high silicon content in the alloy.
