摘　　要：根据Si、Al还原WO_3、MoO_3和FeO的△G^0-T图,论证了铝硅热法生产FeWMo合金的可行性。试验研究表明,影响W、Mo回收率的主要因素是单位炉料的热效应、还原剂比例及配比、石灰和萤石配比等,获得了含W35％左右、Mo30％左右的FeWMo合金,元素回收率达到ηw91.2%～92.8％、ηMo92.0%～93.8％。产品完全可以用于生产WMo系列合金钢。According to ΔG-T diagram of silicon and aluminium reducing WO3, MoO3 and FeO. It is proved that producing FeWMo alloy with aluminothermic -silicothermic process is feasible.Test study shows that main factors affecting recovering W amd Mo are unit thermal effet ,reductant proportion and burden ratio, lime to fluorite ratio etc.. FeWMo alloy bearing about 35% W and 30% Mo is produced and recovery are respectively ηw91.2-92.8%. ηMo2.0%-93.8%. The alloy can absolutely be used to produce series alloy steels.
