摘　　要：针对回收铝原料中Fe、Si等夹杂元素含量高的问题，开展了熔剂法去除废铝熔体中Fe元素的工艺试验。熔剂的组成为硼砂、硫磺和氯化锰（质量比2：1：1），加入量为1％～1．5％并维持30min左右时间的条件下，可以达到较好的除铁效果。Due to the problem of high content ofFe, Si and other inclusion elements in A1 slag materials, the experiments of removing Fe element from waste A1 melting by means of fluxing technology was developed. The results show that the compositions of fluxing-agents included borax, sulphur and MnC12 （the mass ratio was 2：1： 1）, the amount of fluxing-agents added into the melting was about 1%-1.5%, maintained 30 min for carrying on the reaction between fluxing agents and Fe inclusion of A1 slag melting, can achieve good effects of Fe element-removing.
