摘　　要：针对废铝原料中Si、Fe等夹杂元素含量高的问题，开展了熔剂法去除废铝熔体中si元素的工艺试验。熔剂组成为CaCl2、MnCl2和活性炭（质量比2：1：1），采用喷粉方式加入1％～1．5％熔剂，并维持30min的条件下，除硅率可达10％以上。Abstract： The experiments of Si element-removing from waste Al melting was developed by fluxing technology due to the problem of high content of Si, Fe and other inclusion elements in Al slag materials. The fluxing-agents includes CaCl2, MnCl2 and activated charcoal （mass ratio was 2：1：1）, and the fluxing-agents was added into the melting about 1%-1.5% by means of powder injection, and maintained 30 min, the ratio of Si element-removing above 10% was achieved.
