摘要

废铝原料中有较高含量的Mg元素带入到熔体中

造成化学成分无法达到要求。研究了熔剂法去除废铝熔体中Mg元素的工艺原理

并开展了工艺试验。结果表明

熔剂的组成为AlF3和MnCl2（质量比为1∶2）

加入量为1%

.5%

并静置30min的条件下

可以达到较为理想的除Mg效果。

Abstract

High Mg element content in Al slag materials could be brought into the melts to cause the chemical elements in the Al alloy composition not meeting requirements.The process of Mg element-removing from waste Al melting by fluxing technology was analyzed.The results show that with fluxingagents of AlF3 and MnCl2（mass ratio of 1∶2）and about 1%

.5% addition for 30 min

Mg elementremoving efficiency exhibits desirable.
