摘　　要：随着我国对循环经济的日益重视,废铝的再生利用已成为铝工业发展中不容忽视的一个重要环节。回收废铝并用来重新制成铝坯料时,需要格外关注的是重熔熔体的精炼与纯净化处理。概述了LARS系统对铝熔体的精炼原理,并通过对其除氢、除杂效果的分析,总结出LARS技术在废铝回收领域的优势。As our country pay more attention to cyclic economy,lt will have to focus more on aluminum scrap recycling and aluminum second birth. Recycling aluminum for remaking aluminum products requires more careful attention to quality control during remelting and metal purification operation. The present paper analyses the refining principle of LARS （liquid aluminum refining system）, which is of unique ideas and improved structure; and based on the data of the refining effect on degassing and purification, summarizes the advantage of LARS in aluminum recycling.
