摘　　要：针对镁合金熔炼过程常出现的气体、夹杂问题,介绍了几种传统净化工艺的发展现状,重点概述了几种新兴的非熔剂净化工艺,包括:超声净化法、电磁净化法以及真空净化法,并结合现状对镁合金净化技术未来的发展进行了展望。Aiming at the problems of the appearance of the gas and inclusions in the smelting process of magnesium alloys, the research state of some traditional refining processes were introduced, and then some emerging non-flux purification technologies, including ultrasonic purification method, electromagnetic purification method and vacuum purification method, were mainly summarized. Finally, the future development was prospected by combining with the present situation of mal^nesium alloy l^urification technologies.
