摘　　要：镁合金对杂质十分敏感,其熔体纯净度直接影响材料的性能和零部件的服役寿命。分析镁熔体中夹杂的主要类型及其来源,重点对熔剂法、过滤法、沉降法、稀土净化法及超声场法等多种镁熔体净化技术的现状及发展进行综述,指出了无熔剂净化法是今后镁熔体净化技术的发展趋势。Magnesium alloy is very sensitive to impurities, and the purity of magnesium melt directly influences material properties and service life of components. The main types of inclusion and its source in magnesium melt are analyzed. Tile present situation and development of refining and purification technology of magnesium melt, such as flux method, filtering method, method of settlement, rare each purification method and the method of ultrasonic field are reviewed. Finally, it is proposed that the non-flux purification technology is the main trend of development for magnesium alloy melt.
