原镁直接熔炼生产镁合金压铸件的工艺进展

Developments in Technology for Producing Magnesium Alloy Die Casting Directly from Primary Magnesium

简述了我国镁合金压铸件生产现状,分析了从原镁到镁合金压铸件的工艺过程及存在的问题;讨论了全封闭式熔化及浇注集成化方法、合金化阻燃技术和半固态成形技术等三种工艺优化方法。

The current status of magnesium alloy die casting production in China is introduced briefly in this paper. Technological process from primary magnesium to magnesium alloy die casting,and existing problems,are analyzed. Three optimizing techniques, including full enclosed smelting & pouring integrated method, ignition proof by magnesium alloying technology and semi-solid forming technology,are discussed.
