摘　　要：作为金属液过滤技术,在砂型铸造过程中应用过滤网是一种比较成熟的工艺方法。过滤网的使用能够达到预防夹杂物等缺陷,为铸件质量的提升起到了非常重要的作用。但是,为了提高金属液净化效果,在应用过滤网的过程中还需要很多进一步研究的地方。因此,本研究从夹杂物的成因、滤网的净化机制、过滤网的作用和使用方法,以及过滤网残渣的危害等方面展开,以期能为铸造企业更合理应用过滤网技术提供借鉴。As a metal liquid filtration technology,the application of filter in the sand mold casting process has been relatively mature.Because the use of filter can prevent slag hole defects,it plays a very important role in the improvement of casting quality.However,in order to improve the effect of liquid metal purification,farther study is very necessary in the process of applying the filter.Therefore,this study investigates the formation causes of inclusions,the purifying mechanism,function and use method of filter,as well as the harm of filter residue,which will provide a reference for foundry enterprises to apply filter technology more rationally.
