前言目前,我国在镁合金铸件生产上大都采用钢丝绒过滤法来消除或减少在熔炼与浇注过程中所产生的氧化夹渣与熔剂夹渣。但由于钢丝绒的粗细均匀度与放置孔隙度不易控制,降低了钢丝绒的滤渣效果。近年来,在镁合金铸件生产中,国外广泛采用了“标准过滤网”过滤 Preface At present, most of the magnesium alloy casting production in our country uses steel wool filtration method to eliminate or reduce the oxidation slag and flux slag generated in the melting and casting process. However, due to the thickness uniformity of steel wool and placement of porosity is not easy to control, reducing the effect of steel wool residue. In recent years, magnesium alloy casting production, extensive use of foreign “standard filter” filter
