摘　　要：从提高铝镁合金铸件质量出发，分析研究了冷硬树脂砂的工艺特点，采用冷硬树脂砂铸型和差压浇注等工艺方法，获得了优质铸件。现场浇注铸件测试结果表明，铝镁合金铸件精度可达ＣＴ７～９级，表面粗糙度Ｒａ＝４．５，铸件无内部缺陷。Technological features of cold hardening resin sand are studied from the viewpoint of improving the quality of aluminium and magnesium castings. It is pointed out that the employment of cold hardening resin sand moulds and the adaptable pressure pouring method are much beneficial for the improvement of external and internal qualities of above castings. And the castings of superor qualities can be produced. Tests on the castings indicate that the precision reaches above CT7～9 and surface roughness reaches to Ra=4.5 and there is no internal defect.
