摘要

分析了镁合金壳体低（差）压铸造中缩松、偏析、裂纹、熔剂夹杂和气孔等铸造缺陷的形成原因

并提出了相应的解决措施。通过对浇注工艺、造型工艺及熔炼工艺等的严格控制

制定出合理的工艺方案

减少了铸件缺陷

达到I类铸件要求。

Abstract

The casting defects such as looseness

segregation

crack

flux inclusion and porosity in anti-gravity pressure casting magnesium alloy shells were analyzed.The corresponding countermeasures were put forward.Through strictly controlling casting process

molding quality and metal liquid quality

a reasonable process plan was designed to reduce casting defects

meeting Class I casting requirements.
