大型筒体铸件采用ZL101A铝合金材料铸造

筒体总长1 410mm

直径为615mm

质量为223kg

铸件表面不能有夹渣、针孔、缩孔、缩松等缺陷

并且需要承受FS6气密性检验。该筒体铸件结构复杂

尺寸大

壁厚不均

铸造热节偏多

容易产生铸造缺陷。通过对大型铝合金筒体铸件的分析

总结出一套有效地提高大型铝合金承压铸件检漏合格率的有效方法。

Large cylinder with 1 410mm in length and 615 in diameter and 223kg in weight was produced with ZL101Aaluminum alloy

which required high technical condition and casting quality.It is not allowed for slag inclusion

porosity

shrinkage hole

shrinkage on the surface of casting

and it is subjected to FS6in the air seal test and 1.22MPa pressure in the water seal test.Cylindrical structure is complicated with big size

uneven wall thickness

so there exists many hot spots

leading to easily generate the casting defects.Through the development of large aluminum alloy cylindrical castings

a set of effective methods to improve the qualified rate of leakage detection of large aluminum alloy casting bearing pressure were presented.
