高铝锌基合金离心铸造缺陷分析

Study on Defects in Centrifugal Casting of Zn-BaSe Alloy with High Al-Content

本文考察分析了高铝锌合金离心铸造时易产生的表面缩陷和皮下缩松、内部夹杂和气扎等缺陷的产生原因和影响因素,从而提出了防止这些缺陷的途径。

In the paper it has been investigated that the formation reasons of the defects such as suface shrinkage and shrinkage porosity, inclusion and gas-hole which are Liabe to form in centrifugal Casting of Zn-base alloy with high Al-content and the cast variables infuencing on these defects Based on the above, the way to pretect from the defects has also been raised.
