摘要

针对某型航空发动机双层双向结构整体导向器铸件毛坯缩松缺陷超标问题，通过将华铸CAE仿真模拟结果与荧光、显微组织观察结果相结合进行分析，研究了双层双向整体结构导向器缩松缺陷分布形态和产生原因，制定了针对缩松缺陷问题的铸造工艺优化方案。结果表明，优化后工艺方案生产导向器缩松缺陷得到显著改善，关键部位冶金超标缩松缺陷已完全消除。

Abstract

Aiming at the problem of excessive porosity in the rough casting of a certain type aero-engine double-layer and bidirectional integral guide apparatus， the InteCAST simulation results， fluorescence detection result and SEM detection result were combined to understand the distribution and origination of porosity in the double-layer and bidirectional integral guide apparatus， and the optimization scheme of casting process for porosity was put forward. The results indicate that the optimized process scheme can significantly improve porosity of the guide apparatus， and excessive metallurgy porosity in key parts has been eliminated completely.
