- 摘要:
- 整体叶盘可以有效地提高航空发动机的性能和使用寿命,因此整体叶盘的精密铸造技术受到了广泛重视。主要针对某发动机整体叶盘的精铸过程中产生的冶金缺陷,并结合计算机模拟分析,对该叶盘的铸造工艺进行优化改进。结果表明,有效地控制了叶片欠铸、疏松等冶金缺陷,提高了产品合格率。Turbine blisk with whole integral shroud can effectively improve the performance and service life of aero-engine,as a result,the investment casting technology of the turbine blisk had been paid much attention.The metallurgical defects of a turbine blisk with whole integral shroud of the investment casting process were mainly aimed at,and the investment casting process was optimized and improved with the combination of computer simulation analysis.The results show that the metallurgical defects such as misrun and porosity are effectively controlled,and the qualified rate of the product is improved.
