- 摘要:
- 离心滤座是军用发动机重要部件的组成部分,多年来其铸造成品率较为低下,不能满足生产的需求。通过优化铸造工艺,重新设定浇注系统,合理的放置补缩冒口,对容易出现缺陷的部位进行有效的补缩,提高了铸件的成品率,使生产进度得以保障。Centrifugal filter was an important component of military engine, and its casting yield was low for many years, which can not meet the needs of production. By optimizing the casting process, resetting the casting system and placing the feeding risers properly, the parts prone to defects can be effectively filled, the yield of castings can be improved and the production schedule can be guaranteed.
