| 摘 要： | 发动机上小孔径三维扭曲弯管的机械加工、焊接、弯管机弯曲成型都无法实现，因此提出采用精密铸造技术研制K4202合金小孔径三维扭曲弯管的方法。结果表明，通过快速成型技术制造蜡模且采用特定的浇注工艺，浇注出的铸件质量满足设计和使用要求。

| Abstract: | Since 3D distorted superalloy bent pipe of rocket engine could not be obtained by ma- chining, welding and bender, the precision casting technology was proposed for development of 3D distorted K4202 bent pipe with small-aperture. The result shows that the quality of castings produced through rapidly prototyped wax mold and specific gating process can meet the requirements of design and application. |
