小孔径三维扭曲弯管高温合金精密铸造工艺研究
Research on precision casting process of 3D distorted superalloy bent pipe with small-aperture
摘要
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.关键词
