Abstract:
Since 3D distorted superalloy bent pipe of rocket engine could not be obtained by machining, 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.
