Abstract
The integral casting process is the first choice for forming aeroengine parts with integrated design, for example, changing the welded or mechanically connected ring parts into an integral precision casting. Taking the integral investment casting of an aeroengine ring as an example, this paper analyzed the key problems of the integral investment casting process, such as melt filling, casting solidification defects and dimensional deformation, using numerical simulation technology, to provide a theoretical basis for the process design and optimization. The simulation and experimental results showed that the integral casting can not only meet the requirements of the casting forming, but also ensure the dimensional accuracy of the castings. The shrinkage porosity of the casting was effectively controlled by insulating the riser. Finally, the qualified castings were obtained.
