Abstract
According to the forming theory of investment castings with complex thin-walled structure
ZTA15 hollow flange structure and casting difficulties were analyzed.The design of casting process
numerical simulation and process optimization were carried out.The results show that the simulated results can predict the location and type of defects
and shrinkage porosities(gas holes)in the upper and lower flange casting can be reduced significantly through the optimization of casting process.High-quality titanium alloy castings were obtained by improving the quality.
