The InteCAST software was employed to simulate the solidification process of the casting tilting structure. The location of the shrinkage defects and cause under initial technology were analyzed. Based on this, the casting process was optimized. The simulation result shows that the sequential solidification of the castings can be ensured and the shrinkage can be eliminated in the tilting structure under new technology. The production practice indicates that the structure of tilting structure produced by new technology is compact and the tilting structure's technical requirement was satisfied.
