| Abstract: | The solidification progress of sintering trolley body was simulated by View Cast software,and the location and cause of shrinkage defects were analyzed.Based on this,the size and position of risers was changed for process optimization and the reasonable casting process was finally designed.The result shows that the optimized technology can ensure castings progressive solidification and eliminate shrinkage and porosity.The productive practice indicates that the castings' microstructure produced by optimized technology is compact and the quality of castings meet technical requirement. |
