| Abstract: | Based on the principle of smooth filling casting system without gas gap,the casting system of bolster is designed.The filling and solidification process is also simulated.Comparison of the filling simulation results,it is found that there are no gas entrapment,turbulent flow and sputtering during the new casting process.According to the simulated temperature fields and solid fraction,the hot spot and shrinkage porosity are not found in the bolster casting,so the new casting process is feasible. |
