| 中文摘要: |
| 利用ProCAST软件对ZL108活塞零件的传统铸造工艺和改变冒口形状的2种新铸造工艺进行了模拟对比分析，以上小下大的冒口形状新工艺铝活塞效果更好。再对比模拟分析此冒口形状铝活塞在3组不同浇注温度下的充型凝固过程，最终确定保温冒口截面为上小下大和浇注温度为720 ℃是活塞的最佳铸造工艺。 |
| 英文摘要: |
| The software of ProCAST was used to simulation to comparative analysis of the traditional casting process and two new casting processes by changing the shape of riser of the ZL108 piston. The result showed that it played a good filling effect on the riser with small top and big bottom.Then by comparison to the filling and solidification process for the aluminum piston with this shape of the riser under three groups of different pouring temperatures the piston's best foundry technique was confirmed in which insulating riser's section was with small top and big bottom and the pouring temperature was 720℃. |
