通过在模具上加设水冷环以增强冷却速度

有效地减少了轮毂热节处的缩松、缩孔。优化后的工艺不但提高了铸件的性能而且缩短了生产周期

提高了生产效率。

Abstract

To eliminate shrinkage porosity occurred in the hot spot in low pressure casting large size aluminum alloy wheel

the ProCAST software was adopted to understand the temperature field distribution during filling and solidification process.The mould and casting parameters were optimized according to the simulation.The cooling rate was improved by adding water-cooling ring in the mould

and the shrinkage porosity in hot spot was reduced effectively.The results show that the optimized process not only improves the performance of casting but also shortens the production time

greatly improving the production efficiency.
