- 摘要:
- 以实际低压铸造生产的 A356 铝合金大尺寸轮毂铸件为对象，对单浇道、双浇道和三浇道 3 种浇注工艺方
案进行了充型和凝固模拟。 根据模拟结果，分别对比了 3 个工艺方案的缺陷分布情况、充型效率、晶粒半径大小以及卷
气情况。 结果表明，三浇道工艺不仅提高了轮毂质量，减少了缺陷，而且大大缩短了生产时间，是有潜力的新工艺。
The filling and solidification of large-size A356 aluminum alloy hub castings produced by low pressure casting were simulated for three pouring process schemes, namely, single runner, double runner and triple runner. According to the simulation results, the defect distribution, filling efficiency, grain radius and entrainment of the three process schemes are compared. The results show that the triple runner process not only improves the quality of the hub and reduces the defects, but also greatly shortens the production time, which is a potential new process.
