摘要

采用AnyCasting铸造模拟软件

分别模拟了金属型倾转铸造铝合金和镁合金进气歧管工艺

并对其流动模式和释放热量进行了比较。镁合金熔液在整个充型过程中完全属于层流流动

铝合金熔液也属于层流流动。模拟结果显示铝合金与镁合金进气歧管的冷却曲线变化趋势基本一致

但镁合金熔液比铝合金熔液冷却时间更长。

Abstract

Flow behavior and heat release of aluminum alloy or magnesium alloy air intake manifolds during permanent mold tilting casting process were simulated by the Anycasting software. The results show that both magnesium alloy and aluminum alloy melt fully exhibit laminar flow during filling process. Cooling curves exhibit similar change shape for aluminum alloy and magnesium alloy manifold

however

solidification time of magnesium alloy melt is longer than that of aluminum alloy melt.
