摘要

在常规压铸工艺条件下

利用自行设计的薄壁件压铸成形模具研究了熔体处理工艺对ADC12铝合金薄壁成形性能的影响。结果表明

铝熔体综合处理可显著提高铝液纯净度

除杂率高达92%

而100g铝含氢量仅为0.16mL

有效改善了杂质相形态

平均晶粒尺寸仅为52μm;良好的熔体品质降低了铝液粘度

有效提高了铝液的薄壁充型能力

与常规熔体处理工艺相比

可完全充型的最小壁厚减小了33%。

Abstract

Effects of the melt treatment on the thin-wall processability of ADC12 alloy were investigated by the help of self-designed thin-walled die casting die in the condition of conventional die casting.The results reveal that the integrated melt treatment of ADC12 alloy can geatly improve the purity of melt and change significantly morphology of impurity and refine the average grain size to 52 μm

in which ratio of inclusion-removal reaches up to 92% and hydrogen content only is 0.16 mL/100 g.The desirable melt quality can effectively improve the filling capacity of the thin-walled die casting by decreasing viscosity of aluminum alloy melt.Comparing with the conventional melt treatment

the minimum wall thickness which realizes full filling can increase 33% after integrated melt treatment.
