摘要

倾转铸造生产ZL107铝合金进气管及用ProCAST模拟发现铸件上多处出现了缩松、缩孔

通过正交试验研究了模具预热温度、浇注温度、倾转速度、浇口杯预热温度对铸件缩孔、缩松缺陷的影响。结果发现

影响顺序为模具预热温度>浇注温度>倾转速度>浇口杯预热温度。最优工艺参数:浇注温度为740℃、上下模分别预热400℃和350℃、倾转速度为9.0°/s、浇口杯预热温度为300℃。对厚壁部位进行激冷、修改浇冒口结构并保温处理后

数值模拟发现优化后铸件的凝固顺序合理

缩松、缩孔消失

并进行了实际生产验证。

Abstract

According to the shrinkage porosity and cavity in ZL107 aluminum alloy intake pipe during the tilting casting and numerical simulation on ProCAST

the tilting casting process was optimized by orthogonal numerical simulation experiments to eliminate these defects. The results indicate that the influence of factors on shrinkage porosity present as follows: mould preheating temperature>pouring temperature>tilting speed>gate cup preheating temperature. The optimized tilting casting process parameters are as follows: pouring temperature of 740 ℃

preheating temperature of 400 ℃ and 350 ℃ for upper and lower mould

respectively

mould tilting speed of 9.0°/s

preheating temperature of gate cup of 300 ℃. After chilling the thick wall

modifying structure of riser system and insulation

the numerical simulation reveals that the solidification sequence of the casting is reasonable

and the shrinkage porosity and cavity disappear after optimizing

which is verified by practical production.
