摘要
根据发动机缸体的结构特点,在铸造ADC12铝合金成分的基础上,调节铝合金中Fe、Cu、Mn的含量,通过提高Fe含量,降低Cu含量来降低合金的成本,最后通过ProCAST软件对发动机缸体的充型凝固过程进行数值模拟。结果表明,根据铸件的温度场、充型流动情况、凝固场、固相率、铸件缩松、缩孔所在位置及孔隙率,模拟结果优化了铸件的压铸工艺参数。在浇注温度为680℃、模具初始温度为240℃、压射速度为12 m/s的条件下,调节成分后的发动机缸体模拟方案更优。
According to the structural characteristics of engine block,the cost of the alloy was reduced by adjusting the proportion of iron,copper and manganese in the aluminum alloy,increasing the proportion of iron and reducing the proportion of copper based on the composition of casting ADC12 aluminum alloy.Finally,the solidifination process of engine cylinder block was simulated numerically by the ProCAST software.According to the temperature field,the filling flow condition in the casting,the solidification field,solid fraction,casting shrinkage location of shrinkage cavity and porosity,casting die casting technology parameters were simulated and optimized.The results indicate that under pouring temperature of 680℃,mold initial temperature of 240℃and injection speed of 12 m/s,the simulation engine block after adjusting composition are satisfied.
