- 摘要:
- 对球墨铸铁汽车轮毂支架的铸造工艺进行设计,并利用MAGMA软件对汽车轮毂支架铸造充型和凝固过程进行数值模拟,预测了在铸造过程中可能产生的缩松、缩孔缺陷,并分析了缺陷形成的原因。结果表明,通过增设冷铁,增加铸件上端盖大尺寸区域的凝固速度,消除了铸件中缩松、缩孔缺陷。
The casting process of ductile iron automotive wheel hub support was designed,and the filling and solidification process of automobile wheel hub support was numerically simulated by MAGMA software.The possible shrinkage porosity and cavity defects during the casting process were predicted,and the causes of the defects were analyzed.The results show that by adding chills,the solidification speed of the large-size area of the upper end cover of the casting is increased,and the shrinkage porosity and cavity defects in the casting are eliminated.
