摘要

根据机车电机水冷端盖铝外套的结构特点

进行了铸造工艺的设计及其优化。数值模拟结果表明

在铸件的热节处设置合适的环状冒口、暗冒口和冷铁

有效地改善了铸件内部缩孔、缩松问题。接着对铸造工艺进行了优化

将环状冒口高度降至90 mm

将暗冒口高度降至80 mm时

铸件的工艺出品率为51.6%

比优化前提高了14.2%。采用优化后的铸造工艺生产的铸件质量优良。

Abstract

According to the structural characteristics of the aluminum outer sleeve of the water-cooled end cover of locomotive motor

the casting process was designed and optimized. Numerical simulation results show that through setting the appropriate annular riser

blind risers and cold iron in the hot spot of the castings

the problem of shrinkage porosity in castings was improved effectively. Then the casting process was optimized. When the annular riser height was reduced to 90 mm

and the blind riser height was reduced to 80 mm

the process yield of castings reaches 51. 6%

improved by 14. 2% compared with that of un-optimized ones. The optimized casting process was applied to practical production with desirable quality.
