摘要
分析了大型铝合金圆环铸件在采用可倾转重力铸造时产生缺陷的原因,提出了改进方案。试生产表明,选取水平分型的重力金属型铸造工艺为批量生产的工艺,可以消除气孔、缩松(孔)等铸造缺陷,生产出合格产品。
The reason caused the defects of large aluminum-alloy ring casting with tilt-pouring process was analyzed, and some improving measurements were put forward. The trial production result shows that the casting process with horizontal parting, circular runner and separate ingates is more suitable for batch production. With this process the defects such as gas-holes and porosities can be effectively eliminated, and qualified castings can be produced.
