本文根据大孔出流理论。对环形横浇道系统的充填特性进行了研究与水模拟试验。结果表明:直浇道位于横浇道长度方向的中间比置于横浇道一端横浇道内流速小,内浇道流量大,对圆形铸件,内浇道径向引入和轴向引入比切向引入更平稳。
This article is based on the theory of macropore outflow. The filling characteristics of annular runner system were studied and the water simulation test was carried out. The results show that: the sprue is located in the middle of the runner length than the runner placed at one end of the runner in the runner flow rate is small, runner flow, radial injection of round castings, runners and the axial direction than the cut To introduce a more stable.
