采用可控压力冒口消除球铁曲轴缩松缺陷

Using Pressure-Controllable Feeder to Eliminate Shrinkage Defect of Ductile Iron Crankshaft

根据可控压力冒口原理,选择适当的冒口和冒口颈尺寸,控制铸件内部压力,获得无缩松缺陷的铸件,并提高了铸件的工艺出品率。

By properly determining the dimensions of the feeder and its neck according to the principle of pressure-controllable feeder to control the inner pressure of casting,the shrinkageless casting was obtained,and the process yield of the casting was increased.
