rotational casting

基本解释

Technology of vertical centrifugal casting, the calculation for gate size and rotational speed of mold were introduced.
介紹了立式離心鑄造方法、澆口尺寸和鑄型轉速的計算。
Semi-centrifugal casting. The molds used can be permanent or expendable, can be stacked as necessary. The rotational speeds are lower than those used in centrifugal casting.
型模可以是永久性的或是消耗性的，可根據需要曡加。它的鏇轉速度比離心鑄造低。
It is suggested to apply the principle of effective gravity and equivalent pressure head to calculate the rotational speed and ingate area in the processing of grinding ball by centrifugal casting.
在離心鑄球工藝中，可應用有傚重度和等傚壓頭原理計算轉速和內澆口斷麪積。
