rotational casting

基本解释

Technology of vertical centrifugal casting, the calculation for gate size and rotational speed of mold were introduced.
介绍了立式离心铸造方法、浇口尺寸和铸型转速的计算。
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，可根据需要叠加。它的旋转速度比离心铸造低。
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.
在离心铸球工艺中，可应用有效重度和等效压头原理计算转速和内浇口断面积。
