Centrifugal casting machine speed selection

centrifugal casting machine speed selection Selection of centrifugal casting machine speed, the main consideration should be given to two issues:

(1) the centrifugal casting speed at least should ensure that the liquid metal into the mold immediately after the formation of cylinder, around the axis of rotation;(2) make full use of the role of centrifugal force, ensure the quality good casting, avoid the shrinkage hole and shrinkage porosity, inclusion and porosity of castings. Produced by centrifugal casting, defect should also pay attention to the type and liquid metal wall with centrifugal too much pressure caused by the expansion of sand adhering sand castings.
