Centrifugal Casting, Microstructure, Rate of solidification, Rotational speed
The rate of solidification affects the microstructure, quality and mechanical properties of the castings. The analysis of heat transfer in centrifugal casting is very complex due to rapid solidification, rotating mould, opaque mould and high temperature. As the grain size is directly depending on the rate of solidification of the casting, based on grain size the rate of solidification of the centrifugal casting can be determined. Grain size has been measured for the gravity castings at different cooling rates and using this result rate of solidification of the centrifugal castings have been determined which are produced at different rotational speeds.
