Properties of Centrifugal Casting at Different Rotational Speeds of the
نویسنده
چکیده
Solidification rate of the casting affects greatly on the microstructure, quality as well as the mechanical properties of the casting. In centrifugal castings solidification rate is faster compared to gravity casting but still solidification depends on various process parameters like, die wall temperature, pouring temperature of the molten metal, wall thickness of the die and also rotational speed of the die. This paper describes the effect of rotational speed of the die on the rate of solidification of the centrifugal casting. At speed around 800 rpm casting shows fine grains and harder metal compared to the castings at lower speed. Keywords— Centrifugal casting, Hardness, solidification, wear, microstructure

Experimental Study on Cooling Rate of Centrifugal Casting Based on Grain Size
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 ce...
