On assessment of processing variables in vertical centrifugal casting machine technique
Abstract The aim of the present study is to investigate the influence of the vertical centrifugal casting machine technique over mechanical and metallurgical properties of a hypereutectic alloy. Due to the inherent vibration of the centrifugal casting machine technique, and in order to study and understand the individual effects of the equipment vibration and the centrifugal force itself (pressure or fluid dynamics), as well as the combined effect of both, three different tests were performed: gravity casting, gravity casting with vibration and centrifugal casting. It was concluded that the metallurgical and mechanical properties of castings obtained by the centrifugal casting process depend on the combined effect of the centrifugal pressure and/or fluid dynamics and on the inherent vibration of the technique itself. Correlations between the different casting techniques and obtained mechanical and metallurgical properties are presented.
