processing variables in vertical centrifugal casting machine technique
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.
