Mould filling of melt in vertical centrifugal casting is a complex process,
which is governed by a number of processing variables. In this paper, a
complete analysis of mold filling process of melt in vertical centrifugal
casting is accomplished by combining theoretical analysis, numerical
simulation and experiments. Results show that the melt fills the cavity with
varying cross-sectional area and inclined angle. The filling process is
divided into two steps in vertical centrifugal casting: forward filling and
back filling. The cross-sectional area decreases and the inclined angle
increases with increasing of the rotational velocity during forward filling.
Moreover, the filling process of liquid has been simulated based on SOLAVOF
technique. The comparison between the experimental and the
numerical results shows good agreement.
