Abstract

In this paper, we
have provided the mathematical modelling of the conductive heat transfer in
horizontal centrifugal casting which was then used to analyze the temperature
distribution in centrifugal casting. The Finite Element Method (FEM) as a
numerical tool was used to discretize and analyze the temperature distribution.
The result obtained shows the temperature distribution both in the liquid cast
region and the mould region. The pouring temperature of the liquid cast into
the prepared mould was 15000C and
also to prevent thermal shock, the mould was preheated to a temperature of 2500C. After about 50 secs
when the liquid cast has been poured into the mould, the result obtained shows
a decrease in temperature from 1407.3477 0C
at a distance of 4.5cm to 1323.07720C at a distance of 6.5cm from the
centre
of the mould which is the interface between the liquid cast and the mould. Also
in the mould region, after about 50 secs, the temperature drops from 755.82520C
at 6.5cm to 350.62050C at 15.5cm from the
centre
of the mould. The maximum percentage error was 0.81996% and the minimum percentage error was 0.0000%. This comparison was made for the temperature distribution
in the cast region and the mold region after about 50 secs when the molten metal has been poured into the mold cavity.
This shows that the result obtained from this research is in agreement with the
result obtained from Exact Differential Equation Method (EDEM).
