the mathematical modelling of the conductive heat transfer in horizontal
centrifugal casting. The model was then used to analyse the temperature
distribution in centrifugal casting. The Finite Element Method was used to
discretize and analyse the temperature distribution. Four quadratic element was
used to represent the entire domain of the casting and mould region
respectively. The result obtained shows the temperature distribution both in the
liquid cast region and the mould region. The liquid cast was poured into the
prepared mould at the temperature of <i>1500 <sup>0 </sup>C </i>and the mould was preheated to a temperature of <i>250 <sup>0 </sup>C </i> to prevent thermal shock. After about 20 secs when
the liquid cast has been poured into the mould, the result obtained shows a decrease
in temperature from <i>1388.7295 <sup>0 </sup>C </i>
at a distance of 4.5cm to 1032.8636 <sup>0 </sup>C at a distance of 6.5cm from
the centre of the mould. Also in the mould region, after about 20 secs, the
temperature drops from 755.8252 <sup>0 </sup>C at 6.5cm to 350.6205 <sup>0 </sup>C
at 15.5cm from the centre of the mould. The maximum percentage error was <i>1.6627% </i> and the minimum percentage error
was <i>0.0069%. </i> This comparison was made
for the temperature distribution in the cast region and the mold region after
about <i>20 secs </i> 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 finite difference
method. </span> <span style="font-size:12pt;font-family:’Times New Roman’, serif;"> </span> </p> <p> <br /> </p>}, number={1}, publisher={Nisantasi University}
