| Abstract: |
During casting the cooling behaviour of materials depend on the heat flow through the mould and the alloy composition. Even the alloy composition is same; the cooling rate can change the properties of the materials. In the present study, an atempt has been taken to predict the cooling behaviour of gray cast iron into a resin bonded sand mould at various thicknesses using JL FEM analyser software. After that, to verify the predicted value, cast iron was melted and poured into the previously mentioned sand mould. Using K-type thermocouple, the temperature was measured after every 20 sec. Both, the computer simulated and experimentally investigated cooling curves show the similar nature. The microstructure also confirms that the cooling rate changes the structure of the cast iron from gray to white cast iron.
