Melting of metals, during a casting process involves an enormous amount of heat transfer from source to the raw material. Study of heat transfer, although helps in optimum utilization of power, practically it is a very difficult task owing to high temperatures. This paper reports an attempt to perform computer aided analysis of heat transfer/temperature distribution in an Electrical Resistance Furnace (ERF) and experimental validation of the same. Several novel techniques were used to serve the purpose. Lead, with a melting point of 327 ºC was used for simulation and experimental validation. The experimentation involves the placement of thermocouples in planned locations in the furnace, in the crucible and within the metal during the melting process. On similar lines, monitoring points were considered during the computational technique. The simulation was carried out using ANSYS’s Icepack module. The results indicate the suitability of the software-based computational/simulation technique for the melting process with an error of up to 20%, depending on the location of the thermocouples/monitoring points. The correlation of experimental vs. simulated values was very high in metal (R2=0.990 to 0.995) and lower (R2=0.635 to 0.666) in air.
