Modelling and experimental investigation of solidification process in sand casting

This paper describes the simulation and experimental results of thermal analysis in sand casting process. Simulation model of 2-ingate mould and 3-ingate mould of sand casting are developed. The analysis was done by concentrating on chosen nodes as references. The change of temperature in the casting and sand with time was monitored. The heat was transferred from the casting to sand and from sand to surroundings. In order to verify the predicted results, experiments were carried out. Two types of experiments were carried out, i.e. 2-ingate mould and 3-ingate mould. The results revealed that the sand points of 3-ingate moulds give higher temperature than 2-ingate mould. For cast points, temperature of 2-ingate moulds dropped faster than the 3-ingate moulds. The temperature gradient was recorded in the casting cycle. The predicted results were then compared with experimental data and agreement between them was reported.
