This study investigate the effect of Solidification process of thick-walled spheroidal graphite cast iron when controlling the cooling rate. The solidification analysis was done by Direct-Finite-Difference-Method using software for casting simulation, ADSTEFAN. The analytical model assumed a casting and had a sector of the outside diameter is 530 mm, the inside is 200 mm and the height is 300 mm (with five chills / without a chill). Casting the specimen based on the analysis model, compare the temperature measurement of the specimen with the result of the analysis. As a result, the cooling rate improved the model using chills. It's considering that chill affected the cooling rate.
