Abstract Casting SUS430 stainless steel with cooling nozzle that has proper homogeneous core size was simulated to investigate the optimum design of cooling nozzle. The results show that the cooling nozzle 190 mm in length and 20 mm in diameter is suitable when flowing air is used as cooling media. Preheating and a certain level of liquid in mould is necessary for casting. The superheat was reduced by 26 ℃ and equiaxed crystal ratio of 80% was obtained for 100 kg test.
