<p> Correlation relationships between graphite nodule count evaluated by casting experiment and equilibrium amount of chemical compounds calculated by thermodynamic calculation were investigated for clarifying the effects of graphite nodule count on the amount and formation temperature of nuclear products for graphite nucleation in spheroidal graphite cast iron melt. Graphite nodule counts of spheroidal graphite cast iron varied in additive amounts of calcium, aluminum, and sulfur were measured. The equilibrium phases in the cast iron melt with same chemical compositions were calculated at 1150℃ without graphite crystallization. The calculated melting points of oxysulfdie composed mostly of sulfides were higher than temperature of spheroidizing treatment. This suggests that the oxysulfide was suspended in the melt before pouring. Magnesium nitride was stable in temperatures below 1300℃-1350℃. When, the aluminum content was increased to about 0.02mass%, aluminum nitride was stable in temperatures below 1300℃-1380℃. There was a negative correlation between the graphite nodule count and amount of aluminum nitride although there are no correlation relationships between graphite nodule count and formation temperature and amount of oxysulfide, magnesium oxide and magnesium nitride.</p>
