Various pig irons were melted in air and held for various duration in the vacuum state at 1773 K to 1823 K. The total oxygen and that dissolved were measured. Then the melt was treated by Fe-Mg-Si and Fe-Si-Ca alloy. After the nodularizing reaction, the melt was poured into green sand mould with a thickness of 2 mm, 6 mm, and 15 mm. The graphite nodule counts were measured and structures in the sections were observed. The relationship between the nodule count and oxygen content was studied. Two mm thick sections were made without chill structures because the removal of the oxygen corresponds to the oxygen content in melt. In order to obtain the maximum graphite nodule count in the 2 mm thick section, the optimal amount of Mg to be added exists.
