On the Occurrence of Nodular Graphite in Cast Iron

Isao Aoki


Abstract:

Adding the Cu-Mg alloy to the molten pig iron, the alloy being the small particles in liquid state, dispersed in the molten pig iron (Fig. 4, 5, 6). When Si was added to the condition of molten pig iron as the inoculant, graphite in the molten pig iron precipitated on the surface of the liquid particles of Cu-Mg alloy and spheroidized (Fig. 9, 10, 11). Then, the Cu-Mg alloy dissolved mostly in the molten pig iron with time.
