Abstract
The present work is based on a heat balance during the solidification of cast iron. Accordingly, an analytical expression was derived to relate the chilling tendency (CT) of cast iron to nucleation and growth processes associated with the eutectic graphite and cementite constituents. A relationship is found between the CT and factors such as the physicochernical state of liquid, the distribution of nucleation sites, and the density of nucleation sites for eutectic cells. In particular, it is found that the CT can be related to the critical casting modulus (M-cr), enabling determinations of minimum wall thickness for chilled castings or chill widths in wedge-shaped castings. Finally, the present work provides a rational for the effect of technological factors such as the chemistry of the melt, inoculation practice, holding temperature, and time on the resultant CT and chill of the cast iron.
