In earlier research work, a model of volume change during the solidification of S.G. iron was proposed and the effect of the eutectic growth was discussed in detail. With the proposed model some calculations have been made to simulate the volume change and the influence of process parameters, such as inoculation, pouring temperature, heat transfer coefficient a nd section size of casting on the volume change during the solidification of S.G. cast iron in the present paper. The same trends as known from foundry practice can be seen qualitatively and quantitatively.
