Abstract

This study deals with the solidification behaviour of cast iron with nodular graphite. By measurement of the “apparent shrinkage” the real feeding requirement can be determined under operating conditions. By means of cooling curves and measurements of dilatation the mode of solidification is established. The results are in accordance with today's knowledge of the morphology of crystallisation and offer an operating hypothesis for feeding technique in practice.
