Abstract
A mathematical model to calculate the hot cracking tendencies during D.C. casting is described. The model combines a new simplified thermal model for D.C. casting with the concept of solidification shrinkage not eliminated by afterfeeding (Feurer) and the concept of the critical time interval during solidification (Clyne and Davies). This model is able to calculate hot cracking tendencies regarding the effects of composition, casting rate and ingot diameter. In spite of the absence of sufficient physical and solidification data it is shown that there is a satisfactory degree of correlation between prediction and practical casting knowledge.
