摘要：
A comprehensive 3D mathematical model based upon the Abaqus software has been developed for the computation of the thermo-mechanical state of the solidifying strand during direct chill (DC) casting of rolling sheet ingots and during subsequent cooling. Based upon a finite element formulation, the model determines the temperature distribution, the stresses and the associated deformations in the metal. This paper concentrates on the non-uniform contraction of the lateral faces and shows comparisons between computed and measured ingot cross-sections after complete cooling. The influence of the mould shape and the contributions to this contraction are assessed as a function of the casting conditions.
