Summary

In the first section of this paper, a brief description of the model and its implementation are given. The 3-D model is based on the general purpose software Abaqus and uses a thermomechanical approach to describe the process taking into account the viscoplastic behaviour. It delivers the contraction of the rolling faces, the butt curl during the transient casting phase and the final ingot geometry. Also, strain rate and stress field at the end of casting are calculated. For evaluation and adaptation of the model to specific boundary conditions in a cast house, a production mold and bottom block system is chosen in order to compare calculations and corresponding casting trials on measured temperatures, curls and ingot geometries, which are finally presented.
