The prediction of the solidification structure by means of calculations and simulation programs is of great importance for controlling the quality of continuous casting (CC) semis. Plant components, different process control options, and the chemical composition of the as‐cast product require optimized coordination of those factors to be able to set the optimum structure. As the simulation of temperature fields to predict the crater end during final solidification is already state of the art, the precise simulation of the solidification zones in CC semis is the important next step. Therefore, a circular arc caster is simulated with nucleation, grain growth, and sedimentation considered. The asymmetric as‐cast structure is calculated with a good accuracy providing a good base for the implementation of microsegregation in the next development step.
