摘要：

The width of columnar grain zone in as cast strips is mainly determined by the length of columnar grains at nip point. Coupling temperature field, concentration field and micro growth, the simulation of the solidification structure on the solidification process of pure aluminum in water-cooled steel mould of twin-roll continuous casting was presented by CA-FE method in Procast. The model was built according to Cellular Automaton model and the locally functioned law of grain growth was established. By this model, the solidification of the single-phase pure aluminum was simulation and studied on the grain scale. By use of this model, the effects of process parameters on the solidification structure were studied. The calculation results fit the experimental ones well, and then the validity and the applicability of the model were tested.
