摘要：A full-scale finite element model of a slab and its mold was developed to reveal the complex thermo-mechanical behaviors of slab in a vertical caster during continuous casting. An inverse algorithm was applied to calculate the heat flux and combined with the temperatures measured using thermocouples that were buried in different positions of the mold. The model was validated by comparing the calculated temperature with the measured ones. The results show that the thermal and mechanical states of the slab are not symmetric, reflecting the non-uniform nature of thermo-mechanical behaviors and hence the necessity of formulating a full-scale model. It will provide a helpful tool for further improving and optimizing the operation parameters for continuous casting slab.
