Abstract :
In this paper, a reasonable creep material model used in FEM analysis for bulging of cast slab was determined based on the comparative results between simulation and experimental data. A thermo-mechanical coupling, creep and dynamic FEM model of continuous casting process has been constructed and applied to case studies. The analysis produces outputs such as the necessity of considering the case slab movement for calculation of bulging, the inconsistency of bulging and the stress and stain rules of cast slab. The indications are that the results provide meaningful experiences for the calculation of slab bulging, and lay the foundation for further three-dimensional FEM analysis.
