STRESS-ANALYSIS IN SOLIDIFICATION PROCESSES - APPLICATION TO CONTINUOUS-CASTING

Calculations of thermal stresses in solidifying materials have been carried out using the thermal-elastoplastic finite element method. The temperature history in the process of solidification was calculated first by the temperature recovery method and then transferred to the MARC code for the stress analysis. The scheme was applied to a complete analysis of continuous casting of low carbon steel. According to the two-dimensional model, the predicted depth of the liquid pool showed good agreement with experimental measurement. The analysis results were compiled into temperature history, shell thickness, stress history, principal stress distributions, residual stresses and deformation.
