Simulation of microstructure of as cast

This study focuses on the development of advanced computational models aimed at simulating the continuous casting processes in metallurgy. The primary objective is to enhance heat transfer models that can operate under transient casting conditions, thereby improving the overall control of the casting cycle. In this research, two three-dimensional heat transfer models—TEMP-SIMU3D for steady state conditions and DYN3D for transient conditions—were developed. These models are designed to work iteratively in conjunction with a solidification and phase transformation model (IDS), enabling the prediction of microstructural evolutions during the casting process. Key results indicate that these simulations can accurately forecast phase transformations, microstructure properties such as dendrite diameter and austenite grain size, and even hardness distribution in the as-cast product. The incorporation of empirical equations into the model enhances the predictive capabilities regarding the quality of continuously cast products. Collaboration with the University of Jyväskylä on model development underscores the research's broader academic significance and practical applicability in metallurgy.
