The continuous casting process of different steel grades is the casting process used to produce different grades ofsteel without stopping the operation. In this study, an analysis model for which a solidification phenomenon,mixing phenomenon and turbulence taking place inside the mold and the bloom in a continuous castingprocess of different steel grades were all considered was developed. Based on the comparison betweenthe analysis results of the analysis models for implementation of each phenomenon, an analysis modelsuitable for analysis of the phenomenon taking place in a continuous casting process of different steel grades wasselected. A three-dimensional analysis model was completed by combining the selected optimum analysismethods, and its accuracy was verified by comparing the present numerical result with the result of the experiment. Theresult of the numerical analysis conducted using the selected model showed that mixing the different grades ofsteel was promoted and the mixing length was increased by the three-dimensional characteristics of the flowgenerated inside the mold. The mixing length in the bloom was predicted after the two grades of steel weremixed completely.
