Description
Summary:The continuous casting process of different steel grades is the casting process used to produce different grades of steel 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 casting process of different steel grades were all considered was developed. Based on the comparison between the analysis results of the analysis models for implementation of each phenomenon, an analysis model suitable for analysis of the phenomenon taking place in a continuous casting process of different steel grades was selected. A three-dimensional analysis model was completed by combining the selected optimum analysis methods, and its accuracy was verified by comparing the present numerical result with the result of the experiment. The result of the numerical analysis conducted using the selected model showed that mixing the different grades of steel was promoted and the mixing length was increased by the three-dimensional characteristics of the flow generated inside the mold. The mixing length in the bloom was predicted after the two grades of steel were mixed completely.
