| Abstract Scope |
It is known that the estimation of interfacial heat transfer coefficient (IHTC) between ingot and mold is difficult due to the gap formation during solidification of steel melt. This study aimed to clarify the dominant factor of the IHTC between ingot and mold to obtain a simulation technique for ingot casting process with high accuracy. By means of the inverse problem analysis for the measured temperature transition of mold, the IHTC was estimated as 300W/m2K. Thereafter, the temperature transition of mold was simulated with a FEM software ProCAST using the obtained IHTC value. The simulated temperature transition was in a good agreement with the measured one. Then, the IHTC was also estimated in a different way with considering conduction and radiation theories. The estimation result corresponded well with the one obtained through the inverse analysis. Therefore, it was clarified that the IHTC in this study is dominantly controlled by radiation. |
