| Abstract: | Fluid flow,heat transfer and solidification process of molten steel are very important to quality in the continuous casting of steel. With the high cost of empirical investigation and the increasing power of computer hardware and software,mathematical modeling is becoming an important tool to understand fluid flow phenomena. A mathematical model of fluid flow, heat transfer and solidification of molten steel was established. Numerical analysis on the macro-solidification process of C160 steel round billet in Magang was carried out. The numerical predicted results were good agree with the surface temperatures of round billet by direct measurement and break-out shell thickness in the mold, which shows that the mathematical model has highly reliability and accuracy. |
