Abstract
A numerical model has been developed to analyze the heat transfer, fluid flow and deformation behavior of solidifying shell in continuously cast round billet. The temperature distribution of the billet and the mold and the fluid flow pattern of molten steel were determined using finite difference method. The thermo-elasto-plastic stress fields in the billet and the formation of air gap along the mold wall were analyzed using finite element method. The heat transfer coefficient between the solidifying shell and the mold wall was calculated by coupling above two procedures. This model shows good agreements with the reported experimental results. The effects of fluid flow on stress fields have been simulated with the variation of casting and carbon contents. The effects of casting variables on the temperature distribution and the shell thickness were also predicted.
