【Abstract】 The coupled turbulent flow and temperature fields were simulated by finite element method. The interaction between casting speed and flow, temperature fields were also analysed. The results not only give the changing tendency of heat flux between roll and molten pool, but also give the changing tendency between heat flux and casting speed. The results were compared with the experimental results. The surface temperatures of the casting strip were also given, together with the its changing with the casting speed.更多还原
