摘要: 铸轧区金属(液态金属、粘糊状金属和冷凝壳)的流动为非均匀介质流动。在铸轧区温度场分析的基础上，推导了非均匀介质流动流函数控制微分方程，用有限元法求解该方程。给出了太原铝厂双辊倾斜式铸轧机在稳定生产条件下铸轧区金属的凝固传热和流动规律。

Abstract:The flow of metal in castrolling area (liquid metal, sticky metal and solid shell) is an uneven medium flow. By analyzing the temperature field in castrolling part, the controlled differential equation of the flow function for an uneven medium flow was studied, and the equation was extracted with FEM. In a steady production of the twinroller aluminum castrolling machine in Taiyuan Aluminum Plant, the solidification transmit heat and the flow of metal in castrolling part were analyzed.

Key words: flow function; continuous castrolling; FEM
