本文建立了薄板坯连铸结晶器铜板的三维传热数学模型，特别是对结晶器铜板冷面的水槽和背板部分采用了交替配置不同的边界条件处理，利用Visual Fortran语言自编程序计算结晶器铜板温度场。发现结晶器铜板热面温度呈现云层分布，冷面呈现冰凌状分布。分析了各种工艺参数（拉速、铜板厚度、冷却水流速等）对结晶器铜板温度场的影响。典型位置上的计算结果与现场测量数据符合较好，为优化生产工艺参数和结晶器设计提供重要的理论依据和实际参考数据。
A three-dimensional heat transfer mathematical model has been developed for the cooling copper plate of the thin – slab continuous casting mold. Alternative boundary conditions are applied for the cooling slots and back plate of mold copper plate cold face. The self -developed computer code is used to calculate the temperature field in visual Fortran language. The temperature distribution temperature in heat face of mold copper plate is cloudy –shaped, and cold face is ice columnar. The influence on mold copper plate temperature fields of operational parameters (casting speed、copper plate thickness、cooling water velocity) are analyzed. Calculated typical positions temperature agrees well with the measured temperature. These results are the important theoretical base for the process control and optimization of mold design.
