摘　　要：对板坯动态二冷配水原理进行了详细的分析和研究,通过板坯凝固坐标体系和凝固传热模型微分方程的建立,确立了连铸板坯二维非稳态传热数学模型的基本方程组,根据实际浇注条件依据目标表面温度控制原理动态地设定各二冷区水量,对铸坯表面温度进行在线控制,实现对铸坯温度场的优化,动态二冷配水对提高板坯质量发挥了重要作用。In this work, a detailed investigation and analysis on the slab dynamic secondary cold water distribution principle is carried out through the establishment of coordinate system of slab solidification and heat transfer model of differential equations, in order to establish the basic equations of two-dimensional unsteady heat transfer mathe- matical model of slab. Based on the actual casting conditions, according to the target surface temperature control principle by dynamic setting of the two district cooling water, on-line control of the surface temperature of billet is realized, billet temperature is optimized.
