摘　　要：在热轧带钢层流冷却控制数学模型中，由于忽略带钢内部的热传导而使卷取温度控制精度不良。本文采用离线二维数模计算带钢沿厚度方向上的温度分布，在线控制中给予补偿，取得较好的效果。For the model of laminar cooling control of hot rolled strip,the accuracy of coiling temperature control is unsatisfactory because the heat transfer in the strip itself is ignored.In the paper,the two dimensional off line model was developed to calculate the temperature distribution in the thickness of strip.And,by compensating the effect of heat transfer in strip,good result of on line control has been obtained.
