摘　　要：基于中厚板轧制过程的实际情况 ,提出实测温度的几种处理方法 :(1)采用有限差分法分析钢板厚度方向的温度分布 ,并提出钢板表面温度与平均温度差值的变化规律 ,从而使实测温度合理应用成为可能 ;(2 )提出一次开轧温度和二次开轧温度的自学习算法 ;(3)结合实测轧制力来确定实测温度的误差范围。采用这些处理方法后 ,可以将实测温度的预测误差控制在± 15℃。Based on the plate rolling process,some treatment methods about measure temperature are analyzed. The distribution of plate temperature in gauge direction is analyzed by the finite difference method and the variation rules of the difference of surface measure temperature and average temperature is got. The self-learn algorithm of the first the second start rolling temperature and is presented. The determination method of error limit of measure temperature is put forward based on the measure rolling force.According the above methods, the prediction error of measure temperature can be decreased to ±15℃.
