| 摘 要： | 介绍了带钢热连轧机组温度模型以及目前常用的温度模型自学习方法.针对目前常用的温度模型自学习方法的不足,提出了一种分区补偿法用于温度模型自学习,该方法按一定的分配系数将终轧温度偏差分配到各冷却区段,温度偏差分配系数可以根据各机架轧制力情况进行调节,所以在保证终轧温度预测精度的同时,也提高了轧制力的预测精度.这种新型的温度模型自学习方法被成功地应用于天津荣程750 mm精轧机组,取得了较好的应用效果.

| Abstract: | The temperature model of hot strip finishing mills in tandem was discussed,as well as the conventional self-learning strategy relevant to it.To rise above the defects in the conventional self-learning strategy,a zonal compensation method is applied to temperature model self-learning,where the finish rolling temperature errors are assigned to each cooling zone according to certain temperature distribution coefficients,which can be readjusted according to the rolling force of each and every stand.In such a wa... |
