摘　　要：分析了中厚板轧制过程中弹跳曲线零点漂移对轧制力自适应的影响,认为在忽略入口厚度波动对轧件塑性影响的前提下,轧制力模型的自适应不受弹跳曲线零点漂移的影响。但如能根据实际生产需要用辊缝零点自适应的方法来计算辊缝零点漂移量,从而消除入口厚度波动对轧件塑性的影响,则可进一步提高轧制力的自适应精度。该方法在实际生产中取得了较好的应用效果。The influence of zero wave for spring curve of plate mill on rolling force adaptation was analyzed and it was proved that if the influence of wave of entry gauge on plate stress could be ignored, the influence of zero wave for spring curve of plate mill on rolling force adaptation also could be ignored. In order to eliminate the influence of wave of entry gauge on plate stress, the selfadaptation method of zero wave of spring curve is adopted. The method was used in online control and the effect was well.
