摘　　要：在板形检测过程中,针对冷轧带钢两侧边部经常不能完全覆盖检测通道及可能发生偏移的现象,建立了适应在线计算的带钢边部板形信号误差补偿模型。利用该模型,根据带钢横向偏移量自动计算检测辊的起始通道号、有效通道数量及带钢边部的通道覆盖率,合理选择比例补偿和差分补偿2种方法,对带钢边部在线板形信号进行必要的误差补偿,使板形曲线更真实地反映实际板形状况。经物理测试和工业验证,该方法可靠有效,有效防止因异常板形信号引起的误调事故,满足轧机的精细板形调控要求。In the shape detection process of the cold rolling strip, the strip edges on both sides often couldnt completely just cover a complete shape detection channel, so the edge shape error compensation model was established for this phenomenon. Using the model, channel coverage of the edge portion can be calculated according to the lateral shift amount of the strip automatically. Combined with two methods of the proportional compensation and the slope compensation, the shape signal error can be compensated based on its reasonable edge portion of the cold rolling strip. Physical testing and industrial datum show the method is reliable and effective.
