摘　　要：板凸度是热轧带钢产品质量的重要指标之一,板凸度闭环控制能够有效地保证板凸度精度。以弯辊力调节作为板凸度闭环控制的主要手段,以保证板形良好为前提,给出了板凸度闭环控制策略及弯辊力对板凸度传递系数的计算方法,建立了板凸度闭环控制模型。通过在宁波钢铁公司1780热连轧机组的工业应用,经过实际考核,带钢板凸度命中率达到96%以上,同时能够保持板形良好,取得了较好的控制效果。The strip crown is an important indicator of the quality for hot strip;the strip crown closed-loop control is an effective means to ensure the strip crown accuracy of hot strip.Under the condition of good flatness,through adjusting bending force as the primary means of the strip crown closed-loop control,the strategy of strip crown closed-loop control and the calculated method of bending force transfer coefficient on the strip crown were present.The model of strip crown closed-loop control was established.The strip crown closed-loop control system was used successfully on finish stands of Ningbo Steel 1780 hot strip mill.Through the actual assessment,the strip crown hit rate reaches above 96% and strip shape is good.
