| 摘 要： | 在带钢热连轧平坦度控制系统中,平坦度实测信号通常包含精轧后带钢横向温差引起的附加干扰.针对鞍钢ASP1700热连轧机组,利用红外热像仪测量精轧后带钢横向温度场.通过具体分析温差附加干扰对带钢平坦度控制的影响,采用最小二乘法拟合得到带钢横向温度场分布规律,建立了平坦度控制目标设定的温差补偿模型. |

| Abstract: | In the flatness control system of hot strip, measured flatness signals usually contains additional signals caused by temperature difference along the lateral direction of the hot strip after rolling. The lateral temperature of the hot strip was measured by a kind of thermovision in ASP 1700 hot strip mill in AnSteel, China. By analyzing the influence of the temperature differece on the flatness control system of hot strip, the lateral temperature field distributing law was obtained based on the least square method and a temperature compensating model for the control target of strip flatness was set up at the same time. |
| Keywords: | hot strip mill temperature field flatness least square method |
