摘要冷连轧生产线多配备有1套或2套板形仪，用于板形的实时反馈控制以及板形质量的监测，各处所用板形仪的规格不尽相同。板形平坦度指标是表征冷轧带钢板形质量的重要参数，由板形控制系统根据板形仪检测结果自动提供，一般以IU(I-Unit)表示。为了更准确地表征带钢板形质量，分析了某冷轧常用板形控制系统中带钢平坦度的计算方法，并考虑板形仪传感器分布不均会对其平坦度计算结果造成的影响，在此基础上提出了利用线性插值构造间距均匀的横向伸长率分布模型的方法，对平坦度计算过程进行了修正，并以实际板形数据进行检验，结果表明修正后的板形平坦度计算方法不再依赖于板形仪传感器的布置方案，使得具有不同板形仪的冷轧生产线的板形质量更具可比性。

Abstract：Most of the tandem cold rolling mills are equipped with one or two flatness measurement device used for real-time control and flatness assessment of the strips. Distribution of transducers is different and uneven. Flatness index is an important parameter to characterize cold-rolled strips, which is provided by the automatic flatness control system and usually presented by IU (I-Unit). In order to express the flatness of strips exactly, the calculation method of an actual flatness control system provided by SIEMENS was analyzed, and the effect of uneven distribution of the transducers was considered. On this basis, linear interpolation was introduced to build an even and transverse elongation distribution model, and the formal flatness index calculation method was modified. Verified by actual flatness data, the new method was independent of the distribution of transducers, which improves the comparability of flatness of strip produced by different cold rolling mills.
