板形方程h=h(x)与辊系刚度K_R是实现板形控制所必需的模型。忽略出口带材的弹性恢复,出口板形与承载辊缝形状应该相同。板形的计算理论有弹簧模型、分割模型以及综合地使用弹簧模型与分割模型。这些弹性理论解给出了组成板形方程的主要成分如挠度、压扁等,能正确反映轧制条件对板形影响的规律。由于在力学解析过程中采用了一些假设与近似,降低了计算结果的精度;
The plate equation h = h (x) and the roller system stiffness K_R are the necessary models to achieve the plate shape control. Ignoring the elastic recovery of the exit strip, the shape of the exit plate and the shape of the carrier nip should be the same. The computational theory of plate shapes includes spring models, segmentation models, and the integrated use of spring models and segmentation models. These elastic theoretical solutions give the main components of the plate equation, such as deflection, flattening, etc., which can correctly reflect the influence of rolling conditions on the plate shape. Because of the assumptions and approximations adopted in the mechanical analysis, the accuracy of the calculation results is reduced.
