摘　　要：针对辊式矫直机板形闭环控制收敛速度缓慢、导致矫直产品板形质量及成材率降低的问题。分析了辊式矫直生产中板带弹塑性变形机理和带材弯曲曲率半径与板形的函数关系,建立了压弯模型和弯辊模型,并通过解析法建立了辊式矫直机工艺参数预设定控制模型,该模型能有效提高板形闭环控制的收敛速度和控制精度,大大提高矫直产品板形质量及成材率。The slow convergence speed of the flatnessclosed-loop control for roller leveler,which leads to a decrease in the flatnessquality and yield of the rollerleveller.The elastic-plastic deformation mechanism of plate and strip in roller straightening production and the functional relationship between the strip-plate bending curvature radius and the strip-plate shape were analyzed.The bending model and bending roller model were established,besides,the pre-setting control model of the working parameters for the roller leveler was establish by the analytical method.This model can effectively improve the convergence speed and control accuracy of the plate shapeclosed-loop control,greatly improving the quality and yield of the straightened product.
