根据矫正辊辊形理论 ,分析了矫正机在矫正不同钢管直径时 ,管件与辊面的接触状态 ,并运用约束非线性优化工具对辊形半径偏差进行了优化 ,使角度调整达到最佳化。辊角最优化设定曲线为实际操作提供了依据 ,对提高矫正质量具有指导意义 According to the corrective roll theory, the contact state between the tube and the roll surface was analyzed when the straightening machine was calibrating the different diameters of the steel tubes. The constrained nonlinear optimization tool was used to optimize the deviation of the roll radius so that the angle adjustment was optimized. The optimal setting curve of roll angle provides the basis for practical operation, which is instructive for improving the quality of correction
