Large - size symmetric three - roll bending machine 大型对称式三辊卷板机
An independent module of work roll bending compensation is set in the feedback control system 在反馈控制环节中专门设置一个独立运行的模块,即工作辊弯辊补偿控制模块。
Theoretically the varying contact rolling technology can increase the transverse stiffness of loaded roll gap , heighten the control effect of roll bending , improve the distribution of contact force between backup roll and work roll 从理论上分析了变接触轧制技术在提高承载辊缝横向刚度、增加弯辊力调控功效、改善辊间接触压力分布方面的作用。
The work roll bending on five stands are adjusted based on the periodical change of work roll shift position to decouple the coupling between edge drop and flatness control and obtain the optimum flatness control 该模块根据5个机架的工作辊轴向位置的变化周期性随动调整5个机架的工作辊弯辊,化解平坦度和边降的耦合关系,以获得最佳的板形控制效果。
