六辊精密冷连轧机带钢截面和边缘降调控性能研究

带钢截面和边缘降调控功效研究是板形控制技术的核心之一,也是冷连轧机板形自动控制系统模型的主要设计依据.以六辊精密冷连轧机为例,提出了包含各项影响因素和调控手段的冷连轧机截面和边缘降控制方程;通过有限元仿真计算得到了弯辊和窜辊等调节手段下的板形调控性能参数,其结果对冷连轧机辊形设计、弯辊窜辊工艺规程的制定,特别是对带钢截面、边缘降闭环自动控制系统的实现,具有重要的参考价值.

Study on Control Property of Strip Steel Profile and Wedge Drop in 6-High Precision Cold Tandem Mill

Study on control property of strip steel profile and wedge drop is one of important technologies for controlling plate shape, which is also the main basis to design automatic system model for it. Taking 6 - high precision cold tandem mill as an example, control equations of cold tandem mill profile and wedge drop including all kinds of effective factors and control methods are advanced, property parameters of plate shape control under roll bending and roll changing are computed and achieved by finite element simulation, and the results of which are valuable to design roll shape and make technique regulation for roll bending and roll changing, especially for realizing close hoop automatic control system of strip steel profile and wedge drop.
