首钢2230冷连轧机板形控制性能研究

Research on Strip Shape Control Technique in Shougang 2230 Cold Rolling Mill

研究了CVC辊形函数及等效轧辊凸度变化规律，建立了2230冷连轧机六辊CVC轧机辊形变形有限元模型，结合现场工况仿真分析了弯辊和窜辊等调控手段对辊缝凸度调节域、板形调控功效和辊间接触压力分布等板形调控性能指标的影响规律。

The CVC roll profile function and the variation of equivalent roll crown have been studied. A CVC roils deformation FEM model for 6-H mills in 2230 cold rolling mill has been established. The influence of roll bending and roll shifting on the adjusting range of roll gauge crown, the flatness control effect and the contact pressure distribution between rolls have been simulated.
