| 摘 要： | 结合现场带钢边降控制跟踪测试和工业试验,建立辊系三维弹性变形有限元模型,分析武钢1 700 mm四辊冷连轧机组引进的常规凸度支持辊与单锥度工作辊的辊形配置方案存在板形控制能力不足、边降控制效果欠理想和波动大等问题的原因.基于有限元仿真分析和工业试验,采用工作辊和支持辊一体化辊形设计思想提出自主设计的EDW边降控制工作辊配套的VCR变接触支持辊.研究结果表明,VCR/EDW新方案与原方案相比,前者的辊缝凸度调节域扩大10.7%,辊缝横向刚度增强19.1%,辊间接触压力峰值下降21.6%;VCR变接触支持辊配合EDW边降控制工作辊经过工业轧机现场轧制,轧机凸度控制能力明显增强,弯辊力调节效率提高,带钢边降、凸度及平坦度显著提高.

| Abstract: | Based on ANSYS software and industrial rolling of edge drop control,a 3-dimensional finite element model of roll stacks was built for 1 700 mm tandem cold rolling mill.Using this model,the reasons for some problems exists on the 1 700 mm tandem cold rolling mill configuration of the conventional backup roll and tapered work roll system such as the lower shape control,the poor edge drop control effect and the large fluctuation of the edge drop control were analyzed.Based on the FEM analysis and industrial ex... |
