摘要
针对薄规格高强钢板形控制困难问题,通过建立有限元模型分析了常规支撑辊+CVC中间辊、CVC补偿支撑辊+CVC中间辊及VCL+支撑辊+HVC中间辊3种代表性辊型配置对高强度冷轧板的板形控制能力的影响。与其他2种辊型配置方案相比,VCL+支撑辊+HVC中间辊辊型配置的承载辊缝的凸度调节域较大、横向刚度较高,辊间接触压力较小。实际生产表明,在该辊型配置方案下,高强度带钢的板形控制精度较高,支撑辊磨损得到有效改善。
To the problem of the shape of high-strength sheet difficult to control, the influences of three repre- sentative forms of roll profile configuration on high-strength strip shape control in CVC cold continuous rolling mill are compared by FEM model, which are conventional back-up roll ＋ CVC intermediate roll, back-up roll with CVC compensation ＋ CVC intermediate roll, VCL＋ back-up roll ＋ HVC intermediate roll. Compared with the other two roll profile configuration, the configuration of VCL＋ back-up roll ＋ HVC intermediate roll increases crown adjustment room and lateral stiffness of loaded roll gap, decreases contact pressure between roils. The production practice shows that the control accuracy of high-strength strip shape and wear of back-up roll are improved by it.
