高强钢冷连轧机辊形配置对板形控制性能的影响1 1 2 2 吴 彬 张清东 张晓峰 （1.宝山钢铁公司（集团），上海 201900 ； 2. 北京科技大学机械工程学院，北京 100083 ） 摘 要 针对高强度带钢的特点，分析了 CVC 冷连轧机辊形配置及其变化，建立有限元模型分析了常规支持辊配 合 CVC 中间辊、CVC 补偿支持辊配合 CVC 中间辊、VCL+支持辊配合 HVC 中间辊等三种代表性 CVC 冷连轧机 辊形配置对高强度冷轧板的板形控制性能的影响。与常规支持辊配合 CVC 中间辊的辊形配置相比，VCL+支持辊配 合 HVC 中间辊辊形配置的承载辊缝凸度调节域提高了 26.74%，辊缝横向刚度提高了 22.09%，辊间接触压力峰值 下降了 27.43% 。新的辊形配置在宝钢 1730mm 冷连轧机得到工业应用，生产数据表明，高强度带钢的板形控制精 度得到提高，支持辊磨损得到改善，取得显著的应用效果。 关键词 冷轧 辊形 有限元 板形控制 Effect of Roll System Arrangement of Tandem Cold Mill for Advanced High Strength Steel on Shape Control Performance Wu Bin1 Zhang Qingdong2 Zhang Xiaofeng2 (1.Baoshan Iron Steel Co.,Ltd.,Shanghai, 201900；2.School of Mechanical Engineering, University of Science and Technology Beijing, Beijing，100083) Abstract This paper analyzes the roll system arrangement of CVC tandem cold mill and its changes. This paper analyzes three ways including conventional backup roll with CVC intermediate roll,CVC compensatory backup roll with CVC intermediate roll and VCL+ backup roll with HVC intermediate roll and their effects on shape control performance of tandem cold mill for advanced high strength steel through finite element model. Compared with the roll system arrangement including conventional backup roll and CVC intermediate roll, the roll system arrangement including VCL+ backup roll and HVC intermediate roll can improve adjustable area of 26.74%,transversal stiffness of loaded roll gap of 22.09% and it can also reduce the contact force between rollers of 27.43%.The new roll system arrangement is used in 1730mm tandem cold mill of Baoshan Iron.
