摘　　要：采用流面条元法分析带材的三维塑性变形 ,影响系数法分析辊系的弹性变形 ,并将二者耦合 ,建立了 4辊轧机板形和板凸度的分析计算模型 ,并针对板宽对 4辊 CVC热带钢轧机板形控制能力的影响进行了仿真研究。仿真结果表明 ,随着板宽的增加 ,出口板凸度先增大后减小 ,辊缝变得越来越平缓 ;单位宽度辊间压力增大 ,且沿横向的变化比较均匀 ;板带的宽展减小。对热带钢轧制 ,乃至厚板轧制具有重要的意义。The three-dimensional plastic deformations of strip are analyzed by the stream surface strip element method, the elastic deformations of rolls are analyzed by the influence coefficient method, the analyzing and computing model of shape and crown is established by combining them, and the influence of strip width on the shape control capability of 4-high CVC hot steel strip mill is simulated and analysed.The simulated results indicate that with the increasing of strip width, the exit crown of strip increases firstly and decreases then, the roll gap becomes smooth increasingly, the unit width contact pressure between work roll and backup roll augments increases and its change along the lateral direction is evener, and the spread of strip reduces.It has an important significance for hot strip rolling, even thick plate rolling.
