摘　　要：针对国内某4200mm中厚板轧机首次采用SmartCrown板形控制新技术,采用ANSYS9.0建立了辊系三维有限元模型,通过有限元仿真分析发现在SmartCrown工作辊和常规凸度支持辊的辊型配置下,采用SmartCrown的轴向移位变凸度技术,中厚板轧机的板形控制能力大大增强,但是辊间接触压力的不均匀性和接触压力峰值明显增大。在结合VCR支持辊优势的基础上,提出了4200mm中厚板轧机SmartCrown工作辊相匹配的辊形SVR(SmartCrown-VCR Compounded Roll)。对比分析发现采用SVR支持辊后可以明显减小辊间压力尖峰、均化辊间压力分布和提高轧机对板形调控能力。The new SmartCrown profile and flatness control technology is first adopted in plate rolling mill.On the basis of data collected from the 4200mm plate mill,the 3-D finite element roll system model was built by the ANSYS finite element software.Because of the axial shifting variable crown technology of SmartCrown,the plate rolling mill has better ability of strip shape control,but poor roll contact state between work and backup rolls if using the roll configuration of SmartCrown work roll and conventional crown backup roll. On basis of VCR backup roll,a new backup roll contour-SVR （SmartCrown-VCR Compounded Roll） is proposed. If adopting the roll configuration of SmartCrown work roll and SVR backup roll,it has the advantages of the small roll pressure peak,the contact pressure uniform and the better ability of shape control.
