摘要: 针对宽带钢冷连轧机首次应用的SmartCrown板形控制技术,通过对SmartCrown轧辊大量实测得到了轧辊磨损辊形,采用遗传算法建立了轧辊磨损预报模型,并利用ANSYS软件建立了三维辊系有限元分析模型,研究了磨损辊形对SmartCrown板形控制技术在服役过程中板形调控能力的影响,提出了新辊形使用工艺策略．

Abstract: In order to master the SmartCrown system for profile and flatness control first applied on a 1700mm tandem cold roiling mill, the SmartCrown work roll wear pattern was obtained on the basis of large amount of measured roll contours. A prediction wear model of the SmartCrown work roils was built up by using genetic algorithm. The effect of the roll wear contour pattern on profile and flatness performance was analyzed by the developed three-dimensional finite element analysis model of a roll stacks system with ANSYS software. A new rolling strategy was brought forward for application of the new SmartCrown system.
