摘要: 針對寬帶鋼冷連軋機首次應用的SmartCrown板形控制技術,通過對SmartCrown軋輥大量實測得到了軋輥磨損輥形,采用遺傳算法建立了軋輥磨損預報模型,并利用ANSYS軟件建立了三維輥系有限元分析模型,研究了磨損輥形對SmartCrown板形控制技術在服役過程中板形調控能力的影響,提出了新輥形使用工藝策略．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.
