摘要: 針對冷連軋機帶鋼邊降板形控制問題,研究了單錐度工作輥的輥形構成、特點和控制策略,建立有限元模型對比分析了單錐度、常規凸度和SmartCrown工作輥板形控制性能,并結合大型工業軋機調試實驗分析了該板形控制新技術在實際生產中的使用情況.結果表明,應用單錐度輥可以有效降低帶鋼邊降,減小帶鋼總凸度.Abstract: The construction, characteristic and shift strategy of a taper work roll were investigated for the problem of edge drop control during continuous cold rolling. A finite element model was built to analyze the strip shape control capability of the taper work roll, common crown work roll and SmartCrown work roll contrastively, and the application of this new strip shape control technology to real production was discussed based on the debugging tests on a large production mill. The results show that the use of a taper roll can reduce the edge drop and total crown of strip steel efficiently.
