先进变凸度工作辊辊形及其控制特性
Advanced variable crown work roll contour and its crown control characteristics
摘要
Abstract
After industrially tracing and testing the shifting positions of continuously variable crown（CVC） work rolls for a 2 250 mm hot strip production line,it was found that CVC work rolls always worked at the limit positions.The analysis showed that the quadratic crown control capability of the CVC work roll contour declined quadratically with decreasing strip width,leading to an insufficient crown control capability to narrow strip steel,and so did SmartCrown work rolls.A new advanced variable crown（AVC） work roll was proposed,whose quadratic crown and quartic crown vary linearly with roll shifting positions.With the quartic crown control capability increasing,the quadratic crown control capability varies slowly with strip width,indicating that the new contour can improve the crown control capability of a wide strip or super wide strip rolling mill for different strip widths.关键词
