Optimization of Shape Control Capability of 1750 mm Hot Roll-ing Line
This paper analyzes the basic characteristics of the original roll shape configuration scheme of the finishing mill of Bayi Steel's 1750 mm hot rolling production line,and evaluates the grinding accuracy of the roll of the roughing mill.The re-search found that the control ability of positive crown of the upstream stand in the original roll shape configuration scheme of the 1750 mm hot rolling line finishing mill of Bayi Iron and Steel Co.,Ltd.was weak,and the control ability of negative crown was excessive,resulting in the disharmony of the control ability of the upstream and downstream stand crown,while the grind-ing degree of the rough mill roll was large,and the roll accuracy was low.Therefore,SmartCrown roll shape is used to optimize the crown control range of the finishing mill stand,and the scientific and reasonable control scheme is used to control the roll operation process and management process,roll grinder working accuracy,roll change cycle and processing accuracy,which significantly improves the shape control ability and production stability of the hot rolling production line.
