2230冷连轧机带头飞翘原因分析与措施

Cause analysis and measures for warped head of strip in 2230 cold tandem mill

2 230mm西马克冷连轧机在生产过程中因轧机出口带头飞翘问题频繁停车,产线多次停车导致机组作业率下降,废品量明显上升。通过现场观察以及生产数据分析,调整了轧机出口的剪切张力,优化了剪切时序,规范了穿带速度,增加了变厚度轧制功能,机械人员在皮带助卷器加装磁铁。通过一系列措施,成功解决了厚带钢带头飞翘问题,实现了稳定剪切穿带,显著降低了机组停机时间,减少了废品量。

2230 mm SMS cold rolling mill was frequently stopped in the production process due to the warped head of the strip.The multiple stops in the production line led to the decline in unit running rate and the obvious increase of the waste coil.Through the site observation and production data analysis,the shear stress of the mill outlet was adjusted,the shear timing was optimized,the cut speed was standardized,the variable thickness rolling function was increased,and the magnet was installed on the belt wrapper by the mechanical personnel.Through a series of measures,the problem of the warped head of the thick strip was solved successfully,and the stability of shear belt was realized,and the unit downtime,as well as the quantity of waste product,was significantly decreased.
