在冷轧带钢厂的焊接、酸洗、退火,镀层和主轧机等机组上,由于设备的加工、安装误差,送料辊的磨损不均和带钢本身的不平整(包括厚度偏差和镰刀弯等),都使带钢偏离机组的中心运行而发生跑偏。当跑偏的带钢边缘与设备接触时,产生阻力,阻碍带钢运行并相互擦伤,从而增加带钢废品率,损坏设备,影响机组正常生产,以致造成停产。为了使带钢不偏离机组中心运行,根据各机组的具体情况,设有校正带钢跑偏的自动控制系统。在机组头部,调节开卷机卷筒的位移量,使开卷出来的带钢在机组中心位置运行;在机组中部,调节送料摆动辊的水平或垂直摆动角度,校正运行中的
In the cold-rolled strip mill welding, pickling, annealing, coating and main rolling mill and other units, due to equipment processing, installation error, uneven feeding roller wear and strip itself (including the thickness of the deviation and sickle bend Etc.), so that the strip deviation from the center of the unit run deviation occurs. When the deviation of the edges of the steel strip comes into contact with the equipment, resistance will be generated, hindering the steel strip from running and scratching each other, thereby increasing the rejection rate of the steel strip, damaging the equipment and affecting the normal production of the unit, resulting in the shutdown. In order to make the strip not deviate from the central operation of the unit, according to the specific circumstances of each unit, with automatic control system to correct deviation of the strip. In the head of the unit, adjust the displacement of the uncoiler roll so that the uncoiled strip runs in the center of the unit; in the middle of the unit, adjust the horizontal or vertical swing angle of the feed swing roll to correct the running
