摘　　要：文章通过对南钢带钢厂工作辊的更换量和更换原因进行调查分析,制定了改进工作辊加工工艺、改进冷却方式等措施,通过措施的实施,有效控制了工作辊的热变形,解决了钢带三点差的问题,提高了轧辊单次过钢量,从而达到降低工作辊换辊量的目标。By investigating and analyzing the work roll change times and reasons in Strip Mill of Nanjing Iron and Steel Co.,Ltd.,this article presents some measures such as improving the working roll machining process and technology and optimizing the cooling mode.After implementation of these measures,the thermal deformation of the work roll is effectively controlled.The problem of three-point difference of steel strip is solved and the rolling capacity of the roll is increased.Thus,the aim of reducing the amount of work roll change is achieved.

关 键 词：工作辊 热变形 钢带三点差 冷却方式 换辊量
