冷轧厂横切机组飞剪抖动原因分析及处理方法

Cause analysis and treatments of eccentric shear in the cross cut unit of the cold rolling mill

介绍了武钢冷轧横切机组在生产过程中存在的飞剪抖动问题及对生产造成的严重影响,分析了飞剪的工作原理及控制方式,探讨出造成飞剪抖动的原因。并结合本机组的实际生产情况,给出了解决该问题的方案,成功解决了飞剪抖动的问题,既提高了板材成材率,又在很大程度上降低了设备故障时间。

Firstly, this paper presents the background that eccentric shear exist the sha- king phenomenon in the process of production at cross cut line of Cold Rolling Mill of WISCO, and points out that the shaking of eccentric shear caused serious influence on production. Then, this article analysis the working principle and control mode of eccen- tric shear. Basing on this , we discusses the cause of the shaking phenomenon. Combi- ning with the practical condition of the unit, this paper gives the solution of this problem through using a appropriate and feasible treatment method. It confirms that this so- lution eliminates the shaking phenomenon successfully. Not only improve the plate yield rate, but also largely reduce the equipment fault time.
