攀钢冷轧厂重卷机组活套辊印分析

Looper Analysis of Panzhihua Iron and Steel Cold Rolling Mill Roll Printing Recoiler

攀钢冷轧厂新投建了一条重卷机组,带钢在机组的活套处产生了明显的辊印缺陷,该缺陷在带钢上下表面都有,集中于带钢的操作侧及中部。其产生原因是辊子加工过程中产生的点状局部凸起,以及辊子安装不水平。通过对辊子的安装位置调整,及辊面进行打磨处理,有效地控制了辊印的产生。

PG cold rolling plant built a new recoiler unit, the strip had a significant flaw in the looper roll printing unit at the top and bottom surfaces have defects in the strip, focusing on the operating side and the middle of the strip. Its cause is dotted roller process raised locally produced, as well as the level of the rollers is not installed. Through the installation position adjustment of the roller, the roller surface grinding and processing, effectively control the roll printing production.
