摘　　要：圆盘剪是冷轧板带生产中的关键设备之一,主要用于对板带的定尺裁边。文章以包钢稀土钢板材公司冷轧酸轧机组圆盘剪为研究对象,对冷轧板带切边作业的设备结构和原理进行分析,对圆盘剪剪刃使用及标定、工艺参数调整与切边质量的关系进行分析和改进,提高了圆盘剪工作的稳定性,降低了切边缺陷发生的概率,有效地改善了成品带钢的切边质量。The circle shear is one of the key equipment in production of cold rolling strip,which is mainly used for cutting to length and trimming of strip.In the paper,the structure and principle of equipment for trimming operation of cold rolling strip is analyzed as well as the relation among use and calibration of shear edge for circle shear,process parameter adjustment and quality of trimming is analyzed and improved by taking the circle shear of cold-rolled steel pickling crew in Inner Mongolia Baotou Steel Rare Earth Steel Plate Co.,Ltd.as research object so that the stability of circle shear is improved,probability of trimming defect is reduced and quality of trimming for finished strip steel is improved effectively.
