摘　　要：分析了1 800 mm炉卷轧机出现的带钢表面异物压入缺陷的特征、分布规律及产生的原因。通过炉衬材料革新改造、优化卷轧工艺、优化卷取炉升降温曲线、导卫灰清理改进及增设吹扫装置等措施的实施,带钢表面异物压入缺陷率由0.7%降到0.2%以内,提高了产品质量。The characteristics, distribution and causes of the rolling indefects on the surface of the strip surface of the 1 800 mm SMwere analyzed. Through the renovation of the lining material, the optimization of roll forming process, the optimization of the temperature rise and fall curve of the coiler furnace, the cleaning of the guide and the improvement of the blowing device, the rate of rolling in defect on the surface of strip was reduced from 0.7% to less than 0.2%, the quality of products was improved.
