摘　　要：为了找出影响帘线盘条表面缺陷的原因,青钢对此进行了研究,研究发现将对表面质量影响显著的20#～27#轧槽在线时间控制在不大于24h,28#～29#轧槽在线时间控制在不大于4h30min,30#轧槽在线时间控制在不大于4h,16#导卫导轮在线时间控制在不大于12h30min,18#导卫导轮在线时间控制在不大于6h,20#～26#导卫导轮在线时间控制在不大于2h30min,28#～30#导卫导轮在线时间控制在不大于1h,同时定期更换吐丝机前夹送辊入口导管和吐丝管,帘线盘条表面缺陷发生率大幅降低,表面质量得到明显提升,取得了良好的经济效益和社会效益。The causes of surface defects of wire rod for steel cord were studied at Qingdao Steel. It was found that when the online time of the grooves from No. 20 to No. 27 was controlled within 24 hours, that of the grooves from No. 28 to No. 29 controlled within 4 and a half hours, that of the No. 30 groove controlled within 4 hours, that of the No. 16 guide roller controlled within 12 and a half hours, that of the No. 18 guide roller controlled within 6 hours, that of the guide rollers from No. 20 to No. 26 controlled within 2 and a half hours and that of the guide rollers from No. 28 to No. 30 controlled within 1 hour, which influence the surface quality significantly, and the entrance guiding pipe and spinning pipe of the pinching roll before the spinner were replaced regularly, the occurrence rate of surface defects of wire rod for steel cord was greatly reduced and the surface quality obviously improved, achieving good economic and social benefits.
