研究了酒钢集团炼轧厂二高线作业区高速线材粗轧堆钢的机理，提出了粗中轧堆钢的解决思路和基本方法，通过系统分析，运用张力控制、钢质控制、钢温控制、料型控制、钢头咬入控制，导卫的改善、岗位工的责任心与技能的提高以及设备点巡检的加强等手段，实现了2013年二高线作业区全年粗轧误轧时间仅214 min，较2012年二高线作业区粗轧误轧时间942 min环比降低了728 min，降幅达77．28％，堆钢次数由22次降至7次，降幅达68．2％，中轧废由21支降至5支，降幅达76．2％，创立了二高线作业区粗轧“零”堆钢的纪录。
研究瞭酒鋼集糰煉軋廠二高線作業區高速線材粗軋堆鋼的機理，提齣瞭粗中軋堆鋼的解決思路和基本方法，通過繫統分析，運用張力控製、鋼質控製、鋼溫控製、料型控製、鋼頭咬入控製，導衛的改善、崗位工的責任心與技能的提高以及設備點巡檢的加彊等手段，實現瞭2013年二高線作業區全年粗軋誤軋時間僅214 min，較2012年二高線作業區粗軋誤軋時間942 min環比降低瞭728 min，降幅達77．28％，堆鋼次數由22次降至7次，降幅達68．2％，中軋廢由21支降至5支，降幅達76．2％，創立瞭二高線作業區粗軋“零”堆鋼的紀錄。

The mechanism of steel piled up of rough rolling was studied in NO .2 factory of high speed wire rod of Jiuquan iron&steel Co .Ltd, the basic ideas and methods were put forword to reduce piled up steel , by analysis of the system , con-trolling steel of tension, adjusting of rolling gap, improving of guide, controlling steel of quality, temperature, sizes, head biting , improving the job responsibility and operation skills and enhancing inspection of rolling equipments , there were on-ly 214 minutes of rough rolling piled up steel which was 676 minutes litter than 942min of 2012 years and was a drop of 77. 28%,number of piled up steel reduced from 22 to 7 with 68.2%and rolled unless steel reduced from 21 to 5with 76.2%in NO.2 high speed wire rod factory in 2013 years, a record of no piled up steel was created in history of rough rolling of NO . 2 high speed wire rod factory .
