降低高速线材粗轧堆钢的研究

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。

Study of Rough Rolling of the High Speed Wire Rod on Reducing Steel Piled Up

The mechanism of steel piled up of rough rolling was studied in NO .2 factory of high speed wire rod of Jiuquan iron＆amp;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 .
