首钢京唐钢厂“一罐到底”模式运行实践分析

“One Ladle Technology” operation practice analysis in Shougang Jingtang

＂一罐到底＂模式是目前铁钢区段中较为先进的运行模式,与其他模式相比,在占地面积、设备投资、人员配备、运行时间、铁水温降、粉尘排放等方面具有显著优势,已经被钢铁企业接受并逐渐应用。对首钢京唐钢厂高炉-转炉区段＂一罐到底＂运行模式进行了系统研究,重点对首钢京唐钢厂铁钢区段的运行时间和铁水罐周转时间进行解析,并对铁水罐重罐和空罐的温降进行解析。在此基础上,提出铁水罐周转过程动态运行规则,并在首钢京唐钢厂取得了显著效果。

＂One Ladle Technology＂mode is more advanced operation mode in BF-BOF section. OLT,which has a significant advantage in area occupying,equipment investment,staffing and operation time,temperature drop of hot metal and dust emission compared with other models,has been gradually accepted and applied in steel production enterprises.Based on the case study of BF and BOF section＂One Ladle Technology＂in Shougang Jingtang,operation mode in time and HML turnover time,temperature drop of full HML and empty HML are analyzed. Based on the results,the dynamic operating rules for HML turnover are put forward which has achieved remarkable results in Shougang Jingtang.
