简介：南钢4号1800m~3高炉于2014年1月24日点火开炉,高炉投产后顺利达产达效,随着高炉冶炼强度的提高,2016年上半年,铁口区域冒煤气严重,铁口难以维护,同时大量的煤气外泄严重威胁炉前工的人身安全。2016年10月17日计划检修,采取铁口框架内整体浇注技术、铁口及风口区域压浆技术、加强炉外管理和炉内管理、提高炮泥质量等措施,治理效果显著,煤气火逐渐减小。

简介：随着南钢高效率生产低成本智造精品钢理念的确立,提高利用系数已经成为4号高炉操作者亟待解决的首要问题。从2017年1月起,4号高炉在稳定炉况的基础上充分挖掘高炉产能,进行提高高炉利用系数的生产实践。高炉利用系数由2016年平均2.49t/m~3·d提高到2.90t/m~3·d左右。
