摘 要 太钢4350m3高炉通过提升原燃料质量管理,采取高富氧率大炉腹煤气量操作下控制合理的煤气流分布、稳定燃料比和加强炉前作业等生产操作管理,使得高炉利用系数得到逐步提高。2008年12月后实现高炉有效容积利用系数2.40 t/(m3.d)以上,炉缸截面积利用系数达66.0 t/(m2.d)以上。
Abstract Since December 2008, TISCO 4350 m3 blast furnace availability ratio is 2.40 t/(m3.d)for continuous and hearth sectional area capacity factor is over 66.0 t/(m2.d)by intensifying crude fuel handling and cast house working as well as high oxygen enrichment high coal injection operation which can realize a reasonable gas current distribution.
