唐钢第二炼铁厂2号高炉(1260m~3)投产于1993年12月10日,炉体采用了全冷却壁的冷却结构和软水密闭循环冷却工艺。高炉用原燃料来自烧结厂、炼焦制气厂和外购土烧球团矿。1996年7月份对2号高炉进行中修处理后,迅速恢复喷吹设施,改进炉料结构,加强技术操作和设备管理,中修后的技术经济指标明显优于1号高炉(1260m~3),并处于国内同级高炉的先进行列。1996年12月份利用系数达到2.04t/(m~3·d),喷煤比达到
The No. 2 blast furnace (1260m ~ 3) of the second ironworks of Tangsteel was put into operation on December 10, 1993. The furnace body adopts the cooling structure with full-cooled wall and the closed-loop cooling process with soft water. The raw materials for blast furnaces come from sinter plants, coking gas plants and purchased burnt pellets. In July 1996 after No.2 blast furnace was repaired, the blasting facility was quickly restored, the charge structure was improved, and the technical operation and equipment management was strengthened. The technical and economic indicators after the remediation were significantly better than that of No. 1 blast furnace (1260m ~ 3) And at the same level in the domestic advanced blast furnace. In December 1996, the utilization factor reached 2.04t / (m ~ 3 · d), and the coal injection ratio reached
