Process Design of No.3 Blast Furnace Stack in Qian'an Steel

对迁钢3号高炉炉体工艺设计进行了总结。其主要特点是:结合迁钢自身的原燃料条件,确定了较为合理的炉型;以优质耐火材料为基础的"炭质炉缸-综合炉底"结构;软水密闭循环冷却系统与工业水系统相结合;在炉缸局部、炉腹、炉腰及炉身下部关键区域采用铜冷却壁;完善的检测临控系统等。

It is introduced in the paper the process design of No. 3 blast furnace stack in Qian＇an SteeL. A rational furnace profile is selected considering the condition of raw materials used, together with other advanced technologies, such as ＂ car- bon brick furnace hearth ＋ comprehensive furnace bottom＂ lined with high quality refractory, closed loop soft water recircula- tion cooling system ＋ indust~ water system, copper cooling staves at furnace hearth, bosh, belly and the critical lower part of furnace stack, and excellent measurement and monitoring system, etc.
