河北联合大学轻工学院QINGGONG COLLEGE, HEBEI UNITED UNIVERSITY毕业设计说明书设计题目:设计一座年产 225 万吨炼钢的炼铁车间 学生姓名: 学 号:202515090707 专业班级:09 冶金 7 班 学 部:材料化工部指导老师: 副教授 2025 年 05 月 21 日摘要本次设计是根据唐山地区原燃料条件设计一的座年产 225 万吨的炼钢生铁的炼铁车间。整个车间的平面布置采纳半岛式平面布置形式。设计的高炉有效容积是 1621m3。其中高炉的炉衬设计方法采纳的是均衡炉衬的方法,根据不同的冶炼条件砌筑不同的砖。上部采纳的砖型有高铝砖和黏土砖,下部采纳的是综合炉底砌筑。冷却方式:炉身部位采纳板壁结合的方式炉腰部位用镶砖冷却壁;炉缸和炉底采纳光面冷却壁和水冷炉底结构。设计的热风炉采纳传统内燃式热风炉。蓄热室和燃烧室在同一炉壳内,中间用隔热墙隔开;采纳矩形陶瓷燃烧器。这部分同时包括热风炉各种设备和阀门的选取计算。上料系统采纳的是皮带机连续上料,同时增加了皮带的宽度和速度,满足高炉冶炼的要求。炉顶装料设备采纳并罐式无料钟炉顶装料。喷吹系统增加了煤的数量,采纳了单管路并罐式直接喷吹。煤气处理采纳的是干法除尘设备。所涉及的计算有高炉和热风炉尺寸的计算、高炉的物料平衡和热平衡计算以及热风炉风机的选择等。关键词:高炉;热风炉;干法除尘;无钟炉顶;风机AbstractA blast furnace plant of 2.25 milliong tons product annual was designed in the paper according to Tanggang’s original fuel condition . The horizontal layout of the whole plant is peninsula type layout.The dischargeable capacity of the BF in this design is 1621 m3. among it ,the BF lining adopted equalization liniing method and was made of alunina brick and clay brick in upper of BF and comprehensive bottom furnace structure. The cooling methods were batten wall style in shaft, brick wall with cooling stave in bosh, smooth cooling stave in hearth and water-cooling stave in bottom of hearth.The air-stove was modified tradition style of internal combustion. The checker chamber and combustion chamber were in the same furnace shell and divided...
