毕业设计说明书 设计（论文）题目：设计一座年产生铁300万吨的高炉车间 学生姓名： 学 号： 专业班级： 学 部： 指导教师: 摘要 摘要 -I- -I- 摘要 摘要 -I- -I- 按照设计说明书的要求，设计一座年产300万吨的炼钢生铁的炼铁厂。该厂 的高炉车间由2座有效容积2163立方米的高炉，车间布置形式采用半岛式布置。 高炉炼铁生产工艺流程主要包括六个系统：高炉本体系统、高炉车间原料系 统、高炉送风系统、高炉喷煤系统、煤气除尘系统渣鉄处理系统。 其中高炉的炉衬设计方法采用的是均衡炉衬的方法，根据不同的冶炼条件砌 筑不同的砖。冷却方式:炉身部分采用板壁结合的方式炉腰部分采用凸台冷却壁; 炉缸和炉底釆用光面冷却壁和水冷炉底结构。 设计的热风炉采用传统改进型内燃式热风炉。蓄热式和燃烧室在同一炉壳 内。这部分同时包括热风炉各种设备和阀门的选取计算。 上料系统采用的皮带机连续上料，同时增加了皮带的速度和宽度，满足高炉 冶炼的要求。炉顶装料设备采用串罐式无料钟炉顶装料。喷吹系统增加了煤的数 量，釆用了单管路串罐式直接喷吹。煤气处理设备釆用的是湿法除尘设备。 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。 本设计依据现有的经验结合国内外先进生产技术，对设备及相应的参数进行 选择并作了具体阐述和计算，同时对高炉车间工艺布置作了比较详细的叙述，并 绘制里高炉本体砌砖与冷却设备图、热风炉剖面图、高炉车间平面布置图、高炉 车间总剖面图四张图。 关键词：高炉；设计；热风炉；湿法除尘；工艺流程；布置 ABSTRACT ABSTRACT -ii- -ii- ABSTRACT ABSTRACT -ii- -ii- ABSTRACT The designs task is to build an iron-making plant, which has two blast furnaces and each capacity is 2163m3. The plant generates 3000,000 tons iron every year. There are seven chapters in the design. The seven systems of the iron-making plant is follow: blast furnace system raw material systemblast air blowing system fuel injecting systemgas dust removal system slag processing systems The BF lining adopted equalization lining method and was made of alumina brick and chayote in upper of BF and all carbon brick in the bottom of BF.The cooling methods were batten wall style in shaft, boss-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 by heat insulation wall. And the combustion chamber was eye-style. Furthermore this part of the paper included the selection of various equipments and valves. The charging equipment used the belt machine to continuing supplying charge and the belt velocity and width were increased in order to meet the BF melting needs. The furnace roof equipment used string pot style of non-bell furnace roof. Injection system i
