摘 要:高炉炼铁是获得生铁的主要手段，也是钢铁冶金过程中最重要的环节之一，在国民经济建设中起着举足轻重的作用。本着优质、高产、低耗和对环境污染小的方针，设计建造年产量为180万吨的炼铁车间。车间共有2074.93m3高炉一座，高炉采用了全冷却壁、砖壁合一薄壁炉衬、铜冷却壁、炭砖—陶瓷杯复合炉底、全软水密闭循环冷却系统、PW串罐无料钟炉顶、内燃燃式热风炉、全干式布袋除尘等一系列先进实用技术。
设计的主要内容包括炼铁工艺计算（包括配料计算、物料平衡和热平衡）、高炉炉型设计、高炉各部位炉衬的选择、炉体冷却设备的选择、风口及出铁场的设计、原料系统、送风系统、炉顶设备、煤气处理系统、渣铁处理系统、高炉喷吹系统和炼铁车间的布置等。

ABSTRACT:Pig iron is main from blast furnace，furnace ironmaking is also a important process in iron and steel making，and it is play an important role in the construction of national economy. based on the target of high productivity, high quality, lowconsump tion, long campaign and environment protection.the design is aim at design a furnace which produce 1800 thousands pig iron per year，the plant has a 2074.93m³ furnace which series of advanced and applicable technologies were adopted, such as full cooling stave, thin inner lining of integrated bricking and staves, carbonbrickscombined furnace bottom with ceramic cup, closed loop soft water circulation and cooling system, bell - less top with central charging hopper, inner combustion burner type hot air stove, dry bag gas dedusting etc.
The design program consist of abstract、foreword、technological calculate（contain blast-furnace burden、material balance calculate and thermal equilibrium calculate），the choose of furnace lining and cooling plant，the design of furnace lines，tuyere and casting house，material system，blast system furnace roof system，gas dispose system，iron and slag dispose system，fuel injection system and the disposition of plant.Besides，the design also consult some advanced produce experience and data from home and abroad similar furnace to make the design achieve best.
