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.
