This paper introduces the top system design situation of 1780m^(3) blast furnace engineering of relocation project of a steel company in Tangshan, and expounds the main technical features, process equipment,and using effect after putting into production of the top system of this blast furnace. A large number of innovative technologies and advanced equipment have been adopted in the design of the top system of this blast furnace: The furnace top system has adopted PW’s standard tandem bell less top equipment with advanced technology and good performance;the furnace top pressure equalizing and pressure discharging system has adopted the innovative furnace top pressure equalizing gas full recovery technology, which can save a lot of blast furnace gas and reduce the pollution caused by gas emission to the environment;the auxiliary system matched with furnace top equipment has adopted mature, practical and reliable technology and equipment. The application of the above advanced technologies and equipment has created conditions for the high efficiency, low consumption, long life and stable production of the blast furnace.
