Abstract
The design of the 1 680 m3 blast furnace of Liugang Zhongjin Company adopts many process technology,that is coke and ore bunker and feeding systems apply the process of direct feeding and coke recovery without relay station feeding belt conveyor.The furnace top adopts the PW second-generation standard series tank bell less furnace top and the furnace top uniform pressure release gas recovery process.The crude gas system adopts a five way pipe structure.The furnace body adopts advanced technology such as a thin-walled structure with all cast iron cooling walls and a safety graphite wall in the elephant foot area,WHBJ blast furnace slag treatment process,SDM top combustion hot blast furnace,and ultra clean blast furnace gas dry dust removal process.After being put into production,the main equipment is running well,and various production indicators are steadily improving.
