ABSTRACT:This is a design of blast furnace workshop for output of 1.4million tons
One 1985 m3 blast furnace was used in the desig,no set up Jardine ,two taphole , the use of rectangular field of iron. Blast system 4 Nippon external combustion hot stove, Dust catcher system using gravity precipitators , vebturi tube and electrostatic precipitator .Tapping system method of Wheel law granular slag to deal with special circumstances dry slag production ,the charging system is used in feed belt to ensure uninterrupted blast furnace charge .
In the design, first of all made a material balance, heat balane ,and calculation of furnace design ,as well as the chice of equipment ;the design of the application of a number of advanced technology ,these processes in implementation of large pulverized coal injection technology ,these processes in the implementation of large pulverized coal injection technology to enhance heat transfer efficiency ,energy saving ,to improve productivity played an important role .in the design, the broad absorption of previous technological innovations an the results of scientific research at home an abroad . According to the actual needs and possibilities , as far as possible the use of advanced equipment, advanced structure, advanced materials and so on .Achieve technicaiiy advanced and economically rational, but slso reduce environmental pollution
