In this test we have two 2520 m3 blast furnaces and set up two tap holes with no slag hole, which use rectangular field of iron. Air supply system have 4 combustion .Dust catcher system uses gravity precipitators and venturi tube to handle. Slag iron processing system use water quenching residue Lhasa (RASA), special circumstances use dry slag productions to deal .The charging system use belt feeding machine to ensure the blast furnace charge. In the design first of all we make a material balance，heat balance and calculation of furnace design,as well as the choice of equipment; the design of the application of a number of advanced technology equipments ,these processes in the implementation of large pulverized coal injection technology to enhance heat transfer efficiency, save energy, improve productivity which played an important role in design.According to the actual need and possibilities we use advanced equipment as far as possible structure, materials and so on. Achieve technically advanced and economically rational and reduce environmental pollution. The type of workshop with the overall lay
