Abstract：In the paper, a series of new process and technology adopted in newly built No.3 3 200 m3 BF in laiwu steel are introduced, such as comprehensive technology of blast furnace longevity,multi nozzle type and fixed hopper of PW bell-less top, technology of axial cyclone deduster plus automatically discharging ash system, environmental INBA slag granulation technology, the dehumidified blast technology of BF and so on. The blast furnace was started up smoothly and reached the design product, in addition, all kinds of operation experience was happened, for example, intensified smelting, high coal ratio, large ore batch, limited production, wind-off without plan. The results were verified that every system ran normally and had better technical and economic index.
