Abstract：In order to realize the plan of limiting production for the 3 200 m3 BF in Laiwu Steel, the method of adding a bushing in the tuyere was used to control the wind speed and blast kinetic energy, avoiding drawbacks of blocking local tuyere and changing to small tuyere. Cooperating some measures such as reducing oxygen and ore batch, adjusting burden distribution system and slagging system, strengthening casthouse operation and optimizing tapping organization, the furnace conditions was smooth and the indicators was stable.
