Abstract：Since Jinan Steel’s 3 200 m3 blast furnace implemented intensified smelting technology, the change of furnace conditions could be divided into two stages: in the first stage, comprehensive grade of the ore into the blast furnace was high; the qualities of the coke and the sinter were good and BF air quantity and the yield are increased. In the second stage, due to constraints of raw materials resource, the coke quality became poor; the Al2O3 content in sinter was higher; the slag ratio was higher and the promotion of the hearth activity was difficult; then the air quantity was low and the yield was decreased. Combined with the actual conditions of smelting furnace condition, the adjustment mentality was put forward, maintaining the stability of the system of blast furnace production and achieving long-term stable operation of blast furnace.
