It is a systematic work to achieve long campaign life of a blast furnace. The present paper introduces experiences from a number of foreign blast furnaces with long campaign life. The paper also introduces the long life blast furnaces in recent 20 years and points out some measures of hearth corrosion delay in operation such as forming solidification layer on hearth side wall, controlling molten iron circulation by improving tapping system and avoiding local erosion by changing the internal structure of the dead man. The paper mentions relevant detailed measures for different hearth corrosion stages as well.
