Abstract：The hearth erosion of Jinan Steel’s No.1 and No.3 1 750 m3 BF have been investigated, although they have the same production conditions and hearth structure. It is found that the No.1 blast furnace hearth pale pot is like the foot-shaped erosion, griddle test shows junction of hearth and bottom are the most serious erosion position, the remaining thickness of the thinnest carbon brick is only 300 mm. The carbon bricks near the iron mouth of the No.3 BF have cracked to some extent, the remaining carbon brick thickness of severe erosion is 600 mm. To improve and prolong the life of the blast furnace, it is suggested that to apply the porous carbon bricks and high reliability thermocouples, reduce the cooling water flow for bottom, increase the cooling water flow of the hearth etc.
