Influence of Different Porosity of Dead-Man to Flow of Hot Metal in the Hearth of Blast Furnace

Abstract:

Circuiting flow of hot metal is one of reasons for erosion in hearth, which is brought mainly by dead-man in hearth. Studies the influence of different porosity of dead-man to flow of hot metal in the hearth of blast furnace .The results show that:When the porosity of dead-man is reduced,the hot metal on the bottom and the wall of furnace erosion increase.
