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.
