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.

Hearth wearing is the key limit of a blast furnace campaign life. Hot metal flow pattern and temperature distributions are the two key variables to determine the rate and style of the hearth wearing. There are several strategies to control and reduce the hearth erosion, such as changing cooling water temperature and changing the heat transfer coefficient. In this paper, both cooling strategies are investigated using a comprehensive computational fluid dynamics (CFD) code, which was developed specifically for the simulation of blast furnace hearth. That program can predict the liquid flow patterns and temperature distributions of the hot metal as well as temperature profiles in the hearth refractory materials under different conditions. The results predicted by the CFD code were compared with actual industrial operation data. The cooling strategies are evaluated based on the energy analysis and effect on the hearth erosion.

Hearth wearing is the key limit of a blast furnace campaign life. Hot metal flow pattern and temperature distributions are the two key variables to determine the rate and style of the hearth wearing. And the shape, structure and position of the deadman are the three major variables to assign the fluid flow pattern and temperature profile in the hearth. In this paper, a comprehensive computational fluid dynamics (CFD) program which was developed specifically for the simulation of blast furnace hearth was extensively evaluated using actual industrial operation data. That program can predict the liquid flow patterns and temperature distributions of the hot metal as well as temperature profiles in the hearth refractory materials under different conditions. Sensitivity study has also been performed to investigate the effect of the production rate on refractory temperature distribution.
