Abstract
In the operation of the ironmaking blast furnace, the function of the hearth is crucial, both to ensure a long campaign and a high production rate of hot metal of high quality. In order be able to take appropriate actions in controlling the state of the furnace hearth, the behavior of it has to be understood. The work reported in this paper has been carried out to study the general behavior of the molten phases in the furnace hearth during tapping. The influence exerted by the state of the hearth coke — the dead man — on the flow patterns has been investigated by CFD modeling. The results of the study agree well with findings reported in the literature as well as with practical observations in the operation of the blast furnace.
