摘要

A model that describes the coupling between the liquid volumes and levels in the blast furnace hearth during operation with different dead man floating states has been developed. Simulation of a simplified, quasi-stationary tap cycle in a one-taphole blast furnace shows the effect of boundary conditions, hearth geometry, coke voidage and dead man floating state on the evolution of the liquid levels and the slag delay. The model has been applied to data from a six-year period of a blast furnace, using the computed inner geometry of the hearth estimated by a hearth wear model, and is demonstrated to accurately predict the long-term variations in the liquid levels. The model is also shown to be useful in tracking the instantaneous liquid levels.
