Abstract
There is a world wide initiative to extend blast interface in blast furnace hearth furnace campaigns to defer capital expenditures and reduce production costs. Most efforts to rotating disc experiment accomplish this goal at BHP Steel are focussed on the hearth. . The wear of hearth refractory has the greatest influence over the life of the furnace. One aspect of this asset life extension program is the development of a model for computing hearth conditions of typical blast furnace operations. This CFD application is complicated by its wide range of geometric scales (60 mm taphole and 10 m hearth),porous flow, thermal stratification, solidification, and conjugate heat transfer.
