Abstract
A two dimensional mathematical model is developed describing four phase motion and heat transfer in the blast furnace. The four phases are gas, lump solid, liquid and powder. The model includes simple representations of the major chemical reactions and physical structures within the furnace. It calculates the steady state velocity, temperature and volume fractions of all four phases. The model is able to allow for the influence of the behaviour of each phase on that of every other phase. In particular, it can predict how the behaviour of one phase may change in response to a modification to another phase's behaviour.
