The Mathematical Model of Iron Blast Furnace :
The iron blast furnace is a giant and tremendously expensive
furnace to produce hot metal from iron ore. Mathematical model-based prediction
and control of its inner circumstances are very important not only for
its stable operation but also for remarkable reduction of energy consumption
as well as carbon dioxide to be emitted from the furnace. The targets of
the model involve non-uniform flows of gas, solid, liquid and powders,
complicated heterogeneous reactions, and profiles of concentration and
temperature which widely ranges from the room temperature to a high temperature
up to 2500 ºC. Some mathematical models so far developed by us are
being processed on on-line computers of steel industries. More sophisticated
functions are being developed and implemented to the models.
