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 K. 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.
