Mathematical Process Modeling :

Due to complexity of the process involved with the blast furnace the process models has been developed on the basis of zonal concept of the Blast Furnace embodying highly complex coupled multiphysics problems namely fluid flow, solid flow, heat and mass transfer, phase change dynamics, combustion and multiphase solid fluid interaction etc.

There are four rigorous models which have been developed for characterizing the blast furnace phenomena

1. Burden Distribution Model

2. Thermo-Chemical Model

3. Raceway Model

4. Freeze-Line Model
