The reduction of carbon dioxide gas emission becomes a major concern in the iron and steelmaking industry. Use of hydrogen gas as a reducing agent to replace coke can be considered. The burden profile in the blast furnace is changed because of the decrease of coke usage, thus process efficiency in the blast furnace operation is influenced. Burden distribution models are composed of the falling burden trajectory, a stock and the descent model. A Graphic User Interface (GUI) is added for the convenience of the operators. The mathematical formulas for developing this model were modified by a scaled model experiment and DEM simulation. The entire burden profile obtained by burden distribution model is used to calculate the gas flow pattern in the blast furnace and then used for the calculation of reduction behavior of iron oxides in the blast furnace using multilayer unreacted core model.
