9th International Conference on Modeling and Simulation of Metallurgical Processes in Steelmaking - STEELSIM2021

A blast furnace belongs to the most complex and biggest reactors for the treatment of raw materials. One of the most promising approaches to describe numerically the complex process of a blast furnace is a coupled Euler-Lagrange simulation. It combines an accurate representation of the solid phase with its reducing gas formed by oxidation of coke and iron reduction in conjunction with the...

The lowest part, the hearth, of the blast furnace is the most non-transparent region of the process as no measurements of the internal state are available due to extremely hostile conditions. Since the life of the hearth lining limits the furnace campaign length and the state of the hearth is of significant importance for maintaining an un-disturbed and well-controlled drainage of hot metal...

The burden materials in the blast furnace are traditionally charged to build distinct layers of ore and coke, which makes it possible to control the conditions in the shaft. Since ore and coke have fundamentally different density, the mass flow rates of solids at different radial locations will vary, which affects the heating of the burden upon its descent. Further, as the materials show...
