Abstract:
Sponge Iron production is conducted in various methods that one of them is using coal as a reduction agent. Hoganas process is a different coal-based method that has not been investigated in details. Therefore, the heat transfer method in the system is one of the basic steps to a better recognition of this process (with special Hoganas charging). The present paper investigates the temperature distribution method in the Hoganas cylinder through a numerical model using finite elements. The effects of different parameters, namely preheating and porosity were studied on ceramic crucible made from silicon carbide and it was observed that the consumption energy decreases with the increase of the amount of porosity and preheating temperature. Moreover, the progress of system reactions in the porous media that have significant effects on procedure was concerned in the proposed model. Furthermore, a sample was examined in the particular condition for the evaluation of primary assumptions and the X-ray diffraction analysis results were argued. Finally, the temperature profiles in aforementioned situations were drawn
