Midrex Process for Direct Reduction of Iron Ore – IspatGuru

These days standard Midrex shaft furnace has the features like (i) thin wall refractories at the reduction zone of the furnace to reduce the pressure drop of the burden and to increase the furnace volume, (ii) a double bustle port for injection of reducing gas since this allows the gas to better penetrate into the centre of the burden in the reduction zone and thus improves the metallization ...

furnace, basic oxygen route [2]. Among DR processes, shaft furnaces represent over 82% of the world's DR iron production, with the two main processes being MIDREX (65%), as shown in Figure1, and HYLENERGIRON (17%) [3]. In a DR shaft furnace, a charge of pelletized or lump iron ore is loaded into the top of the furnace

Modeling and Simulation of the MIDREX Shaft Furnace ...

Metallic iron used in steel industries is mostly obtained from a direct reduction process. The focus of this study is to simulate the furnace of the MIDREX technology. MIDREX technology which is the most important gasbased direct reduced iron (DRI) process in the world, includes reduction, transition and cooling zones. The reduction zone considered as a counter current gassolid reactor ...
