iron ore grade wise proportionate use in direct reduced plant

Direct reduction(DR) is defined as any process in which metallicironis produced by thereductionofiron oreat temperatures below theiron melting point. The product of a DR process is calleddirect reduced iron(DRI). The major consumers ofDRIare the smaller steel mills whichuse DRIto dilute theresidualelements present in the steel scrap.

Althoughiron ore concentratesare generally higher iniron gradeand contain lower impurities, the finer size distribution of concentrates limits theirusageiniron ore sintering. Therefore, pelletizing is needed to produce fired pellets from concentrates as burden materials for blast furnaces anddirect reduction processes.

Useofdirect reduced iron(DRI) as a partial replacement to scrap, to some extent does help in overcoming this hurdle. However, unlike scrap and evenpig iron,DRIis characterized by highporosity, low thermal and electrical conductivities which, in turn, poses problems in its melting.

Iron oreis a mineral substance which, when heated in the presence of a reductant, will yield metalliciron(Fe). It almost always consists ofironoxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3).Iron oreis the source of primaryironfor the world'sironand steel industries.

Until the 1950s of the last century, the oxidizedironores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron oresources has made necessary the utilization of concentration processes with the purpose of enriching theiron ore. Because of these processes, a fine granulometry is produced, and thusironagglomeration ...
