In a nutshell, COREX is a coal based SR (smelting reduction) process of making hot metal or pig iron by direct use of non-coking coal. The outputs can be used either by integrated mills or EAF (electric arc furnace) mills. The process gasifies non-coking coal in a smelting reactor, which also produces liquid iron.

coke (also used as energy input to the process) or alternative reducing agents, limestone and dolomite. Steel production requires iron, steel scrap and lime (burnt limestone). The iron ore is smelted to produce an impure metal called "hot metal" when in liquid phase or "pig iron" when in solid phase.

HIsarna ironmaking process - Wikipedia

The HIsarna ironmaking process is a direct reduced iron process for iron making in which iron ore is processed almost directly into liquid iron or hot metal.The process combines two process units, the Cyclone Converter Furnace (CCF) for ore melting and pre-reduction and a Smelting Reduction Vessel (SRV) where the final reduction stage to liquid iron takes place.

Dec 14, 2018  The types of reinforced steel bar grades are Fe 415, Fe 500, Fe 550, Fe 600. The manufacture of steel begins with the steel making process, in which pig iron is purified and alloyed to make ingots. One major part in steelmaking is the ironmaking process which is the production of iron

Direct-Reduced Iron - an overview ScienceDirect Topics

SR involves combining iron ore reduction with melting in a reactor, without the use of coke. The product is liquid pig iron, which can be treated and refined in the same way as hot metal from the BF. So far, only the COREX® process has been commercially proved, but a number of other variants are in an advanced stage of development.

USGS Minerals Infromation: Statistical Compendium - IRON ORE

By Peter Kuck Iron is the fourth most abundant rock-forming element and composes about 5% of the Earth's crust. Astrophysical and seismic evidence indicate that iron is even more abundant in the interior of the Earth and has apparently combined with nickel to make up the bulk of the planet's core.
