Dec 14, 2006 · Iron is the primary raw material used to produce steel — itself an alloy of concentrated iron with a minute amount of carbon. Globally, steel production drives 98 per cent of the demand for iron, while electronics and nonmetallurgical uses drive the remaining 2 per cent.
Direct Reduced Iron. The MIDREX MEGAMOD Direct Reduced Iron facility is by far the most advanced plant to produce simultaneous both high quality cold (CDRI) hot direct reduction iron (HDRI). A total annual production of 2,000,000 tons. The plant has the capability for the discharge of hot direct reduction iron (HDRI) from the shaft furnace to ...

Jan 17, 1997 · Abstract: A method and apparatus for the direct reduction of iron in a shaft furnace using gas from the gasifiion of solid fossil fuel, such as coal, in which the fuel gas is desulfurized and upgraded in the shaft furnace and direct reduction of iron oxide is carried out in the same furnace. Clean export fuel can be produced by this method along with direct reduced iron.
The MIDREX process is a shafttype direct reduction process where iron ore pellets, lump iron ore or a combination are reduced in a Vertical Shaft (reduction furnace) to metallic iron by means of a reduction gas (see Figure ) [9].

Midrex has developed a new concept, employing a CO2 removal system that allows for even lower emissions. This option uses an aminetype system that removes CO2 from the top gas. This stream is then preheated, with part of it added to the reformed gas, which goes to the shaft furnace. The remainder is used for top gas fuel in the reformer burners.
