COREX Process of Iron Making - its Merits and Demerits

Compared with the traditional iron making process via the blast furnace route the COREX process differs since non coking coal can be directly used for ore reduction and melting work eliminating the need for coking plants. The use of lump ore or pellets also dispenses with the need for sinter plants.

ii Absence of post combustion means that much chemical energy is lost in the exit gases and consequently the coal consumption in Corex is much higher than in any other iron making process. iii The system is maintenance oriented including cooling gas compressor for recycling part of COREX gas for cooling the hot gases from the melter-gasifier.

Corex Process - Wikipedia

The Corex process consists of two main parts a Reduction Shaft and a Melter- Gasifier. The main reagents for the Corex process are iron ore noncoking coal and oxygen . 5 Unlike the Blast furnace the Corex process does not use a hot blast of nitrogen thereby greatly reducing NOx gas emissions but instead uses oxygen.

JSW - Corex-Green Technology to produce hot metal

Corex is a smelting-reduction process developed by VAI for cost-efficient and environmentally friendly production of hot metal from iron ore and low grade coal. The process differs from the conventional blast furnace route in that low grade coal can be directly used for ore reduction and melting work eliminating the need for coke making units.

COREX — SMELTING REDUCTION PROCESS

Economical iron making basis for a new steelworks in an isolated area with limited access to fuel gas. Our solution Corex-DR combination consisting of two Corex C-2000 plants with a total annual output of 1.6 million tons of hot metal and a MIDREXTM DR plant with an annual output of 1.2 million tons of DRI.

Corex Process for Production of Iron – IspatGuru

The attractiveness of the Corex process is due to i hot metal quality suitable for steelmaking ii low investment and operational costs due to the elimination of coke ovens and by product plant iii low process related emission rates iv use of a wide variety of iron ores and especially non-coking coals and v generation of a highly
