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 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 In addition, the Corex process can use iron oxides containing up to 80% lump ore and uses non coking coal directly as a reducing agent The COREX process offers high smelting intensity and hence higher productivity, ability to use various types of noncoking coals, use of iron ore fines to an extent, low net operating cost, possible generation of power or other alternative use of export gas generated from (PDF) COREX PROCESS in IRONMAKING Elvis Marca Catachura Feb 22, 2017 The most innovative feature of the Corex process is the separation of the iron reduction and smelting operations into two separate reactors, namely reduction shaft and meltergasifier In the twostage operation of the process DRI produced from a shaft furnace is charged into a meltergasifier Corex Process for Production of Iron – IspatGuru

Dec 02, 2009 The COREX process offers high smelting intensity and hence higher productivity, ability to use various types of noncoking coals, use of iron ore fines to an extent, low net operating cost, possible generation of power or other alternative use of export gas generated from the ironmaking unit, besides being ecofriendlyIn a nutshell, COREX is a coal based SR (smelting reduction) process of making hot metal or pig iron by direct use of noncoking coal The outputs can be used either by integrated mills or EAF (electric arc furnace) mills The process gasifies noncoking coal in a smelting reactor, which also produces liquid ironCOREX Process of Iron Making its Merits and Demerits Corex enables the costefficient and environmentally friendly production of hot metal from iron ore and coal In the Corex process, all metallurgical work is carried out in two separate process reactors – the reduction shaft and the melter gasifierCOREX® — SMELTING REDUCTION PROCESS
Corex Process Industrial Efficiency Technology Measures
Corex Process Corex is a smelting reduction process combining a melter gasifier with a reduction shaft The process takes lump iron ore or pellets, noncoking coal, and oxygen as main inputs Similar to the blast furnace process, the reduction gas moves in counter flow to the descending burden in the reduction Corex is a smelting reduction process: Coal gasification, iron ore reduction, and liquefaction of the resulting iron are combined in one process The gases produced can immediately be used for heating or for generating electricity in a gas and steam turbine power plantCleaner Iron Production with Corex ProcessCorex is a smeltingreduction process developed by VAI, for costefficient 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 unitsJSW CorexGreen Technology to produce hot metal
