Iron Production Corex Process In India

Corex Process - Wikipedia

The Corex Process is a smelting reduction process created by Siemens VAI as a more environmentally friendly alternative to the blast furnace. Presently, the majority of steel production is through the blast furnace which has to rely on ever decreasing amounts of coking coal. That is coal which has been cooked in order to remove impurities so that it is superior to coal. In addition, the Blast furnace requires a sinter planttoo in order to prepare the iron ore for reduction. Unlike the Blast Furnace, smelting reduction proc

Corex Process for Production of Iron – IspatGuru

Corex process distinguishes itself from the blast furnace route by (i) direct use of non-coking coal as reducing agent and energy source, (ii) Iron ore can be directly and feasibly charged to the process in form of lump ore, and pellets, and (iii) use of pure oxygen instead of nitrogen rich hot blast. Direct use of non-coking coal is possible since the coal is charred inside the melter ...

COREX® — SMELTING REDUCTION PROCESS

Corex enables the cost-efficient 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 gasifier. Since coking and sintering plants are not required for the Corex process, substantial cost savings of up to 20% can be achieved in the ...
