Corex Process - WikiMili, The Best Wikipedia Reader

Corex Process Last updated April 26, 2020. 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.

Comparative analysis of energy requirements of CO2 …

The Corex process of obtaining pig iron is a modern technology, considered more friendly for the natural environment than blast-furnace, because non-coking coal is used as a source of energy and reducing agents. In this way the harmful effects of cokeries are eliminated.

MIDREX Processes -

The process reduces iron ore using a reforming gas made from natural gas. The DRI is used mainly as the raw material for electric arc furnaces (EAFs), as a clean iron source substitute for scrap iron. Pores are left behind in the DRI after oxygen has been removed. These pores, if filled with water, for example, can cause the iron to reoxidize with
