What is Direct-reduced Iron (DRI) Definition from
Aug 29 2014 · Direct-reduced iron (DRI) is a type of metal substance produced from heating elemental iron in the presence of gas generated from natural gas or coal burning. Due to the low degree of oxygen present DRI is prone to oxidation and has a higher corrosion rate compared to other types of iron.

DRITAKFA
Direct Reduction is a metallurgical process of producing sponge iron from iron oxides (mainly from lump iron ores or pellets) directly in the solid phase. The product of this solid state route has a honeycomb structure with minute pores. Hence this product is most commonly known as sponge iron/direct reduced iron (DRI).
