The scrap vanished gradually causing threat to the Arc furnace where BF-BOF process continued its predominance as age-old process in the world. During 70's, the reduction of iron ore in small way was carried out in China in the same manner as retile was produced from illuminate and birth of DRI / Sponge Iron was brought into existence.

The overall reduction reactions in a DRI shaft furnace are: Fe 2 O 3 (s) + 3H 2 (g) → 4Fe (s) + 3H 2 O (g) Fe 2 O 3 (s) + 3CO (g) → 4Fe (s) + 3CO 2 (g) Water vapor and carbon dioxide are byproducts of the DRI process. DRI can be very attractive in regions or countries lacking coal reserves, but with plentiful iron ore and natural gas ...

The HBIS DRI plant will use make-up gas with approximately a 70% Hydrogen concentration.Due to the high amount of H 2, the HBIS plant will be the greenest DRI plant in the world by producing only 250kg of CO 2 per ton of DRI. The carbon dioxide will be selectively recovered and part of it will be reutilized in downstream processes, with a final net emission of just about 125kg of CO 2 per ton.

Instead of sinter, the DRI process uses pelletised iron ore. But just like sinter, it still has to have the oxygen removed. This process is known as 'reducing'. Instead of coke, the energy source used in the DRI furnace is natural gas. Again, the result is liquid iron. From the DRI furnace, the iron moves to the electric arc furnace on conveyors.

Direct Reduced Iron (DRI)
DRI: Iron produced by reducing an iron ore (65-70% iron) by reducing gas (H2+CO) at a temperature (approx. 800-1050 °C) high enough to burn off its carbon and oxygen content.
Reduction is done below the m.pt of iron cause the produced iron may react with water and air under the evolution of heat.

The process description. 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 melter-gasifier. In the two-stage operation of the process DRI produced from a shaft furnace is charged into a melter-gasifier for smelting.

The chemical energy generated from the excess C DRI reduces the kWh/Te, power-on time, and tap-to-tap, and thus increases productivity. The CO generated from the combustion foams the slag creating a foamy slag, increasing the slag's surface area, improving removal of undesirable elements from the steel (including N, H, S, and P), and 'refining' it.

DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800-1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines.
