A Direct Reduced Iron (DRI) plant

DRI technology brings significant benefits to steel-making compared to traditional Blast Furnace (BF) techniques:

Lower emissions per tonne of product at 1.1 tCO2 per tonne of steel compared to 2.3 tCO2 for a BF. When combined with an EAF that drops to 0.4 tCO2 per tonne of steel.

Increased flexibility
DRI plants are effective for charging existing BF, BOF and EAF installations
DRI can be stopped and restarted easily and immediately, depending on production requirements.

Improved product quality
Very low residual material (Cu%, Cr%, Ni%) compared to normal scrap
Depending on the iron ore quality, easily chargeable on EAF up to 100% alone or mixed with hot metal from BF.
Carbon content in the product can be easily modulated according to downstream customer requirements.

Good raw material availability
Good quality Magnetite fines and DR pellets are available in many CIS countries.

Direct Iron Reduction Process


Raw material iron ore pellets
Iron ore pellets – the raw material – are fed into the reactor


Natural gas is converted into reducing gas
Natural gas is converted into reducing gas and then injected.
Reducing gas circulates in a closed system and is recycled.

We will use gas as the reducing agent before transitioning to green hydrogen to produce DRI. This approach results in water instead of CO2 emissions.


The direct reduction process
Hot reducing gas flows through the iron ore, from the bottom to the top, according to the counterflow principle.

Oxygen content is reduced and “sponge iron” is produced.


Pressed into briquettes
The “sponge iron” is pressed into Hot Briquetted Iron (HBI).
