HOW DOES A DRI PLANT WORK?
DRI technology is used to make iron in electric blast furnaces. To produce high-grade steel, the oxygen must be removed from the iron ore. This is also called reduction. Currently, we do this using coal in our Blast Furnaces. CO2 emissions are a side effect of burning coal. The new DRI technology uses hydrogen instead. This only releases water.
Reduction takes place in a shaft furnace at relatively low temperatures (approx. 1,000°C). After the oxygen has been separated from the iron ore (reduction), it is processed into hot metal in an electric furnace. The hot metal is transported to the BOS Plant by torpedoes over a new railway line. Residual gases area treated in a gas firing installation and CO2 removal plant. This way, we can reuse them in the production process.
