HBI production | International Iron Metallics Association

All effective methods of direct reduction actually use the same process: rich iron ore (fine concentrate or pellets) is reduced by a special gas mixture up to the iron content of 85-90%. This explains why the production of direct-reduced iron is mainly concentrated in countries with large reserves of oil (oilwell gas), natural gas and iron ore ...

The Modern Method for Manufacturing Steel

However, the basic technique was simple, and the use of iron gradually spread. As useful as it was compared to other materials, iron had disadvantages. The quality of the tools made from it was highly variable, depending on the region from which the iron ore was taken and the method used to extract the iron.

Introduction to Iron and Steel

2 is used to reduce iron ore pellets to "direct reduced iron" (DRI, or sponge iron). The reaction takes place in a shaft furnace, a type of furnace that uses gas reductants to make DRI. The operating temperature can be fairly low, around 800°C. The DRI is then fed into an EAF and turned into steel by further processing it and adding carbon.

Iron processing | Britannica

Whether you're producing steel from iron ore or scrap, and your end product is several inch-thick slabs or galvanized sheet less than a millimeter thick, you are always looking for technologies that improve each stage of the steel manufacturing production process, from incoming raw materials to the final coating line.. We have gathered all our steel manufacturing information and created a ...

The future of steelmaking

Similarly, the iron ore may have embedded emissions unless it is extracted and processed in an emissions-free manner. Furthermore, small amounts of carbon must be added to the EAF in the H-DR process to make steel from iron. In commercial direct reduction, carbon …

Decarbonization in steel | McKinsey

Midrex Process for Direct Reduction of Iron Ore. Midrex is an ironmaking process, developed for the production of direct reduced iron (DRI). It is a gas-based shaft furnace process is a solid state reduction process which reduces iron ore pellets or lump ore into DRI without their melting using reducing gas generally formed from natural gas.

How is Steel Produced? | World Coal Association

Direct reduced iron (DRI) process. In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the so-called direct reduced iron (DRI) process (secondary route).The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.

The Extraction of Iron

Technology principles: An alternative to BF‑CO steel production, the DRI route reduces solid iron ore using carbon monoxide and hydrogen. Direct reduction based on hydrogen The new smelting reduction process would circumvent the need for iron ore agglomeration and coking, avoiding 20% of the CO 2 emissions of the standard BF‑CO route.
