The past 5 years have seen increases in the supply and use of Pig Iron, Direct Reduced Iron (DRI), and Hot riquetted Iron (HI) in the EAF. • DRI should not be considered as a scrap substitute but rather as a source of clean iron units that can be used to supplement and enhance the scrap charge

The iron used in the steelmaking process is currently chemically reduced from iron ore through the use of fossil resources – natural gas or coal. This process is known as Direct Reduced Ironmaking (DRI). Carbon combines with the oxygen in the iron ore, producing metallic iron and a carbon-rich process gas, according to the

In a DR process, iron ore pellets and/or lump iron ores are reduced by a reducing gas to produce DRI or hot briquetted iron (HBI). Depending on the generation …

This product is known as direct reduced iron (DRI) or sponge iron. Processes that produce iron by reduction of iron ore (in solid state) below the melting point are generally classified as DR ...

The metallic iron in this process is produced by the reduction of iron oxide below the fusion temperature of iron ore (1535 deg C) by utilizing carbonaceous material present in the non-coking coal. As the iron ore is in direct contact with the reducing agent throughout the reduction process, it is often termed as direct reduced iron (DRI).

A Direct Reduced Iron (DRI) plant. The DRI process is both effective and flexible. The technology has a broad range of benefits that includes the following: The process allows producers to use various hydrocarbon sources and off-gases making it an ideal technology to support the staged transition to hydrogen.

The global direct reduced iron market was valued over US$ 21.87 Bn in 2020. It is estimated to expand at a CAGR of 8% from 2021 to 2031.
