DRI Direct Reduced Iron DRI is reduced iron pellet and/or lump, which is cooled and discharged at low (ambient) temperatures. The process characteristics allow for independent control of the DRI metallization and carbon levels. Metallization can be adjusted at will, typically around 94% and higher. _ DRI carbon levels can be selected in

Direct reduced iron is iron ore in the form of lumps, fines or pellets that have had the oxygen removed by using hydrogen and carbon monoxide. Typical sources of carbon monoxide are natural gas, coal gas, and coal. Other energy inputs into the production process often include oil and electricity. Since much of the energy used is in the form of ...

The direct reduced iron is produced by reducing iron ore with reformed natural gas, whose principal components are hydrogen, carbon monoxide, and methane. The scrap, along with direct reduced iron, is then melted in an electric arc furnace (denoted EAF hereinafter) to produce molten steel which is subsequently processed by the continuous ...

Direct Reduced Iron (DRI): This iron production process directly reduces iron ore in solid-state with the reaction temperature below the melting point of iron. Reducing gases are produced from natural gas (gas-based DRI) or coal (coal-based DRI) called syngas, a mixture of H2 and CO.

Direct reduced iron (DRI) is also known as sponge iron. It is produced by the reduction of iron ore (in the form of lumps or pellets) by either non-coking coal or a reducing gas produced by reforming of natural gas. The reducing gas can also be produced by the gasification of coal. The reducing gas is normally a mixture.
