In the steel plant considered here, direct reduced iron (DRI), produced by the coal-based SL/RN process, makes up 50% or more of the total iron charge. SL/RN DRI samples from a kiln cooler had high nitrogen contents (50-250ppm, depending on particle size), contributing to elevated nitrogen levels in liquid steel produced in the EAFs.

To reach a reduction degree of the hot DRI product of 95%, 1.4 t of iron oxide input material containing input materials per ton of DRI are required for the DR-NG as well as the DR-H 2 process. Based on NG which contains approximately 95% methane, the simulation results in an NG demand of approximately 259 m 3 STP t −1 DRI for the reference case.

Sponge iron, also called Direct-reduced iron (DRI), is formed, when naturally available Iron Ore which is an oxidised form of Iron (magnetite (Fe 3 O 4) or hematite (Fe 2 O 3)) is reduced to its metallic form. This reduction process occurs below the melting temperature of both metallic iron and its oxidised form. Though this

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.

DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.

Solid reduction process. Sponge iron is a highly processed form of iron ore which contains metallic iron in the range of 83-88% obtained by direct reduction without melting it. Due to high porosity, the resulting iron is called sponge iron. It is used as a raw material for manufacturing steel through electrical arc furnace and the induction
