Direct reduced iron (DRI), also called sponge iron,[1] is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron ...

Industrially iron is produced from iron ores, principally hematite (Fe 2O3), magnetite (Fe 3O4) by a carbothermic reaction that is reduction with carbon, in a blast furnace at temperature about 800-1600 OC. In blast furnace, iron ore, carbon in the form of coke, and

The concentration and chemical bonding state of carbon in direct-reduced iron (DRI) might affect DRI melting temperature and rate. The effects of carbon bonding state and concentration were evaluated with high-temperature confocal microscopy, differential scanning calorimetry, and by monitoring the carbon monoxide generation rate from reaction between DRI pellets and a laboratory slag-steel melt.

Direct-reduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture majority of hydrogen (H2) and carbon monoxide (CO) which acts as reducing agent.

route is that the raw materials do not need to be treated ('beneficiated'), e.g. by sintering and making coke, and that they can adjust well to low-grade raw materials. On the other hand, more pri - mary fuels are needed, especially natural gas for direct reduced iron

In the indirect reduction zone, the iron oxide contained in the iron ores is reduced by carbon monoxide gas, whereby the iron ores are not melted! Direct reduction zone If the iron ores, which have not yet been reduced, move further down in the blast furnace, then the carbon can also directly reduce the iron oxides contained in the ore due to the high temperatures.

Direct reduced iron (DRI) is the product which is produced by the direct reduction of iron ore or other iron bearing materials in the solid state by using non-coking coal or natural gas. Processes which produce DRI by reduction of iron ore below the melting point of the iron are normally known as the direct reduction (DR) processes.

Direct Reduced Iron Emirates Steel has the capacity to produce and sell DRI (Direct Reduced Iron) as a semi-finished product. DRI is a source of iron produced by heating an iron pellet at temperatures high enough to reduce its oxygen content, but below its melting point.

19/7/2020· Iron making The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here.Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.
