Direct Reduced Iron - Open Source Ecology

Direct-reduced iron is a metallic material formed by the reduction (removal of oxygen) of iron oxide (iron ore) at temperatures below the melting point of iron. DRI is produced by the use of a reducing gas (mostly a mixture of hydrogen and carbon monoxide). The temperatures for this process are significantly lower than those in a blast furnace ...

Wikizero - Direct reduced iron

Direct reduced iron (DRI), also called sponge iron, 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 oxides to metallic iron at temperatures

Direct Reduced Iron (DRI) International Iron Metallics Association

Use of Direct Reduced Iron (DRI) in the Electric Arc Furnace (EAF) for Steelmaking; Shipping and handling of DRI. Being a highly reduced material, DRI has a tendency to re-oxidise, an exothermic reaction. Thus, without appropriate precautions being taken in its handling, transport and storage, there is a risk of self-heating and fires.

Direct Reduced Iron Industrial Efficiency Technology Measures

Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BF-BOF and Scrap-EAF routes. In DRI, iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction. DRI can then be transformed to steel in electric arc furnaces. DRI production is common in Middle East, South America, India and Mexico.
