Direct Reduced Iron | Industrial Efficiency Technology ...

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.

Direct reduced iron process - tec-science

Direct reduced iron (DRI) process. In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the so-called direct reduced iron (DRI) process (secondary route).The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.

DRI – Direct reduced iron. Normally in the form of sponge pellets or lumps varying between 6 and 25mm nominal diameter, but often 8 to 12mm diameter. The IMO BC Code classes this product as "a material that is hazardous only when in bulk" (MHB). It can be found under the BC Code as BC015.

Direct Reduced Iron and its Production Processes – IspatGuru

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.
