Direct reduced iron - Wikipedia

Process. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).

Sponge Iron Manufacturer India

Sponge iron produced using the non coking coal is called coal based sponge iron / DRI. For producing the sponge iron through this process requires high grade of iron ore and non coking coal. Gas Based DRI / HBI. In this process route, iron oxides are converted to the DRI / HBI by using natural gas in a vertical shaft furnace. For steel producers, it is a preferred metallic, energy efficient ...

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.
