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. ... but also because production is primarily coal based. In india DRI plants can be easily ...

Sponge iron will be manufactured through the coal-based route in which crushed iron ore is converted into DRI. A long, slightly inclined, slowly rotating kiln is employed to carry out the reduction. The process would be designed to carry out reduction using solid reductant like non-coking coal.
From 2003, coal based sponge iron route dominated because of limited availability of natural gas and fast growing demand of metallics. In fact, no gas based sponge iron/HBI plant came up after 1994 (19 years). During 2003-2008, there had been a rapid growth of coal based sponge iron plants.
SPONGE IRON PLANTTo control the sulphur in sponge iron, the sulphur in coal should be one percent maximum. 4) Good reactivity:- An important step in solid state
Sponge Iron Plant Process Equipment. 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 1200 °C).

Galaxy Refractories has high quality iron products and supplies it to steel plants. The company makes this product in two ways. First method makes use of coal to reduce iron ore into metallic iron and the other method employs reducing gases for reduction of iron into sponge iron. Sponge iron made using reducing gases is called hot briquette iron.
