DRI is successfully manufactured through either gas or coal-based technology. Iron ore is reduced in solid state at 800-1050 c either by reducing gas (H2+CO) or coal. The direct reduction process uses palletized iron or natural ‘lump’ ore. Process. Sponge iron making is a process in which iron ore lumps (typically 5mm-18mm size) are tumbled ...
Abstract: Today India stands as the largest producer of coal based sponge iron through rotary kiln process using calibrated ore and non coking coal. However, Rotary kiln process suffers from serious limitations like low productivity and pollution. In this respect fixed bed Tunnel kiln furnace are evolving as an alternative to Rotary kiln process.

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.
Presently, coal based units produce ~90% of the total sponge iron in India. Moreover, India’s crude steel production grew at a CAGR of 6.75% between 2006-16. The production of EAF steel as a share of total steel grew at a steady rate, from 57% (2006) to 68% (2012), thereafter, this declined to ~57% in the past four years, ending 2016.

Sponge Iron Background:: DRI Process:: The majority of DRI units in India are coal based. In a coal based DRI unit, non-coking coal and iron ore along with limestone or dolomite in the required size range and quantity are continuously fed into the feed – end of an inclined rotary kiln through a feed pipe.
Aug 07, 2016 • Sponge iron produced by the process will be the high grade which contains 80% Fe, 12% FeO and 8% gangue material. After separation of sponge iron in the magnetic screen/pulley, the remains are collected as char. Char has good amount of fixed carbon (25% - 30%) and moderate GCV (2500 - 2600 Kcal/Kg).
