Carbon-composite briquetting of iron ore fines & fast

Iron-carbon composite is produced by mixing iron ore fines & anthracite coal fines, and densified by briquetting. These briquettes are dried & finally reduced in the rotary hearth furnace in 30-40 minutes. As the carbon particles directly touch the oxygen particles & high temperatures of 1,250-1,350°C are maintained in the process, the reduction is much faster.
