Carbon-composite briquetting of iron ore fines & fast-reduction into DRI in the rotary hearth furnace
We offer the technology for carbon-composite briquetting & subsequent reduction of iron ore into DRI in the rotary hearth furnace from a reputed manufacturer in China, in capacities from 70,000 tons to 320,000 tons per year.
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. Hot DRI briquettes can be directly charged into the Electric arc furnace / Gas Oxygen Refiner (GOR) to make steel ……. Click here for more details
