摘要
The technology of direct reduced iron production is reviewed for a look at the future trend of alternative iron source out of the blast furnace route. High productivity direct reduced iron based on the demand on mini-mills has been established by the enlargement of furnace size and high temperature reduction. New technical development in the alternative iron world is a conjunction with rotary hearth furnace and iron ore agglomerate with :incorporated carbon. The carbon composite agglomerate is reduced in the time less than 10 min at 1300-1400 degreesC in the rotary hearth furnace. The carbon composite agglomerate and rotary hearth furnace technology allows the recycling of residues due to the next century.
