Iron Ore Sintering Process In Steel

Iron Ore Sintering Process In Steel

Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together After cooling the sinter is broken up and screened to yield blast furnace feed and an undersize fraction that is recycled.The Making of Iron amp Steel Sinter is better suited to this practice than pellets Iron Ore Agglomeration Sinter Process The sinter process was introduced around 1910 to treat flue dust extracted from blast furnace exhaust gases It was quickly adapted to agglomerate fine ore and its use spread rapidly At the sinter plant preblended fine ore is.
