iron ore reduction in rotary hearth furnace

rotary hearth furnace iron ore reduction rotary hearth furnace iron ore reduction As a leading global manufacturer of crushing and milling equipment XSM rotary hearth furnace iron ore reduction offer advanced rational solutions for any sizereduction requirements including quarry aggregate grinding production and complete plant plan

reduction of iron ore Most of the DRI plants use shaft furnace reactors developed by MIDREX 43 and HYLEnergiron 45 technologies Shaft furnaces are moving bed countercurrent reactors Rotary hearth furnaces are used when coal is used as the source for production of reducing gases 33

Iron Ore Reduction In Rotary Hearth Furnace 20170825 A coalbased reduction process using a rotary hearth furnace RHF in collaboration with MIDREX Technologies a subsidiary of Kobe Steel in the USA This process involves carbon composite agglomerates in the form of pellets or briquettes laid on the hearth of the RHF in which the composite agglomerates are heated and reduced in a static manner

The pellets travel through the rotary hearth furnace and are heated to 1250–1350 °C by burners placed throughout the length of the furnace The rapid reduction rate of 12 minutes is attributed to the high reduction temperatures and the close contact of the reductor and the iron oxide particles
