Circored Fine Ore Direct Reduction Plus DRI Smelting: Proven
Preheating the iron ore fines to 850–900 °C in a separate CFB reactor for calcining prior to charging in the primary CFB reduction stage This method also allows the processing of magnetite ores, which can be difficult to reduce as the preheating stage oxidizes the magnetite to hematite
The future of steelmaking Roland Berger
2 is used to reduce iron ore pellets to "direct reduced iron" (DRI, or sponge iron) The reaction takes place in a shaft furnace, a type of furnace that uses gas reductants to make DRI The operating temperature can be fairly low, around 800°C The DRI is then fed into an EAF and turned into steel by further processing it and adding carbon
