increases in iron ore yield in steel making

Emerging Technologies for Iron and SteelmakingDOI /s 016 5 SpringerLink

Pre reduced iron ore coal and oxygen are injected into a deep steel making slag The coal is devolatilized and partially combusted to CO The uncombusted coal char either directly reacts with iron oxide dissolved in the slag to form iron and carbon monoxide or dissolves in the iron bath Dissolved carbon in the metal also reacts with iron oxide in the slag to form iron and carbon monoxide Composite briquettes or pellets consisting of iron ore carbon and a binder are a source of direct reduced iron DRI In the handling of green and reduced briquettes high strength is important to minimize briquette breakdown The use of charcoal as a source of carbon rather than coal provides a

Use of Direct Reduced Iron in Electric Arc Furnace Sponge Iron Consumption against Metallic Steel Scrap In

In the meantime steel making in EAFs can benefit significantly from optimizing practices increasing further the use of chemical energy and correctly using the direct reduced iron DRI Historically use of DRI in EAF was for the production of high quality low residuals steels with the anticipated expense of specific energy kWh/ton tap to tap time and loss of yield Current educated use of Sponge Iron Consumption against Metallic Steel Scrap In Secondary Steel due to rising production worldwide the demand for iron ore is also going to increase both in India and World over Calibrated lump ore which is already scarce is going to be a weak link in the supply chain for increased production of steel In the near future only low grade iron ore fines are going to be available

Ironmaking Processes Shropshire HistoryPig Iron Manufacturing Process

The oxygen in iron oxide and other impurities decarburize the pig iron by burning the carbon away forming steel To increase the oxygen contents of the heat more iron ore can be added To increase the oxygen contents of the heat more iron ore can be addedThe direct production of steel from iron ore in the electric furnace has never passed beyond the laboratory stage Just as pig iron can be produced from iron ore in the electric furnace so can pig steel be produced by a close regulation of the carbon content of the charge
