Iron And Steel Production
Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for fuel. Iron oxides, coke and fluxes react with the blast air to form molten reduced iron, carbon monoxide (CO), and slag. The molten iron and ...

3A3. Direct Iron Ore Smelting Reduction Process (DIOS)
The Direct Iron Ore Smelting Reduction Process (DIOS) directly uses noncaking coal in a powder or granular form, and iron ore without the use of coke or a sintering process, which are normally required in blast furnace processes. The noncaking coal is directly fed to a smelting reduction furnace, while the iron ore is preliminarily reduced before being fed to the furnace, thus producing molten ...

The direct reduction process removes this bonded oxygen in the iron ore pellets at elevated temperatures by a reducing gas, which is produced from natural gas. The reduction occurs in a sealed lowpressure reduction reactor, which is not vented to the atmosphere. The iron oxide pellets enter the reactor through the feed pipes, are reduced to metallic iron and are discharged from the furnace ...
