· The overall reaction for the production of iron in a blast furnace is as follows: () F e 2 O 3 ( s) + 3 C ( s) → Δ 2 F e ( l) + 3 C O ( g) The actual reductant is CO, which reduces Fe 2 O 3 to give Fe (l) and CO 2 (g) (Equation ); the CO 2 is then reduced back to CO by reaction with excess carbon.

Get PriceAfter the iron ores are dressed, they are calcined and roasted. The calcination consists in heating ores in presence of air so that they are oxidized. The water and carbon dioxide are removed from ores by calcination. The roasting consists of making the ores hot and very dry. It is adopted to dissipate the volatile parts, especially sulphur, by ...
Get PriceThe process starts in the center of the wheel with the three main ingredients of iron in the form of iron ore, coke and lime, which are fed into a blast furnace to produce molten iron. The molten iron is mixed with recycled steel scrap and further processed in a basic oxygen furnace to make steel.
