• : Metallurgy of Iron and Steel

     · 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.
