Question:
Write down the reactions taking place in Blast furnace-related to the metallurgy of iron in the temperature range 500-800 K.
Solution:
These are the reactions that happen in the blast furnace at the 500K-800K range.
3Fe2O3 + CO → 2Fe3O4 + CO2
Fe3O4 + CO →3FeO + 2CO2
Fe2O3 + CO → 2FeO + CO2
