Blast Furnace

What Is The Use Of Blast Furnace

Blast Furnace Is used in the extraction of Iron from its ore Haematite or Fe2O3 (Which is practically rust).

What is Put In The Blast Furnace

Coke/C, Calcium carbonate/CaCO2,Haematite/Fe2O3

What happens

Hot air is blown through an opening in the blast furnace which causes the calcium carbonate into calcium oxide and carbon monoxide. The calcium oxide reacts with sand or silicon dioxide forming slag which is used for laying roads.

The carbon monoxide and coke break the iron ore to form carbon dioxide, carbon monoxide and molten pig iron. The gases escape through tubes on top of the blast furnace and the pig iron is removed and used for different purposes in different industries.
