The steel making units (LD process, open hearth, etc.) and cupola melting unit use oxidising atmosphere. (b) Furnaces with reducing atmosphere : In such furnaces the oxygen in the furnace is made absent by excess use of fuel that gives CO and hydrogen rich gases. The blast furnace and smelting furnace are typical examples for such furnaces.
