Understanding How The Indian Steel Industry Works | Part 1

Sintered iron ore and coke are layered inside a 100 m long furnace, then hot air at 1200 degree Celsius is blown into the blast furnace from the bottom causing the coal to burn and this heat, in turn, burns the iron ore to create molten iron at a temperature of 1500 degree Celsius. This is also called hot metal (pig iron) in the industry.

Blast furnace - Wikipedia

Blast furnaces operate on the principle of chemical reduction whereby carbon monoxide converts iron oxides to elemental iron. Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and reduce the iron oxide. The blast furnace operates as a …
