The unmelted iron ores still contain non-reduced iron oxides. An unfavourable accumulation of ores at the contact points can also make gas flow difficult and thus leave non-reduced iron ore behind. At the latest, however, when the melting process occurs in the deeper and hotter zones of the blast furnace, iron ores can be almost completely reduced.

Blast Furnace - Basic Oxygen Furnace (BF-BOF): This is the dominant steel production route in the iron and steel industry, involving the reduction of iron ore to pig iron in the blast furnace. BF-BOF operation relies almost entirely on coal products, emitting ~70% of CO2 in the integrated plant (BF iron making).

A blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore, coke, and limestone are dumped from the top, and a blast of hot air is blown into the bottom. All the three ingredients are crushed into small round pieces and mixed and put on a hopper which controls the input.

The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. The raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the final product of liquid slag and liquid iron.

From the iron ore by washing with water. Calcination or roasting:-It is the process of expelling moisture, Co 2, So 2, and arsenic from the iron ore by heating in shallow kilns. Smelting:-It is the process of reducing the iron ore with carbon in the presence of a flux. The smelting is carried out in a large tower called a blast furnace.

125 Iron And Steel Production.
