Iron processing - Smelting, Refining, Alloying: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.

The blast furnace process has been the primary method for producing iron for many decades. The blast furnace is a refractory-lined circular shaft 100 to 200 feet high, with an internal diameter between 20 and 45 feet. The refractory wall lining typically measures two feet or more in thickness and contains more than 2,500 tons of refractories.

Molten iron is produced in a blast furnace by the following steps: 1. Charge (solid iron ore, coke, and limestone) is constantly dumped into the top of the furnace. 2. A blast of hot air is blown into the furnace from the bottom. 3. Coke is the fuel that supplies additional heat, increasing the temperature of the charge. 4.

It mostly describes the iron blast furnace as a counter current gas-solids dual heat and oxygen exchanger. The onset of coke gasification (orelse of iron oxide direct reduction), leads to a two-zones exchange model. This theory is used to look back at the operation of the earlier and smaller iron furnaces such as the early XIXth century ...
