A blast furnace is a steel cylinder lined with refractory. It operates continuously until the lining wears out, which takes many years to occur. The term blast furnace comes from the blast of hot air that is blown into the lower part of the furnace at between 1400º to 2100ºF. Molten iron is produced in a blast furnace by the following steps: 1.

Blast Furnace Route . Large European blast furnaces can produce around four million tonnes of iron per year. They rely on a chemical process called reduction: Iron ore is an iron oxide and to separate iron from oxygen carbon is needed as a so-called reducing agent. In the process it combines with the oxygen and forms carbon dioxide.
