Blast Furnace System Industrial Efficiency Technology
· In a blast furnace (BF) the iron oxides are reduced and the resulting iron is melted. Approximately 70 of the global steel production involves the use of BFs. Sizes of BFs installed cover a very wide spectrum ranging from less than 100 m3 to more than 5000 m3. Larger BFs have less heat losses and enable installation of heat recovery equipment more cost effectively (IEA 2007.p. 116).

Handling of Hot Metal in Blast Furnace Iron Making
· Handling of Hot Metal in Blast Furnace Iron Making. Hot metal (HM) is produced by the reduction of descending ore burden by the ascending reducing gases in a blast furnace (BF). It is liquid in nature and gets collected in the hearth of the BF. From the hearth the HM is tapped from the taphole of the BF after an interval of time.
