IRON MAKING IN MINI BLAST FURNACE (MBF) - IDC-Online

The Blast Furnace ironmaking process had, until recently, been the unchallenged method of making hot metal on a large scale. Till 1990, the blast furnace route of ironmaking had about 97% (527mt) share of global iron production. Since then many other alternative processes of iron making have arisen e.g., Shaft Furnace DR processes (MIDREX, HyL ...

Blast furnace Facts for Kids - Kiddle encyclopedia

Process. Ore, limestone and carbon in the form of coke are put into the top of the blast furnace in layers.At the same time, hot air called "wind" is blown inside the furnace. Special nozzles called "tuyeres" are used to put the air in the furnace. The nozzles are at the bottom of the furnace. This process is called "blasting". It is why it is called a "blast furnace".
