The Blast Furnace (BF) is a furnace used in the iron-making process. It uses iron ore and limestone as input, metallurgical coal (converted to coke) as a reducing agent, and creates pig iron (also known as crude iron or hot metal) as output. This pig iron can then be used in other furnaces, like the Basic Oxygen Furnace (BOF) or Electric Arc Furnace (EAF), to …
