Blast furnace
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper Blast refers to the combustion air being supplied above atmospheric pressure In a blast furnace, fuel (coke), ores, and flux (limestone) are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with Blast furnaces (BF) are still the dominant process for making iron in the world Blast furnaces are charged with iron ores in the form of pellets, sinter and/or Special Issue "Iron Ore Reactions and Phenomena in a Blast Furnace"
