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 forced or supplied above atmospheric pressure In a blast furnace, fuel , ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air sometimes with

Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as gangue The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent

Dec 04, 2016 Energy Use in US Steel Manufacturing This iron is often known as pig iron or hot metal as it is a liquid iron that flows from the bottom of the blast furnace This iron can be used for ironworks or as the starting material for creating steel Making Steel To create steel, carbon is released from the iron through either mechanical means
