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 ...
The blast furnace process is characterised by the variety and complexity of the phenomena of gas dynamics, charge transfer, heat transfer, recovery, softening, and other phenomena.
