Blast furnaceWikipedia
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
