Blast furnace - Wikipedia
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 (coke), ores, and flux (limestone) are continuously Donald Wagner suggests that early blast furnace and cast iron production
