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 (line) are continuously.

Pig iron - Wikipedia

Pig iron is an intermediate product of the iron industry. Crude iron as first obtained from a smelting furnace, in the form of oblong blocks. Pig iron has a very high carbon content, typically 3.8–4.7%, along with silica and other constituents of dross, which makes it very brittle, and not useful directly as a material except for.
