The product of the blast furnace is pig iron, which contains 4–5% carbon and usually some silicon. To produce a forgeable product a further process was needed, usually described as fining, rather than refining. From the 16th century, this was undertaken in a finery forge. At the end of the 18th century, this began to be replaced by puddling (in a puddling furnace), which was in turn gradually superseded by the production of mild steel by the Bessemer process. nutech renewablesSmelting is typically classified into two procedures: the wet process and the dry process. Electrolytic iron is considered the “wet process” since electrolysis requires electric charges to move through a liquid solution. This action causes a chemical reaction called electrolytic refining.
