A bloomery is a type of metallurgical furnace once used widely for smelting iron from its oxides. The bloomery was the earliest form of smelter capable of smelting iron. Bloomeries produce a porous mass of iron and slag called a bloom. The mix of slag and iron in the bloom, termed sponge iron, is usually consolidated and further forged into ...
An open-hearth furnace or open hearth furnace is any of several kinds of industrial furnace in which excess carbon and other impurities are burnt out of pig iron to produce steel. [1] Because steel is difficult to manufacture owing to its high melting point, normal fuels and furnaces were insufficient for mass production of steel, and the open ...
Coke (fuel) Raw coke. Coke is a grey, hard, and porous coal-based fuel with a high carbon content. It is made by heating coal or oil in the absence of air.

Steel mill. Integrated steel mill in the Netherlands. The two large towers are blast furnaces. A steel mill or steelworks is an industrial plant for the manufacture of steel. It may be an integrated steel works carrying out all steps of steelmaking from smelting iron ore to rolled product, but may also be a plant where steel semi-finished ...
Washington Iron Furnace is an historic iron furnace, located in Rocky Mount, Franklin County, Virginia. The granite furnace was built around 1770, and measures 30 feet high on its south face. It helped establish industry in the county, and was listed on the National Register of Historic Places in 1973.
