Open-hearth furnace. 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 ...
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 ...
Ground granulated blast furnace slag is a latent hydraulic binder forming calcium silicate hydrates (C-S-H) after contact with water. It is a strength-enhancing compound improving the durability of concrete. It is a component of metallurgic cement ( CEM III in the European norm EN 197 ). Its main advantage is its slow release of hydration heat ...
Coke is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges . The unqualified term "coke" usually refers to the product derived from low-ash and low-sulphur bituminous coal by a process called coking.

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 supplied above atmospheric pressure. [citation needed] In a blast furnace, fuel ( coke ), ores, and flux ( limestone) are continuously supplied ...
An electric arc furnace ( EAF) is a furnace that heats material by means of an electric arc . Industrial arc furnaces range in size from small units of approximately one-tonne capacity (used in foundries for producing cast iron products) up to about 400-tonne units used for secondary steelmaking. Arc furnaces used in research laboratories and ...
