Industrial furnace from 1907. A metallurgical furnace, often simply referred to as a furnace when the context is known, is an industrial furnace used to heat, melt, or otherwise process metals. Furnaces have been a central piece of equipment throughout the history of metallurgy; processing metals with heat is even its own engineering specialty ...
In 1847, iron rails for the Erie Railroad were made at the site. By 1865, Scranton, Grant & Company had the largest iron production capacity in the United States. In 1875, steel production was initiated at the site. By 1880, the furnaces produced 125,000 tons of pig iron, one of the main uses of which was the manufacture of t-rails.
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 ...

The district includes four contributing buildings, one contributing site, and one contributing structure.
Double puddling furnace layout. The hearth is where the iron is charged, melted and puddled. The hearth's shape is usually elliptical; 1.5–1.8 m (4.9–5.9 ft) in length and 1–1.2 m (3.3–3.9 ft) wide. If the furnace is designed to puddle white iron then the hearth depth is never more than 50 cm (20 in).

The Fitchburg Furnace is a historic iron furnace located in the Daniel Boone National Forest in Estill County, KY. The furnace is the world's largest charcoal iron furnace and the last to be built in Kentucky. The structure was state of the art in its time. With core of the furnace consisted of twin stacks built of local sandstone using ...
Depending on the proportions of steel scrap, DRI and pig iron used, electric arc furnace steelmaking can result in carbon dioxide emissions as low as 0.6 tons CO 2 per ton of steel produced, [12] which is significantly lower than the conventional production route via blast furnaces and the basic oxygen furnace, which produces 2.9 tons CO2 per ...
