In 1874, the first furnace of the Glendon Iron Company was rebuilt by William Firmstone with the intent of modernizing it. After being rebuilt, the furnace was 63 feet (19 m) tall, and its bosh had a diameter of 18 feet (5.5 m). In 1881, the second and third furnaces were rebuilt by Frank Firmstone, William Firmstone's son.
Ferrous metallurgy is the metallurgy of iron and its alloys. The earliest surviving prehistoric iron artifacts, from the 4th millennium BC in Egypt, [1] were made from meteoritic iron-nickel. [2] It is not known when or where the smelting of iron from ores began, but by the end of the 2nd millennium BC iron was being produced from iron ores in ...
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 ...
Graphite electrodes carry the electricity that melts scrap iron and steel, and sometimes direct-reduced iron (DRI), in electric arc furnaces, which are the vast majority of steel furnaces. They are made from petroleum coke after it is mixed with coal tar pitch. They are extruded and shaped, then baked to carbonize the binder (pitch). This is ...
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 ...
Added to NRHP. September 6, 1991. The Scranton Iron Furnaces is an historic, American manufacturing site that preserves the rich heritage of iron making in Pennsylvania. It is located in Scranton, near the Steamtown National Historic Site. The site has been managed by the Pennsylvania Historical and Museum Commission since 1971 and is part of ...

The Paradise Furnace, also known as the Mary Anne Furnace, is a national historic district that is located in Trough Creek State Park in Todd Township in Huntingdon County, Pennsylvania . It was listed on the National Register of Historic Places in 1990.
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 ...
