Former AHM blast furnace in Port of Sagunt, Valencia, Spain. 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]
Sloss Furnaces is a National Historic Landmark in Birmingham, Alabama in the United States. It operated as a pig iron -producing blast furnace from 1882 to 1971. After closing, it became one of the first industrial sites (and the only blast furnace) in the U.S. to be preserved and restored for public use. In 1981, the furnaces were designated a ...
The Gysinge forge was founded in 1668, when Peder Swensson received on April 29 the privileges to create a blast furnace. Access to energy from the river as well as to wood made this site, which had previously been used as a summer pasture site for the villagers of Klappsta, a particularly favorable location.
Two blast furnaces have been preserved, including outer frames, furnaces and Cowper stoves. A protective paint coating minimizes the rusting effects on the blast furnaces. Blast furnace 6 is accessible to the public as part of guided tours. A colorful light installation illuminates the entire area at nighttime. [8] [9] Sulzbach-Rosenberg, Bavaria
Blast furnace gas. An early internal combustion blowing engine of around 1900, powered by furnace gas. Blast furnace gas (BFG) [1] is a by-product of blast furnaces that is generated when the iron ore is reduced with coke to metallic iron. It has a very low heating value, about 93 BTU /cubic foot (3.5 MJ/m 3), [2] because it consists of about ...
The Tannehill Ironworks is the central feature of Tannehill Ironworks Historical State Park near the unincorporated town of McCalla in Tuscaloosa County, Alabama. [1] Listed on the National Register of Historic Places as Tannehill Furnace, it was a major supplier of iron for Confederate ordnance. [2] Remains of the old furnaces are located 12 ...
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 wrought iron. Blast furnaces, which produce pig iron, have largely superseded bloomeries.
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 known as pyrometallurgy .
