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 .
Furnace choice is dependent on the alloy system quantities produced. For ferrous materials EAFs, cupolas, and induction furnaces are commonly used. Reverberatory and crucible furnaces are common for producing aluminium, bronze, and brass castings. Furnace design is a complex process, and the design can be optimized based on multiple factors.
Principio Furnace and village is in Cecil County, Maryland, 4 miles (6.4 km) northeast of Havre de Grace. The Principio Iron Works were started here in 1719 by Joseph Farmer with British capital and an ironmaster, John England. By the 1740s, it had become one of the most successful colonial ironworks, producing pig iron for sale in
During the Han dynasty (202 BC – 220 AD), most, if not all, iron smelted in the blast furnace was remelted in a cupola furnace; it was designed so that a cold blast injected at the bottom traveled through tuyere pipes across the top where the charge (i.e. of charcoal and scrap or pig iron) was dumped, the air becoming a hot blast before ...
Carrick Furnace is a historic iron furnace located at Metal Township in Franklin County, Pennsylvania. The property includes the limestone furnace stack, a Peter L. Weimer blowing engine (1879), boilers for the steam engine, and the charging ramp, engine house, and cast house foundations. The furnace was built about 1828, and measures 30 feet ...
Originally a charcoal furnace, the old blast furnace at Coalbrookdale was leased in 1709 by Abraham Darby I, who used it to make coke pig iron and created the first long-term business to do so. The furnace remained in use until the 19th century and now forms part of the Ironbridge Gorge Museum Trust 's Museum of Iron .
Melting metal for casting; Calcination of ore in a rotary kiln prior to smelting; Pyrolysis of chemical materials; Heating limestone with clay in the manufacture of Portland cement, the cement kiln; Heating limestone to make quicklime or calcium oxide, the lime kiln; Heating gypsum to make plaster of Paris; For cremation (at high temperature ...
The advantage of the induction furnace is a clean, energy-efficient and well-controlled melting process, compared to most other means of metal melting. Most modern foundries use this type of furnace, and many iron foundries are replacing cupola furnaces with induction furnaces to melt cast iron, as the former emit much dust and other pollutants ...
