In steelmaking, it is a vertical cylindrical furnace used for melting iron either for casting or for charging in other furnaces. René-Antoine Ferchault de Réaumur built the first cupola furnace on record, in France, about 1720. Cupola melting is still recognized as the most economical melting process; most gray iron is melted by this method.

Two raw materials that are used in a Cupola furnace include rocks and briquettes. The cupola is a vertical furnace that is similar to blastfurnaces.

The oldest surviving industrial furnace is the Cornwall Iron Furnace. The furnace is located in Philadelphia, Pennsylvania. It is from the year 1742 which means it is over 250 years old.

Iron is refined by a blast furnace. A furnace is filled with iron ore, coke (which is charcoal made from coal) and limestone. Huge amounts of air are blasted into the furnace, the calcium from the limestone combines with silicates (which are minerals containing silicon and oxygen) to form slag (which is run off ore from the furnace). A layer of liquid iron collects under the slag, at the bottom of the furnace. The liquid iron is periodically let out to cool. Charlie

A cupola furnace is not the same as a crucible furnace. A cupola furnace is a type of melting furnace used mainly for iron melting, while a crucible furnace is a type of melting furnace that uses a ceramic or graphite crucible to contain the molten metal. The names reflect the different structures and functions of the two types of furnaces.
A cupola is an observation dome on a building or vehicle, and it is also a type of blast furnace.
In essence nothing, a Cupola furnace is a type of blast furnace in that it is charged at the top and tapped at the bottom and air is blasted into the furnace via a wind belt and tuyres. A blast furnace in a steel works is a huge structure operated for long periods of time, it is charged with iron ore, coke and limestone and reduces the iron ore into pure iron. A Cupola furnace, as used in the foundry re melts pig iron, from the blast furnace, along with foundry scrap, steel scrap and scrap iron engine blocks and produced iron alloys of various specifications. A Cupola furnace is usually operated on a daily basis but some types can be continuously operated for several weeks
The melting loss of steel in a cupola furnace typically ranges from 5-10%. This loss is mainly due to oxidation, carbon pickup, and metal splashing during the melting process. Proper control of the furnace parameters and alloy additions can help minimize this loss.
A cupola furnace is a tall, vertical furnace used to melt iron and other metals. It works by charging alternate layers of metal and coke (carbon fuel) through a charging door at the top of the furnace. The coke is ignited, creating intense heat that melts the metal charge, which is tapped periodically from the base of the furnace.

yes for a small melting foundry its very essential because of its low working price and easy operation. no significant labor is needed for melting pig iron form cupola
