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 is an observation dome on a building or vehicle, and it is also a type of blast furnace.
First of all to correct that Cupola Furnace is used to melt Pig Iron to make Cast Iron not the Steel. As per practice the melting loss in Cupola furnace is cosiderd as arround 4.00 %. Sirajuddin Khan Bolan Castings Ltd. Karachi, Pakistan
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
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
Mainly the type of coke being used. The sulfur, ash and carbon content are different.

How do I build a cupola
The airshaft ventilation chimney and/or cupolas are rare structures these days, with at least some of those remaining being scheduled ancient monuments. The Nutbrook Colliery furnace ventilation cupola was designed to be remote from the airshaft itself, the furnace therefore being contained at the surface rather than at the base of the shaft. Connection to the airshaft itself would have been via a short inclined tunnel from beneath the base of the cupola. The furnace itself was accessed via an aperture in the side of the cupola, with the airflow (and thus furnace intensity) being controlled here according to the required up-draught. I've no idea whether the fresh air flow was mechanically assisted by the means of bellows, as was the case on similar installations elsewhere.This method of ventilation was seen as a considerable safety improvement on the underground furnace type, identified by a chimney constructed directly over a shaft. The underground furnace types were implicated in the ignition of mine gases, and could also ignite underground timbers leading to oxygen starvation within workings. At least one of the cupola type furnaces elsewhere operated until the 1950s, whereas by then the Nutbrook structure appears to have acted only as an additional downcast fresh air shaft for the fan ventilated workings of Woodside.
