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
