Fine iron ore smelting process in cupola furnace can be considered to be similar with the process in blast furnace with a little difference on kinetic reaction. In the blast furnace, iron ore or iron oxide is reduced by carbon dioxide (CO) formed as a result of carbon change in reduction environment [2] .

The Cupola. The Cupola is at the heart of the modern iron caster's foundry and can be used for industrial large-scale operations as well as small person applications. Cupolas are the most efficient and fastest furnaces for melting iron.[1] The Cupola has been used for many years; in his book Pyrotechnia (1540), Vannoccio Biringuccio writes ...

Chat Online (PDF) Operability Analysis of Direct Reduction of Iron Ore . Direct reduction of low-grade iron ore pelleted with coal was investigated using a pilot-scale rotary kiln.

and charcoal could be made as long as the iron ore lasted. Reduction of iron ore to pig iron became big business in the late 1800's and early-1900's. Local blast furnaces furnished an outlet for much of the early iron ore production. Up to 1903, all Michigan pig iron was smelted with charcoal. At that time coke from coal was introduced

This iron was sent to local foundries to be made into tools, implements, and machinery. As a forerunner in iron technology of the 1800's, Bluff Furnace was the first in the southern Appalachian region to use coked coal as a fuel in a modern cupola-style furnace. It …

cupola furnace, in steelmaking, 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.
