1. Cupola Furnace This type is commonly used for melting cast iron. The cupola furnace is vertical and has a refractory-lined chamber where layers of metal, coke, and limestone are charged from the top. Air is introduced at the bottom, and as the coke burns, it generates heat, melting the metal. This furnace is favored for its efficiency and continuous operation.
