Here is an excerpt from the new Metal Casting Forum Cupola Furnace information webpage:
“Cupola furnaces are among the most popular with backyard foundries. Many casters construct their own cupola which proves to be cost effective and highly efficient if done properly. Since cupola furnaces can achieve high melting temperatures they are primarily used for the melting of iron and bronze, though aluminum can also be melted when attention is paid to keeping the temperature low. The primary fuel source for cupola furnaces are coke using limestone for flux.
By not using a crucible, the Cupola furnace is able to melt the metal at a faster rate. While individual designs of these furnaces differ due to varying resources and design ideas, the basic component of a cupola furnace is the same. The cupola furnace must be elevated above the ground and installed with a drop bottom usually hinged, which will allow the excess metal, fuel source, and other waste to drop from the furnace. The tap hole and shaft which will allow the molten metal to flow from the furnace and into the ladle and air shafts are also required. A slag tap hole can be placed on the furnace usually in the back, higher then the tap hole, which will allow the slag to flow out easily.”
