Small Metal Casting Furnace For Sale-60 lbs Bronze/Aluminum - $700 (Deland, Fl)

Casting | | | | | | | | |

Hello! I am selling this portable furnace built for bronze. brass, or aluminum casting. This will work for any metal with a melting point lower the 2500 degrees. The face of the interior is filled with 3000 degree refractory, then backed with 2600 degree. 3000 was use for the face to protect against the heat, but due to the fact that it is extremely heavy, the lighter 2600 degree refractory was used to fill out between the face and the furnace walls. The furnace comes equipped with a blower for delivering propane to the center. It also comes with a propane regulator... propane tank not included. I am also including a set of crucible lifting tongs and crucible shank as well as a crucible used with silicon bronze... it is a bilge shaped B20, as well. I can also throw in three skimmers used for bronze. You may be able to fit a larger crucible other then a B20, but the B20 is the only one to have been used so far. The shank is useable with up to a #30 crucible. The furnace is portable, built on cast aluminum wheels. There is a wide hole for charging the crucible with more metal, but a separate cover to keep the heat in when not charging. The total weight runs right around 300 lbs. This is a great economical choice for low-volume casting.
