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.

Here are my melting and shell heating furnaces. The left hand one is the melting furnace "working on 100 lbs of bronze, the (cooler) right hand furnace has ceramic shells heating in it. Both are heated with propane at about 30 psi, via home built burners both forces air via small (and not so small) blowers. You can see the blower on the cooler, shell furnace. These furnaces are made with KalWool, 2 layers with high temp material on the inside layer of the melting furnace. It looks too hot to touch, but you can do a quick touch of the melting kiln without getting burned, the brightness of the wall material is really the flame shining thru the fibers, it is not "THAT" hot on the outside. The melting furnace was new in this picture, the shell kiln was about 10 years old and a new one was in the process of being built. Cost for both kilns was under $400 for both, with extra KalWool left over for cup covers, hole filling, patching, etc. The units were both lined internally with a kiln refractory made out of zircon and a binder (got it from a supplier in Oakland CA) which gave the interior walls some rigidity and protection from getting torn from shells and crucible tools and reflected the heat back into the furnace. I normally get about 10 years life out of a furnace before I need to build a new one. I can pick up and move either of these furnace indoors with ease by myself. After the first melt, about 1.25 hours from a cold start, the following bronze melts take about 45 minutes each, each melt being about 100 lbs of bronze.

refractory cement

| |

I want to build a speciality furnace. I have the resistor wire. I am looking for the white cement that one sees in kilns or laboratory furnaces. It is similar to pumice. You can cast the resistor wire inside of the cement. Does anyone know what the cement is called and where can I purchase it. Many thanks.


Foundry furnaces + sprinkler system

My university recently built a new building for its sculpture department, and has placed the foundry furnaces directly under a sprinkler system attached to the outdoor hood in our courtyard. It seems likely that the furnaces will set off the sprinklers as they are placed now.
