The "2 bucks" furnace. I wanted a small propane fired furnace for efficient aluminum and bronze melts. I figured that the coffee can furnace mentioned elswhere on the internet was too small, but metal 12 quart buckets seemed just right for my 4" diameter crucible.
In a fuel-fired furnace, operating the burner with excess air and direct flame impingement on the crucible surface will produce damaging oxidation of the crucible. In all furnaces, placing ceramic fiber between the crucible and its base or wedging ceramic fiber against the top edge of the crucible also will cause oxidation and cracking in those
Improper tongs can cause damage or complete failure of a crucible at the worst possible time. A disk of cardboard can be placed between the crucible and the furnace base prior to heating. This will burn off, leaving a layer of carbon in between and prevent the crucible from sticking to the furnace bottom.
Quality MIFCO also manufactures a complete line of safety crucible handling equipment, sand mullers and mixers, a vibratory riddle and pyrometers. A complete line of foundry safety apparel, vocational molders benches and tools, silicon carbide and clay graphite crucibles, and other foundry accessories are also stocked and available for quick shipment.
The included crucible is good, but for some reason does not have a pour spout. This can be fixed with a file, since it's graphite, but would be nice if it was already there. The way the box is packaged, the crucible is placed inside the furnace.
Get the Crucible Hot. Start up your melting furnace, whether you use charcoal or propane, to get the crucible hot enough to melt the aluminum cans or copper scraps. Your metal melting furnace kit should have a lid, which traps the heat in the furnace and speeds up the whole process. Once the crucible is red hot, it is ready to start melting.

What is a Crucible Furnace? A crucible furnace is one of the oldest types of melting ovens there is. It is a container that can be made from any material that has the ability to withstand very high melting temperatures. These ovens are categorized by how the molten metal is removed from the crucible:
Hello I have built a crucible furnace out of an hot water system steel tank. (app 3 feet high) It will be fired with Coke/Charcoal using a small cyclone. The crucible will be fixed in furnace and the furnace will tilt on a triangular frame allowing molten metal to pour into sand moulds.
Large size pot type crucible exclusively used for melting light alloys. Crucible with spout for tilting furnace. When placing your order keep in mind the important factors that need to be addressed when purchasing a crucible such as: Dimensions; Chemical composition of the crucible compared to the chemical composition of the melt
Crucible furnaces are the most common type of furnace used in industry. They are ideally suited for high pressure die casting, sand casting, gravity casting, permanent mold casting. Crucible furnaces are available in tilting and non-tilting versions. We offer crucible furnaces for aluminum and copper.
a crucible furnace is a casting facility, in which metal is melted in a pot (crucible) inside a furnace, before being poured into a mould, usually constructed from sand. a sand-tray beneath where molten metal is poured contains any spillage. there are tiles which are situated around the work chamber. silicon carbide heating elements are mounted horizontally behind these tiles.
1. Pit Type (Stationary) Furnace: As the name indicate, the pit furnace is made below the ground level, so that the crucible can easily be lifted, operating from the floor of the shop. The metal to be melted is put into the crucibles. The crucibles are placed in the heating chamber and sufficient coke being packed around and above the crucible.
Crucible furnaces are typically classified according to the method of removing the metal from the crucible: Tilting furnace, in which the molten metal is transferred to the mould or ladle by mechanically tilting the crucible and furnace body. Lift-out furnace, in which the crucible and molten metal are removed from the furnace body for direct
Crucible furnace design basics • Round furnaces are more efficient than square furnaces. • Furnaces should be sized according to the number crucible you are using. • They should be 6-12" wider than the diameter of your crucible. • The furnace height, with liner, should account for a crucible block which gets
