A crucible furnace is a liquescent or holding furnace in which the metal to be kept warm or melted is located in a crucible. A eminence is made here between tilting and ladling furnaces. Used crucible furnaces are used for all coarse casting processes such as die casting, permanent mould casting or sand casting. They are ideal for melting and holding aluminium, brass, zinc, lead and tin alloys. Crucible furnaces for aluminium alloys are manufactured with a capacity of up to 1.5 ton nes. Depending on the application and the want mellow temperature, different designs, crucibles, mechanisms and techniques for estrus transfer are used. There are graphite crucibles, crucibles made of hurl iron, special mold iron, cast steel, silicon carbide crucibles and sheet steel.

The operating principle of crucible furnaces

Depending on your needs, you can purchase crucible furnaces from us that are heated electrically, with gas or with oil. however, the heating system chemical element is the central component of every resistor furnace. here, heat is generated by the current menstruate through ( Joule estrus ), which is transferred to the load or crucible by conduction and convection. The exception here is the most late furnaces with immersing heating elements, which in call on offer diverse advantages in melting operation. crucible furnaces for aluminum alloys have to reach about 1,300 °C, a value that is best achieved by ceremonious metal-wire heated furnaces.

Advantages and disadvantages of crucible furnaces in foundries

Used crucible furnaces have many advantages and are characterised by their fabulous durability and ease of operation and alimony. initiation is relatively simple, they are easy to handle, cheap and ultimately available in many sizes to suit your needs. The capacity can vary from a few kilos to several tonnes. This enables the foundry to melt little batches cost-effectively, depending on the design. If production quantities are excessively boastfully, crucible furnaces may no longer be economically viable. This is due to the relatively gamey department of energy consumption ampere well as the ask manual labor of the employees, which mechanically causes high personnel costs.

We differentiate between used crucible furnaces according to their construction and heating form:

1. Movable and fixed crucibles
2. Resistance-heated and fuel-heated crucible furnaces
3. Tilting and fixed crucible furnaces
