Melting & Crucibles

Melting furnaces used in the foundry are of many various types. The selection is one of the most important decisions a foundry has to take.

Crucible Furnaces

The furnaces use a refractory crucible which contains the metal charge. The charge is heated via conduction of heat through the walls of the crucible. The heating fuel is typically coke, oil, gas or electricity. Crucible melting is commonly used where small batches of low melting point alloy are required. The capital outlay of these furnaces makes them attractive to small non-ferrous foundries.

  1. Tilting furnace, in which the molten metal is transferred to the mould or ladle by mechanically tilting the crucible and furnace body.
  2. Lift-out furnace, in which the crucible and molten metal are removed from the furnace body for direct pouring into the mould.
  3. Bale-out furnace, in which the metal is ladled from the crucible to the mould.

Induction Furnaces

The principle of induction melting is that a high voltage electrical source from a primary coil induces a low voltage, high current in the metal, or secondary coil. Induction heating is simply a method of transferring heat energy.

Electric Arc Furnaces

1. Direct arc furnaces
2. Indirect arc furnaces
Electric arc furnaces may be categorized as a direct arc or indirect arc. Both types of units are suited for the melting of high melting point alloys such as steels. They may be lined with acid or basic refractories.
