Explanation of a Coreless Induction Furnace – Furnace Cooling

As seen in channel furnaces a stirring occurs. This stirring allows for molten metal to rise upwards. Slag forms along the top and middle layers of the crucible. This differs from the slag build up found in channel furnaces. Channel furnaces form slag in the throat of the furnace above the induction unit.

MELTING EFFICIENCY - F2A

The gradual slag build up increases the furnace wall's thickness (through which heat is transferred to the metal) which can greatly reduce the furnace's overall electrical efficiency and capacity. For example, in a 5 tonne coreless induction furnace a slag build-up to an overall thickness of 15.5 cm reduces the furnace capacity to 4.5 tonnes.3

Refractory failure in induction furnaces can be limited ...

Jun 01, 1991· The deposits entrap metal that superheats, causing penetration and even refractory melting. Coreless furnaces can build up in the midcoil area to the extent that the entire lower crucible becomes bridged. A similar scenario results in channel furnaces when the throat becomes clogged, bridging the inductor to the body of the furnace.
