To date, induction heating has only rarely been used for the re-heating of metals in mass production applications due to the low efficiency of energy transfer to the metals during the non-magnetic phase. The experience of Fives Celes in high-intensity magnetic fields generated by low-loss conductive composite multi-layer windings has enabled the development of a new high-flux magnetic induction technology (CELINE) which represents a real technological leap forward in respect to the current state-of-the-art.
In particular, the technology is characterized by:
Power density of 4 to 6 Mw/m², i.e.up to six times that of traditional inductors,
An electrical efficiency of 85% above the Curie-point, as opposed to the previous 50 to 60%, representing a considerable saving in electrical energy consumption,
A space requirement limited to approximately 1 m per MW injected in the typical case of a billet of 90 mm in diameter,
Thermal and mechanical protection devices designed to reduce maintenance costs when operating under extreme conditions.
The CELINE inductor suits particularly for re-heating round or square billets, tubes, thin slabs, etc. It may be used to treat all types of steel in the non-magnetic phase, copper or copper alloys, aluminum or aluminum alloys.
In the steel industry, for example, the CELINE inductor offers a modern and efficient method or re-heating before breaking-down or between the stands of the finishing line. It may be used as a "booster" for an existing furnace in order to increase production and optimize energy consumption.
