Conventional induction heating of aluminium billets is a widely used technique in industry. However it is characterized by a very poor energy efficiency. Using a novel electromagnetic set-up where the aluminium billet rotates in a transverse DC magnetic field produced by superconducting coils, the energy efficiency increases to interesting values. The paper studies the induction heating of aluminium billets in this new set-up. The analytical electromagnetic problem is revised in an original form, the heating transient is studied numerically and relevant parameters are estimated.

Abstract
Conventional induction heating of aluminium billets is a widely used technique in industry. However it is characterized by a very poor energy efficiency. Using a novel electromagnetic set-up where the aluminium billet rotates in a transverse DC magnetic field produced by superconducting coils, the energy efficiency increases to interesting values. The paper studies the induction heating of aluminium billets in this new set-up. The analytical electromagnetic problem is revised in an original form, the heating transient is studied numerically and relevant parameters are estimated.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
