The paper aims to deal with the induction heating of metal billets rotating in a DC magnetic field. The induced power distributions are analyzed and the main heating parameters are estimated with reference to an infinitely long Al billet 200 mm diameter. The paper refers of the activity developed in the frame of a National Italian project carried out by research groups of the Universities of Bologna, Padua and Roma “La Sapienza”. The main process parameters have been evaluated for the heating up to 500°C of an Al billet 200 mm diameter. This innovative technology appears to be very promising for improving the efficiency of the through heating of high conductivity metals (e.g. copper, aluminum) before hot working, by using superconducting magnets.

Abstract
The paper aims to deal with the induction heating of metal billets rotating in a DC magnetic field. The induced power distributions are analyzed and the main heating parameters are estimated with reference to an infinitely long Al billet 200 mm diameter. The paper refers of the activity developed in the frame of a National Italian project carried out by research groups of the Universities of Bologna, Padua and Roma “La Sapienza”. The main process parameters have been evaluated for the heating up to 500°C of an Al billet 200 mm diameter. This innovative technology appears to be very promising for improving the efficiency of the through heating of high conductivity metals (e.g. copper, aluminum) before hot working, by using superconducting magnets.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
