The paper deals ìwith the induction heating of metal billets rotating in a DC magnetic field. 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. In the paper the induced power distributions are analysed and the main heating parameters are estimated with reference to an infinitely long aluminum billet 200 mm diameter. The paper refers to the activity developed in the frame of a NationalItalian Project carried out by research groups of the Universities of Bologna, Padua and Roma "La Sapienza". Other results obtained for the power distributions in finite length billets and the optimization of the exciting coils are presented in separate papers.

Abstract
The paper deals ìwith the induction heating of metal billets rotating in a DC magnetic field. 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. In the paper the induced power distributions are analysed and the main heating parameters are estimated with reference to an infinitely long aluminum billet 200 mm diameter. The paper refers to the activity developed in the frame of a NationalItalian Project carried out by research groups of the Universities of Bologna, Padua and Roma "La Sapienza". Other results obtained for the power distributions in finite length billets and the optimization of the exciting coils are presented in separate papers.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
