A device for the induction heating of a billet of metal of high electrical conductivity comprising: a tubular body (4) supporting a plurality of permanent magnets (7p and 7n) arranged inside the tubular body, angularly spaced apart from each other and arranged so as to be alternated with opposite polarities; a support (8) for the billet (2) that is arranged inside the tubular body and faces said magnets; , a motor (10) adapted to rotate the tubular body with respect to the billet in order to induce currents in the billet that circulate within the metal material, obtaining the heating of the billet by the Joule effect. An integral cooling system (13) for the permanent magnets (7p and 7n) is provided, this being carried by the tubular body (4) and suitable for feeding cooling air flows between adjacent permanent magnets (7p and 7n).

Abstract

A device for the induction heating of a billet of metal of high electrical conductivity comprising: a tubular body (4) supporting a plurality of permanent magnets (7p and 7n) arranged inside the tubular body, angularly spaced apart from each other and arranged so as to be alternated with opposite polarities; a support (8) for the billet (2) that is arranged inside the tubular body and faces said magnets; , a motor (10) adapted to rotate the tubular body with respect to the billet in order to induce currents in the billet that circulate within the metal material, obtaining the heating of the billet by the Joule effect. An integral cooling system (13) for the permanent magnets (7p and 7n) is provided, this being carried by the tubular body (4) and suitable for feeding cooling air flows between adjacent permanent magnets (7p and 7n).
