摘要： The present invention intends to reduce the unbalance among phase currents without the use of a Scott-connection transformer. The present invention is an induction heating system 100 adapted to use a three-phase AC power source 4 to operate a first induction heating apparatus 2 including a first induction coil 21 and a second induction heating apparatus 3 including a second induction coil 31. In addition, the number of turns of the second induction coil 31 is an even number. Also, one of the winding start point 21x and winding end point 21y of the first induction coil 21 is electrically connected to one phase of the three-phase AC power source 4, and the other one is electrically connected to the midpoint 31z of the second induction coil 31. Further, the winding start point 31x and winding end point 31y of the second induction coil 31 are electrically connected to the remaining two phases of the three-phase AC power source 4.

摘要： 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).
