  • Induction heating apparatus
    Patent number: 6730893
    Abstract: Apparatus for induction heating of billet-shaped blanks (10) of electrically well conductive and non-magnetic metal, in particular aluminum or copper, comprising a winding (21) adapted to surround the blank completely or partially, to be supplied with electric alternating current (8) and to be cooled (22) at least during the heating of the blank (10). The winding has turns comprising superconducting material and is enclosed by a thermally insulating chamber (33). The cooling (22) is adapted to maintain the winding at a temperature in the range 30-90° K, and the frequency of the alternating current (8) is adapted to be in the range of common mains frequencies.
