Extrusion Equipment 027 EE Rebuilding a 200 kW Rotating Billet Superconducting Induction Heater Niklas Magnusson, Magne Runde -- SINTEF Energy Research, Norway; Stefan Dappen -- SMS Elotherm, Germany; Artur Dobosz -- Grupa Kety SA, Poland; Peter Blau -- Fraunhofer Gesellschaft, Germany; Giovanni Grasso -- Columbus Superconductors, Italy Risto Mikkonen -- Tampere University of Technology, Finland; Zdenek Jelinek -- Skoda Vyzkum, Czech Republic ; Bernard Nacke -- University of Hannover, Germany; Tomasz Stuczynski -- Institute of Non-Ferrous Metals, Poland A new-concept 200kW induction heater is a joint European project between four companies, three research institutes and two universities. Aluminum billet is rotated in a direct-current (DC) magnetic field, while superconducting coils are cooled. The magnetic field is generated in low-cost MgB2 superconductor wires. Benefits are discussed, comparing the rotating billet heater to conventional induction heaters, highlighting reduced energy losses, and reduced lifetime costs. |
