Induction heating of aluminium billets using superconducting coils
Induction heating of aluminium and copper billets Induction heating is widely applied for heating of metals because it is a clean, fast and in most cases a very energy-efficient method. An alternating current is passed through the copper windings of a coil to generate a time-varying magnetic field. The field induces currents and thereby resistive losses in the workpiece to be heated, (see Fig. 1) Induction heating of aluminium billets
