Induction heating of aluminium billets

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
