1. A method of at least partially curing a coating onto an electrically conductive cylindrical workpiece by induction heating comprising the steps of:

  • (a) generating a magnetic field oscillating at a frequency of approximately 500 Hz to 50 kHz along a heating path;

    (b) transporting the workpiece through the magnetic field generated in said step (a) along the heating path;

    (c) at least partially curing the coating onto the workpiece around a 360°

    circumference of the workpiece during said step (b) of transporting the workpiece through the magnetic field.
