Abstract (en)

[origin: EP0808079A1] An induction heating coil assembly for use in a roller induction heating line has a magnetic shunt (30) for receiving a portion of an electromagnetic field generated along the axis of the induction coil (28) and directing that portion along a path parallel to a workpiece (26) passing along the heating line. This flux path ensures that eddy currents induced in the workpiece (26) flow primarily perpendicular to the axis of the workpiece, and not along the axis of the workpiece where they could cause arcing between the moving workpiece and the conveyor rolls. <IMAGE>
