Abstract
In the induction heating of rotationally symmetrical workpieces, the workpieces are passed through the treatment region with magnetic flux in the region parallel to the axis of symmetry of each workpiece as it passes through the treatment region. In order to obtain uniform heating of the workpieces, flux modifying members are provided which are arranged so that the resultant distribution, across the workpiece transversely of the axis thereof of the magnetic flux density in the axial direction is substantially inversely related to the distance from the axis of rotational symmetry of the workpiece.
