Abstract
An apparatus for heating an elongated workpiece having an elongated axis and moving along a heating path in a selected linear direction, the path having opposite sides defining a workpiece passage therebetween. This apparatus comprises a plurality of high permeability flux directing elements, each of the elements having a generally flat surface spaced from and generally parallel to the heating path, means for mounting the elements along at least one side of the path at selected, mutually spaced locations, separate coil means encircling each of said elements and alternating current power means for causing separate, spaced magnetic flux fields extending from said surfaces and into said passage in a direction generally perpendicular to said path.
