Definitions

  • FIG. 9 is an isometric view of another example of a fixed powered coil section used in the present invention.
  • one or more cooling passages may be provided within the coil section or external to the coil section, for example, by at least partially surrounding the coil section with a tubular material providing the cooling passages.
  • a cooling medium such as water, may be supplied through the cooling passages.
  • the moveable passive coil section may be formed as a single turn coil, as shown in FIG. 2, or as a multi-turn coil that is used in combination with a single or multi-turn fixed powered coil section.
  • coil sections 14 can be moved (slid) in a direction (Y-direction) transverse to the edges of the workpiece to accommodate workpieces of different widths; to alter edge heating patterns of the workpiece; or to have the width of the upper and lower coil assemblies track the edges of a workpiece moving in a direction (weaving in the Y-direction) perpendicular to the movement of the workpiece between the upper and lower induction coil.
  • Movement of a moveable passive coil section is similar to that of a drawer in an enclosure where the drawer is the moveable passive coil section, and the volume defined by the interior of bridge 12a and riser 12c sections is the enclosure.
