ABSTRACT:
Apparatus and method for transverse flux heating of metal strips, continuously moved in spaced proximity to induction heating inductor assemblies, comprised of conductors and flux guides; the conductors having relatively straight portions extending generally parallel to the strip surface and perpendicular to the length of the strip and curved or tapered portions, the curved portion of the conductors adapted to be positioned adjacent to the edges of the strip to control the current distribution within the strip and to maintain a uniform temperture distribution across the strip to avoid distortion of the strip and thereby allowing the use of high power densities. The inductor assemblies may be adjustable and if adjustable, may be adjusted to evenly heat strips of variable width and thickness.
