Abstract
An induction heating device for continuously moving metal strip (22) for heat treatment or coating purposes comprises a flattened, spirally wound coil having the turns interlinked by an oblique connection on a small side of the coil, and surrounding the continuously moving metal strip (22). Means (24-26) are provided for suppressing the transverse component of the magnetic field created by the said coil.
Claims8
A longitudinally extending inductor (3,4), for induction heating of continuously longitudinally moving metal strips (1,22,31) for heat-treatment or coating-treatment purposes, constituted by a coil in the form of a flattened helix, said coil comprising:
- a plurality of turns (11-13) connected together by oblique connections (14) arranged on a short side of the coil and surrounding each continuously moving metal strip (1,22,31);
- and means (24-26) for suppressing a transverse component of the magnetic field created by said coil.
