Device for inductive heating of metal sheets, has inductor comprising two feed lines connected with outer and inner ends of induction coil, respectively, where coil runs in one plane and one of feed lines is aligned vertical to plane

摘要

The device has an inductor comprising a first feed line and a second feed line (11) connected with outer and inner ends (7, 9) of an induction coil (1), respectively. The coil runs in one plane, and the second feed line is aligned vertical to the plane. The coil is formed by a conductor (3) that extends along windings (5). The inner end is arranged in a region of a central recess (15) in which windings are not arranged. Distance between opposite portions of the conductor is larger than distance between adjacent portions of the conductor in a region radially outside of the central recess.
