Abstract

An inductor is provided for the simultaneous inductive heating of two tracks or ways which are formed next to one another on a metallic workpiece, having a first segment which is associated with the first track or way and a second segment which is associated with the second track or way, and having two supply arms via which the segments can be connected to a power supply. To enable two tracks or ways to be heated simultaneously to the hardening temperature without heating the material portion situated between the tracks or ways the segments of the inductor and the supply arms are connected together in an inductor in such a way that the fields travelling at right angles to the longitudinal extent of the tracks or ways neutralize each other in the region of the material portion which separates the tracks or ways from one another.
