Coil arrangement for inductively heating metallic component, has coil made from wire and arranged in position relative to metallic component, where electric current flows via windings of coil in same direction during heating of component

摘要

The arrangement has a coil (22) made from wire i.e. copper wire, and arranged in a defined position relative to a metallic component (10), where electric current flows through windings (14) of the coil in same direction during heating of the component. The windings are arranged adjacent to areas (20) that are turned towards the component. Distance (d) between the windings is larger than radius of the wire. Magnetic field lines run in an area between the windings in an opposite direction.
