FIELD: metallurgy.
SUBSTANCE: sections of a coil project in transverse direction beyond opposite edges of slab. Magnetic flux concentrators are arranged around zones of sections of the coil, which are located under and above the slab. Magnetic flux concentrator is placed between each of two opposite projecting edges of sections of the coil to the slab edge areas. As per an alternative version, induction heating of only one slab edge is performed.
EFFECT: invention provides heating of only slab edges to a great degree without any uniform distribution throughout its width.
