Estimating the term…
Device for the electromagnetic induction heating of a metal strip travelling in a specified direction comprising at least one electric coil arranged opposite at least one of the large faces of the said strip so as to heat the latter by transverse magnetic flux induction, each coil being associated with at least one magnetic circuit, each circuit being divided into a plurality of mutually uncoupled magnetic bars arranged parallel to the direction of travel of the strip, the said magnetic circuit, consisting of the said plurality of mutually independent bars, adapts to the width of the strip to be heated by moving the said bars away from or towards one another, in such a way as to continuously adapt the distribution of the said magnetic flux to the characteristic dimensions of the said strip.
