Claims (6)

1. Устройство нагрева с помощью электромагнитной индукции металлической полосы (4), перемещающейся в определенном направлении, содержащее, по меньшей мере, одну электрическую катушку (2), расположенную напротив, по меньшей мере, одной из больших наружных поверхностей полосы так, чтобы нагревать последнюю путем индуктирования поперечного магнитного потока, причем каждая катушка связана, по меньшей мере, с одной магнитной цепью (6), при этом каждая цепь разделена на множество взаимно не связанных магнитных стержней (8), расположенных параллельно направлению перемещения полосы, отличающееся тем, что магнитная цепь (6), состоящая из множества взаимно независимых стержней (8), адаптируется к ширине нагреваемой полосы (4) путем перемещения стержней в направлении друг от друга или друг к другу таким образом, чтобы непрерывно адаптировать распределение магнитного потока к характерным размерам полосы.1. A heating device using electromagnetic induction of a metal strip (4) moving in a certain direction, containing at least one electric coil (2) located opposite at least one of the large outer surfaces of the strip so as to heat the latter by inducing a transverse magnetic flux, with each coil connected to at least one magnetic circuit (6), each circuit being divided into a plurality of mutually unconnected magnetic rods (8) arranged parallel about the direction of movement of the strip, characterized in that the magnetic circuit (6), consisting of many mutually independent rods (8), adapts to the width of the heated strip (4) by moving the rods in the direction from each other or to each other so that continuously adapt the magnetic flux distribution to the characteristic size of the strip. 2. Устройство нагрева по п. 1, отличающееся тем, что содержит экраны (14) с хорошей электропроводностью, расположенные в зазоре, образованном магнитными цепями, с обеих сторон полосы и вблизи краев полосы так, чтобы регулировать магнитный поток на концах полосы в направлении ее ширины. 2. The heating device according to claim 1, characterized in that it contains screens (14) with good electrical conductivity located in the gap formed by magnetic circuits on both sides of the strip and near the edges of the strip so as to regulate the magnetic flux at the ends of the strip in the direction of it width. 3. Устройство нагрева по одному из п. 1 или 2, отличающееся тем, что содержит магнитные накладки (16), расположенные в зазоре, образованном магнитными цепями, с обеих сторон полосы и вблизи краев полосы таким образом, чтобы оптимизировать распределение магнитного потока. 3.

Устройство нагрева по любому одному из предыдущих пунктов, отличающееся тем, что поверхность магнитной цепи (6) каждого якоря (1, 1'), которая находится напротив одной из больших наружных поверхностей полосы, имеет "полярный" профиль, адаптированный так, чтобы получить регулируемое распределение магнитного потока. 5. The heating device according to any one of the preceding paragraphs, characterized in that the surface of the magnetic circuit (6) of each armature (1, 1 '), which is opposite one of the large outer surfaces of the strip, has a "polar" profile, adapted so that get an adjustable magnetic flux distribution. 6. Устройство нагрева по любому одному из предыдущих пунктов, отличающееся тем, что содержит, по меньшей мере, один коротко-замкнутый виток, расположенный на любой стороне якоря (1, 1') таким образом, чтобы охватывать полосу (4) так, чтобы уменьшить рассеяние магнитных полей на концах индуктора. 6. The heating device according to any one of the preceding paragraphs, characterized in that it contains at least one short-closed coil located on either side of the armature (1, 1 ') so as to cover the strip (4) so that reduce the scattering of magnetic fields at the ends of the inductor.
