Definitions

  • a particularly advantageous embodiment of the invention in practice is characterized in that it is equipped with at least two inductively operating heating devices arranged in pairs. Such a paired arrangement makes it possible, on the one hand, to introduce increased amounts of heat into the rolling stock. At the same time, by adjusting the inductors accordingly, the transverse field generated by them can be designed such that it always reliably detects the strip to be heated over its full width.
  • SI / cs 030 3 4 2 WO cast metal strip and a device arranged between the device for casting and the device for hot rolling, designed according to the invention for reheating the cast tape before hot rolling.
  • SI / cs 03034 2 O non-conductive material to avoid undesirable current flows due to the electromagnetic fields generated by the inductors 14-17a.
  • the heating devices 10, 11, 12, 13 of the device 7 are arranged in succession in the conveying direction F alternately on the side of one side 18a and the other side 18b of the conveying path 18, so that one with respect to FIG the band 3 to be heated has a symmetrical design and effect of the individual fields generated by the inductors 14-17a.

Abstract

L'invention concerne un dispositif qui permet de chauffer une bande métallique (3), pour la porter à une température prédéterminée de manière précise et rapide, avec un encombrement réduit. Cette invention concerne également une installation conçue pour produire des bandes métalliques laminées à chaud, qui permet de chauffer des articles à laminer d'une manière optimale pour le laminage, malgré le faible espace de montage disponible. A cet effet, le dispositif selon l'invention est équipé d'au moins un système de chauffage à fonctionnement inductif (10, 11, 12, 13) pourvu d'un inducteur (14, 15, 16, 17) qui induit un champ électromagnétique, s'étend sur la section de transport (F) de la bande métallique (3) à chauffer et dont la position peut être réglée transversalement à la section de transport, en fonction de la largeur de la bande métallique.
