Experience in the production of hot rolled steel strip has shown that it is very difficult to meet these requirements when using the two-roll casting process on a corresponding casting plant.
  • the metal strip is produced in a process of highest solidification speeds directly in a format with extreme width / thickness ratio, which accounts for a variety of rolling passes to achieve the desired hot strip final thickness, but on the other hand, a wide independent, uniform convective heat transfer or liquid metal temperature on the solidification front (in the formation of the strand shells) are only partially possible as a result of highly turbulent flow processes in the metal bath.

Abstract

L'invention concerne un procédé permettant de produire en continu une fine bande métallique, notamment un feuillard laminé à chaud, directement à partir de métal fondu et avec une épaisseur de coulée de bande < 10 mm après le procédé de coulée par rouleaux, la bande métallique coulée subissant ensuite une réduction d'épaisseur immédiate, puis étant acheminée jusqu'à un dispositif de stockage. L'invention vise, dans un processus de production continu, à obtenir, directement à partir du métal fondu et avec une épaisseur de coulée de bande réduite, une bande métallique laminée à chaud de haute qualité, avec des tolérances de planéité comparables à celles qui peuvent être obtenues lors de la production de bandes métalliques laminées à chaud à partir de brames minces ou de brames coulées en continu, avec des épaisseurs de coulée comprises entre 40 et 300 mm. A cet effet, il est prévu d'effectuer une mesure de planéité sur la bande métallique déplacée et d'utiliser les résultats de ces mesures de planéité pour influer de manière ciblée sur la planéité de la bande métallique.
