The invention concerns a method for producing metal strip (1) in an installation (2), in which a metal strand, especially a thin slab, is brought to a desired temperature and/or is maintained at a desired temperature in a furnace (3, 3a, 3b) and is subjected to a rolling process in a rolling train (4) downstream of the furnace (3, 3a, 3b) in the direction of conveyance (R) of the metal strand (1). In accordance with the invention, to prevent the formation of scale deposits in the downstream region of the furnace, provision is made for the metal strand (1) to be subjected to at least one descaling operation during its residence time in the region (5) of the furnace (3, 3a, 3b). In addition, the invention concerns an installation for producing metal strip.

L'invention concerne un procédé pour produire des bandes de métal (1) dans un dispositif (2), dans lequel une bande de métal, en particulier une brame mince, est portée à une température souhaitée dans un four (3, 3a, 3b) et/ ou est maintenue à une température souhaitée, puis elle est soumise à l'arrière du four (3, 3a, 3b), dans le sens du transport (R) de la bande de métal (1), à un processus de laminage dans un train de laminoir (4). L'objectif de l'invention est d'éliminer des dépôts de calamine à l'arrière du four. A cet effet, la bande de métal (1) est soumise pendant son passage dans la partie (5) du four (3, 3a, 3b) à au moins une opération de décalaminage.
