Definitions

  • This provides a cast rolling mill which is capable of rolling cast thin slabs of comparatively large casting thickness by means of at least seven rolling stands and rolling passes, preferably eight rolling stands and corresponding rolling passes, without the need for inductive intermediate heating in both batch and continuous operation ,
  • a system is provided by the particularly high casting thickness, which can produce a wide range of steel grades to a thickness of the thin or ultra-thin strip of 0.8 mm, without the need to provide an inductive intermediate heating, especially in continuous operation.

Abstract

L'invention concerne une installation de coulée et de laminage (1) destinée à produire une bande mince ou ultramince à partir d'une brame mince coulée en acier dans le fonctionnement par lots ou continu, comprenant au moins une installation de coulée (2a, 2b) destinée à couler une brame mince avec une épaisseur de coulée de 90 mm à 150 mm, de préférence de 90 mm à 140 mm, de préférence encore de 100 mm à 130 mm, et une largeur de coulée d'au moins 600 mm, de préférence d'au moins 1000 mm, au moins un four continu (7a, 7b) agencé en aval de ladite installation de coulée (2a, 2b) ainsi qu'au moins 7, de préférence 8, cages de laminoir (9, 10, 14, 15, 16, 17, 18, 19, 20) agencées en aval du four continu (7a, 7b), ladite installation de coulée (2a, 2b) comprenant une coquille de coulée (3a, 3b) dont les grands côtés présentent une distance l'un par rapport à l'autre d'au moins 90 mm à 150 mm, de préférence de 90 mm à 140 mm, de préférence encore de 100 mm à 130 mm, et l'installation de coulée et de laminage (1) ne présentant aucun chauffage par induction destiné au rechauffage de la brame mince coulée et/ou de la bande laminée. L'invention concerne en outre un procédé destiné à produire une bande mince ou ultramince, de préférence au moyen d'une telle installation de coulée et de laminage (1), la brame mince et/ou la bande ne subissant aucun chauffage par induction pendant le procédé destiné à produire la bande mince ou ultramince.
