Abstract

L'invention concerne un procédé permettant de modifier l'épaisseur (D1) d'une brame (1) c'est-à-dire de faire passer ladite brame d'une première épaisseur (D1) à une seconde épaisseur (D2) pendant la coulée en continu, cela au moyen d'une lingotière de coulée en continu (6) comportant au moins deux espaces vides (5), au niveau de premières parois latérales (8, 8') constituant des délimitations et déterminant la largeur de la brame (1), et au niveau d'au moins deux autres secondes parois latérales (10, 10') adjacentes aux premières parois latérales (8, 8') et définissant l'épaisseur (D1, D2) de la brame (1). La lingotière comporte également un guide de brame (13) soutenant la brame (1) coulée à la suite des secondes parois latérales (10, 10') et pouvant s'adapter aux différentes épaisseurs (D1, D2) de la brame (1). Selon ledit procédé, la coulée de la matière en fusion (2) dans la lingotière (6) est interrompue brièvement avec formation d'une extrémité intermédiaire (20), et un manchon (21) est placé à ladite extrémité intermédiaire (20) de la brame (1), l'extrémité (24) du manchon (21) opposée à la brame (1) correspondant à la seconde épaisseur (D2) de celle-ci. Au moins une des secondes parois latérales (10, 10') est réglée de façon à permettre l'obtention de la seconde épaisseur (D2), l'extrémité (24) du manchon (21) opposée étant réglée par extraction de la brame (1) à une certaine hauteur à l'intérieur de la lingotière (6), la coulée de la matière en fusion (2) est ensuite continuée et le guide de brame (13) est adapté à la seconde épaisseur (D2).
