buse d'alimentation<\/a> est essentiel pour assurer la stabilit\u00e9 du processus de coul\u00e9e-laminage et am\u00e9liorer la qualit\u00e9 des t\u00f4les coul\u00e9es-lamin\u00e9es. Le r\u00f4le des joints internes est de rendre aussi uniformes que possible le champ de temp\u00e9rature et le champ d'\u00e9coulement du m\u00e9tal au niveau de la buse d'alimentation. La taille, l'espacement et le nombre de joints sont d\u00e9termin\u00e9s en fonction de la structure et de la largeur de la buse.<\/p>\nFabrication de l'ailette d'embouchure. \u00c9tant donn\u00e9 que le m\u00e9tal solidifi\u00e9 pr\u00e9sentera une certaine largeur apr\u00e8s laminage, en fonction du chanfreinage des rebords et de la composition de l'alliage, la largeur de l'ailette d'embouchure usin\u00e9e doit \u00eatre inf\u00e9rieure de 5 \u00e0 100 mm \u00e0 la largeur requise de la t\u00f4le. Les faces d'extr\u00e9mit\u00e9 situ\u00e9es de part et d'autre de l'\u00e9vent usin\u00e9 doivent \u00eatre perpendiculaires \u00e0 la face d'extr\u00e9mit\u00e9 inf\u00e9rieure, et les faces d'extr\u00e9mit\u00e9 des deux c\u00f4t\u00e9s doivent \u00eatre \u00e0 fleur afin de garantir l'absence d'espace entre les rebords lat\u00e9raux.<\/p>\n
L'\u00e9paisseur du bord avant de l'\u00e9vent de la bouche varie g\u00e9n\u00e9ralement en fonction du mat\u00e9riau et de la r\u00e9sistance de celui-ci. La d\u00e9termination de l'\u00e9paisseur du bord avant de la buse doit \u00eatre prise en compte de mani\u00e8re globale, en tenant compte de l'alliage, de l'\u00e9paisseur de la t\u00f4le et de la force de laminage dans la zone de coul\u00e9e et de laminage. L'\u00e9paisseur du bord avant de la buse est g\u00e9n\u00e9ralement comprise entre 2,5 et 5 mm.<\/p>","protected":false},"excerpt":{"rendered":"
