laver<\/a>, le caisson avant et le dispositif de contr\u00f4le du niveau de liquide, la buse d'alimentation, le dispositif d'alimentation en fil d'aluminium-titane-bore, le dispositif d'affinage et de d\u00e9gazage situ\u00e9 \u00e0 l'ext\u00e9rieur du four, etc. \u00c9tant donn\u00e9 que la position de montage de la buse d\u2019alimentation influe directement sur sa dur\u00e9e de vie et sur la qualit\u00e9 de la billette coul\u00e9e-lamin\u00e9e, il est n\u00e9cessaire d\u2019installer un dispositif de r\u00e9glage de la buse d\u2019alimentation afin de garantir le respect des tol\u00e9rances entre celle-ci et le cylindre de coul\u00e9e.<\/p>\nSyst\u00e8me de coul\u00e9e utilis\u00e9 dans les laminoirs \u00e0 coul\u00e9e descendante. Le bac avant est mont\u00e9 sur le chariot. Un flotteur situ\u00e9 au-dessus du bac avant permet de contr\u00f4ler le niveau de la masse fondue. La structure de ce syst\u00e8me de coul\u00e9e est complexe. Sa fabrication, son montage, son r\u00e9glage et son fonctionnement sont assez difficiles.<\/p>\n
Le syst\u00e8me de coul\u00e9e utilis\u00e9 par le laminoir \u00e0 coul\u00e9e inclin\u00e9e et \u00e0 bandes int\u00e8gre le bac avant, le canal transversal et la buse d'alimentation sur la plaque de fond et les assemble en un ensemble unique, ce qui facilite l'utilisation du m\u00e9canisme de r\u00e9glage du syst\u00e8me de coul\u00e9e. Positionnement pr\u00e9cis de la buse d'alimentation.<\/p>\n
Structure du syst\u00e8me de coul\u00e9e utilis\u00e9 dans le laminoir \u00e0 coul\u00e9e horizontale de bandes. Il se compose principalement d\u2019une goulotte, d\u2019un bouchon en c\u00e9ramique, d\u2019un flotteur, d\u2019un tube vertical, d\u2019un bac avant et d\u2019une buse d\u2019alimentation. L\u2019ext\u00e9rieur de la goulotte est soud\u00e9 \u00e0 partir de t\u00f4les d\u2019acier, tandis que le rev\u00eatement int\u00e9rieur est en argile de silicate d\u2019aluminium ; l\u2019aluminium liquide est \u00e9galement contenu dans ce rev\u00eatement en argile de silicate d\u2019aluminium. Le tube vertical fabriqu\u00e9 se d\u00e9verse dans le bac avant ; son extr\u00e9mit\u00e9 inf\u00e9rieure est munie d\u2019un flotteur en argile de silicate d\u2019aluminium qui flotte \u00e0 la surface de l\u2019aluminium en fusion afin de contr\u00f4ler la hauteur de la surface du m\u00e9tal en fusion dans le bac avant. De plus, afin d\u2019injecter de l\u2019azote dans le bain d\u2019aluminium, deux bouchons en c\u00e9ramique poreux et perm\u00e9ables au gaz sont install\u00e9s au fond de la goulotte. L\u2019azote peut ainsi \u00eatre inject\u00e9 dans le bain d\u2019aluminium \u00e0 travers ces deux bouchons en c\u00e9ramique. Lors de l\u2019injection, en fonction de la consommation d\u2019azote, on choisit des bouchons en c\u00e9ramique de structures diff\u00e9rentes et on adopte les m\u00e9thodes d\u2019installation appropri\u00e9es.<\/p>","protected":false},"excerpt":{"rendered":"
