La buse de coul\u00e9e comprend une entr\u00e9e \u00e9troite \u00e0 l'arri\u00e8re et une sortie plus large \u00e0 l'avant. Un bloc de s\u00e9paration est dispos\u00e9 dans le canal de mati\u00e8re, entre l'entr\u00e9e et la sortie, afin de diviser ce dernier en deux parties juxtapos\u00e9es. La partie arri\u00e8re du bloc de s\u00e9paration fait saillie vers l'arri\u00e8re \u00e0 partir de l'ouverture d'alimentation, et sa section transversale horizontale a la forme d'un arc de cercle. La partie centrale du bloc de s\u00e9paration est situ\u00e9e dans le canal de passage du mat\u00e9riau, et sa section transversale horizontale est triangulaire. La partie avant du bloc de s\u00e9paration s'\u00e9tend vers l'avant \u00e0 partir du canal de passage du mat\u00e9riau et d\u00e9passe de l'orifice de d\u00e9charge \u00e0 l'extr\u00e9mit\u00e9 avant ; sa section transversale horizontale est rectiligne.<\/p>\n

Un bloc de partition est dispos\u00e9 dans le buse de coul\u00e9e<\/a>, ce qui permet de produire simultan\u00e9ment deux billettes de coul\u00e9e et de laminage de faible largeur sur le m\u00eame \u00e9quipement de coul\u00e9e et de laminage, ce qui am\u00e9liore le taux d'utilisation de l'\u00e9quipement et r\u00e9duit les co\u00fbts de fabrication. Parall\u00e8lement, la forme du bloc de s\u00e9paration permet au mat\u00e9riau d'entrer en douceur dans le cylindre, ce qui garantit la fiabilit\u00e9 du processus de production.<\/p>\n

1. Fabriqu\u00e9 \u00e0 partir de mat\u00e9riaux composites fibreux \u00e0 l'\u00e9chelle nanom\u00e9trique, il pr\u00e9sente une distribution granulom\u00e9trique homog\u00e8ne, est produit \u00e0 l'aide d'\u00e9quipements de pr\u00e9cision et offre une densit\u00e9 et une rigidit\u00e9 appropri\u00e9es, ainsi qu'une taille stable.<\/p>\n

2. Un rev\u00eatement sp\u00e9cial est appliqu\u00e9 au pinceau sur les parties cl\u00e9s de la pointe de la roulette. Il pr\u00e9sente l'avantage de ne pas s'\u00e9cailler, d'emp\u00eacher l'aluminium fondu d'adh\u00e9rer et d'offrir une bonne r\u00e9sistance \u00e0 l'\u00e9rosion.<\/p>\n

3. La structure interne est con\u00e7ue avec un canal de coul\u00e9e raisonnable et sym\u00e9trique afin de r\u00e9pondre aux exigences en mati\u00e8re de dynamique des fluides de l'aluminium en fusion.<\/p>\n

4. Une bonne isolation thermique permettant de contr\u00f4ler efficacement la temp\u00e9rature constante pendant la coul\u00e9e de l'aluminium. C'est le meilleur choix pour la production de feuilles d'aluminium de haute qualit\u00e9.<\/p>\n

5.
