Le moulage pneumatique et le moulage par glissement d'air permettent de produire des lingots de haute qualit\u00e9 et constituent des m\u00e9thodes de formage de lingots de pointe. Cependant, cette m\u00e9thode de moulage est plus sensible aux variations de pression atmosph\u00e9rique ; celle-ci doit donc \u00eatre contr\u00f4l\u00e9e avec pr\u00e9cision, et elle impose des exigences plus \u00e9lev\u00e9es quant \u00e0 la qualit\u00e9 du gaz de moulage. Plus la teneur en eau est faible, mieux c'est. L'anneau en graphite poreux utilis\u00e9 s'use rapidement et est co\u00fbteux. De plus, cette technologie de coul\u00e9e est exigeante et difficile \u00e0 ma\u00eetriser.<\/p>\n

Le moulage pneumatique \u00e0 t\u00eate chaude consiste \u00e0 faire passer un gaz sous une certaine pression entre les capuchon sup\u00e9rieur chauffant<\/a> et le cristalliseur, et sa pression est exactement en \u00e9quilibre avec la pression statique de la masse fondue \u00e0 cet endroit, formant ainsi un espace d'air entre la masse fondue et la paroi du moule. La masse fondue utilise cet espace d\u2019air pour glisser vers le bas et se solidifier, ce qui r\u00e9duit consid\u00e9rablement la conduction thermique par contact du moule (refroidissement 1), rend la surface du lingot lisse, limite l\u2019\u00e9paisseur de la couche refroidie et am\u00e9liore \u00e9galement la structure cristalline interne.<\/p>\n

La diff\u00e9rence entre le \u00ab hot top \u00bb \u00e0 glissement d'air et le \u00ab hot top \u00bb \u00e0 pression d'air r\u00e9side dans le fait qu'un anneau en graphite microporeux est int\u00e9gr\u00e9 au moule ; l'huile et le gaz p\u00e9n\u00e8trent \u00e0 travers l'interstice de cet anneau pour former un espace d'air qui permet \u00e0 la masse fondue de glisser vers le bas, de se solidifier et de prendre forme, ce qui permet d'obtenir des lingots moul\u00e9s de haute qualit\u00e9.<\/p>\n

Avantages du moulage par glissement d'air<\/strong><\/p>\n

    \n
  1. La qualit\u00e9 de surface du lingot est excellente. \u00c0 mesure que le refroidissement primaire s'affaiblit et que le refroidissement secondaire s'intensifie, la cavit\u00e9 de la masse fondue s'aplatit, ce qui \u00e9limine pratiquement les conditions propices \u00e0 l'apparition de taches de s\u00e9gr\u00e9gation en surface. Comme il subsiste une calotte chaude au sommet du lingot, le risque de formation de couches est consid\u00e9rablement r\u00e9duit lorsque la vitesse de coul\u00e9e est augment\u00e9e. Gr\u00e2ce \u00e0 la couche de lubrification huile\/gaz pr\u00e9sente entre l'enveloppe du lingot et la paroi du moule, la tendance \u00e0 la formation de fissures et de rayures superficielles est \u00e9galement consid\u00e9rablement r\u00e9duite. Par cons\u00e9quent, la qualit\u00e9 de surface des lingots issus de la coul\u00e9e \u00e0 glissement d'air est sup\u00e9rieure \u00e0 celle des lingots issus de la coul\u00e9e \u00e0 t\u00eate chaude.<\/li>\n
  2. La tendance \u00e0 la fissuration des lingots est r\u00e9duite. La forme plus plate de la cavit\u00e9 de m\u00e9tal en fusion rend la r\u00e9partition des contraintes thermiques plus uniforme, ce qui r\u00e9duit la tendance \u00e0 la fissuration des lingots. Il est ainsi possible d'utiliser une vitesse de coul\u00e9e plus \u00e9lev\u00e9e, ce qui am\u00e9liore le rendement de production.<\/li>\n
  3. Les grains sont plus fins et plus uniformes. Une r\u00e9sistance au refroidissement plus \u00e9lev\u00e9e et une vitesse de coul\u00e9e plus rapide augmentent toutes deux la vitesse moyenne de cristallisation du lingot. Par cons\u00e9quent, la structure cristalline du lingot est plus fine et plus uniforme, ce qui am\u00e9liore les performances globales de l'ensemble du lingot.<\/li>\n
  4. L'intensit\u00e9 en main-d'\u0153uvre est faible.<\/li>\n<\/ol>","protected":false},"excerpt":{"rendered":"
