Abstract

La présente invention concerne un bouchon ou une brique (1) pour l'injection de gaz dans du métal en fusion au travers d'une surface de contact avec le métal en fusion (11), comprenant (i) un corps réfractaire poreux (2) sensiblement entouré d'un corps sensiblement non poreux (9) à l'exception de la surface de contact avec le métal en fusion (11); et (ii) des organes conduisant les gaz (3, 5) servant à amener le gaz d'une source de gaz au corps poreux (2). Le bouchon ou la brique sont caractérisés en ce que le corps non poreux (11) est fait d'un matériau réfractaire, et que les corps poreux et non poreux (2, 11) ont été comprimés ensemble. Ce bouchon ou cette brique conviennent particulièrement pour l'injection puissante et fiable de petites bulles dans le bain de métal en fusion.

Claims (10)

  1. Bloc ou brique (1) réfractaire poreux solide pour un revêtement de récipient pour injecter un gaz dans un métal fondu à travers une surface (11) de contact d'un métal fondu comprenant:
    i) un corps (2) réfractaire poreux substantiellement entouré par un corps (9) substantiellement non-poreux, sauf à la surface de contact (11) du métal fondu; et
    ii) des moyens d'amenée du gaz (3,5) pour conduire le gaz depuis une source de gaz vers le corps poreux (2),
    caractérisé en ce que le corps non-poreux (11) est formé d'un matériau réfractaire et en ce que les corps poreux et non poreux (2,11) ont été copressés.
  2. Bloc ou brique selon la revendication 1 caractérisé en ce que les moyens d'amenée du gaz (3,5) comprennent une chambre (3).
  3. Bloc ou brique selon la revendication 1 ou 2, caractérisé en ce que les corps poreux et non-poreux sont constitués de matériaux réfractaires avec des coefficients de dilatation similaires.
  4. Bloc ou brique selon l'une quelconque des revendications 1 à 3, caractérisé en ce que les corps poreux et non-poreux sont constitués de plus de 50% en poids de magnésie, de magnésie spinelle, d'alumine ou d'alumine spinelle, de préférence de plus de 80% en poids.
  5. Bloc ou brique selon l'une quelconque des revendications 1 à 4, caractérisé en ce que le corps non-poreux comprend plus de 50% en poids, de préférence plus de 80% en poids, de magnésie, de magnésie spinelle, d'alumine ou d'alumine spinelle.
  6. Bloc ou brique selon l'une quelconque des revendications 1 à 5, caractérisé en ce que le corps poreux (2) possède une section (7) effilée vers la surface de contact du métal fondu.
  7. Procédé pour la fabrication d'un bloc ou brique poreux réfractaire solide pour un revêtement de récipient pour injecter du gaz dans un métal fondu à travers une surface de contact du métal fondu les étapes de :
    1) introduction de quantités appropriées de matériaux réfractaires constituant les corps poreux et non-poreux tout en respectant les limites désirées pour ces corps;
    2) copressage simultané des deux matériaux réfractaires;
    3) fourniture des moyens d'amenée de gaz;
    4) traitement thermique des matériaux copressés.
  8. Procédé selon la revendication 7, dans lequel les moyens d'amenée de gaz comprennent une chambre.
  9. Procédé selon la revendication 8, caractérisé en ce que l'étape (3) de fourniture des moyens d'amenée de gaz comprend une étape d'introduction d'une bandelette d'un matériau consommable dans le moule à la jonction entre les corps poreux et non-poreux.
  10. Procédé selon la revendication 9, caractérisé en ce que le matériau consommable comprend de la cire.
