Abstract

Trempe d'article en verre par immersion dans une couche fluidisée. On maintient la couche fluidisée dans un état calme d'expansion uniforme en établissant, à la traversée de la membrane 2 à travers laquelle le gaz fludisant arrive dans la couche 16, une forte perte de charge, représentant au moins 60 % de la pression sous laquelle le gaz fluidisant arrive sous la membrane. Application en particulier à la trempe de feuilles de verre.
