Abstract

a. Procédé de refroidissement d'articles en verre 25 par introduction dans un dit fluidisé de particules 24 dans des conditions thermiques favorables à un transfert de chaleur. b. Suivant l'invention, les particules fluidisées 24 consistent au moins en partie en un matériau qui peut subir une modification endothermique par chauffage à une température inférieure à celle du verre au moment où il pénètre dans le dit fluidisé. La modification endothermique peut consister en une perte de groupements hydroxyles et/ou d'eau. c. Le procédé convient notamment pour la trempe thermique de feuilles de verre minces, planes ou bombées.
