A method for the continuous production of a cellular ceramic or glass plate having asymmetric cells comprising thermally treating ceramic particles and a blowing agent in a foaming furnace (3) while conveying said ceramic particles and said blowing agent at a first speed thereby forming a cellular ceramic plate, and annealing said cellular ceramic plate in an annealing lehr (4) by cooling it down while conveying it at a second speed, larger than said first speed, thereby stretching and cooling said cellular ceramic or glass plate.
La présente invention concerne un procédé permettant la production en continu dune plaque de céramique alvéolée présentant des alvéoles asymétriques comprenant le traitement thermique de particules de céramique et dun agent dexpansion dans un four de moussage (3) en alimentant lesdites particules de céramique et lagent dexpansion à une première vitesse permettant ainsi la formation dune plaque de céramique alvéolée, et le recuit (4) de ladite plaque de céramique alvéolée dans une galerie de recuit par le refroidissement de la plaque en lalimentant à une seconde vitesse, supérieure à ladite première vitesse, entraînant ainsi lallongement et le refroidissement de ladite plaque de céramique alvéolée.
