Abstract

Procédé et installation de réalisation d'empreintes sur des tubes en céramique poreuse. Method and installation for making fingerprints on porous ceramic tubes.

Immédiatement après le formage desdits tubes, on déforme la paroi externe de ceux-ci pour réaliser des empreintes dans la paroi interne, à l'aide d'outils. On déplace lesdits outils de telle façon que la vitesse relative des ces outils par rapport à la vitesse de sortie de tube soit sensiblement nulle au moment de la réalisation de l'em­ preinte, afin de minimiser les contraintes. Ensuite, on coupe le tube pour obtenir des portions de tube de longueur désirée et munies d'empreintes. Immediately after the said tubes are formed, deforms the outer wall thereof to produce footprints in the inner wall, using tools. We move said tools in such a way that the relative speed of these tools relative to the tube outlet speed be substantially zero at the time of the em preinte, in order to minimize the constraints. Then we cut the tube to get length tube portions desired and fitted with fingerprints.

Application à la réalisation du tube en céramique destiné à définir des tubes poreux pour la diffusion gazeuse. Application to the production of the ceramic tube intended to define porous tubes for gas diffusion.
