The invention relates to the production of decorative facing materials using a glass-pelletizer and refractory filler. The inventive method for a continuous production of decorative facing slabs consists in loading of basic materials into casting-moulds which are placed on an open heat-insulated palette, and in thermal treatment in a furnace at a temperature ranging from 900 ~C to 950 ~C. After the thermal treatment, the palette with the moulds is taken out and conditioned at an ambient temperature during 80-90 sec accompanied by cooling the surface of the slabs to a temperature ranging from 600 ~C to 634 ~C. Afterwards, the slabs are placed in a heat-insulated closed space having a thermal resistance of walls which makes it possible to cool the surface of the slab to a temperature ranging from 100 ~C to 140 ~C with an average cooling rate ranging from 0.016 to 0.020 degrees/sec.
L'invention relève de la fabrication des matériaux de revêtement de décoration sur la base de granulés de verre et d'une charge ignifuge. Le procédé de fabrication en continu de panneaux de revêtement de décoration consiste à charger les composants de base dans des formes que l'on place à l'intérieur d'un support ouvert thermiquement isolé puis à les traiter thermiquement au four à une température entre 900-950 ·C. Après le traitement thermique, le support avec les formes est poussé hors du four et laissé à température ambiante pendant 80 à 90 secondes, les surfaces frontales des plaques se refroidissant jusqu'à 600-634 ·C. Les plaques sont ensuite placées dans un espace clos thermiquement isolé dont la résistance thermique des murs assure le refroidissement des surfaces frontales des plaques jusqu'à 100-140 ·C, avec une vitesse de refroidissement moyenne entre 0,016 et 0,020 degrés/seconde.
