<p>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 DEG C to 950 DEG 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 DEG C to 634 DEG 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 DEG C to 140 DEG C with an average cooling rate ranging from 0.016 to 0.020 degrees/sec. <IMAGE></p> |
