A METHOD FOR A CONTINUOUS PRODUCTION OF DECORATIVE AND FACING SLABS AND A PLANT FOR REALIZING THE SAME, A DECORATIVE AND FACING MATERIAL

摘要

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 900-950 DEGREE 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 600-634 DEGREE 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 100-140 DEGREE C with an average cooling rate ranging from 0.016-0.020 degrees/sec.
