Lime bound silica bricks with a SiO2 content of ≥ 95 % are manufactured from selected pure, well washed, crushed and carefully mixed quartz raw materials. These materials are obtained mainly from our own quarzite deposits.
The operating equipment and the operating procedures guarantee manufacture of silica bricks with excellent stability, defined mineralogical composition and high stability under high temperature and pressure stresses. The main areas of use for silica bricks are coke oven plants (oven floor, heating wall, oven roof and the upper regeneration layers), the superstructure of glass melters (and where required also in the upper structure of the re-generator) and in the high temperature areas of hot blast stoves.
High silicon oxide content | Acid erosion resistance | No shrinking in reheating | High grade refractoriness
