Tank block


For furnace bottoms of glass melting furnaces and parts of the tank block that come into contact with glass, it is common to use AZS fused cast refractories or alpha/beta alumina fused cast refractories. For furnaces with increased thermal insulation, molten glass penetrates through joints in the fused cast refractories. Furnace bottoms and lined bricks of tank blocks come into contact with glass that flows in through the joints. Refractories used in these situations must have high corrosion and pollution resistance against molten glass. Most suitable is tank block that is carefully-selected clay-type materials, produced under appropriate condition. Tank block is produced in a large mold to prevent further molten glass penetration.

Super duty chamotte bricks


This fireclay brick uses special ingredients which is formed at high pressure and fully sintered, so that it has very low porosity and is highly heat-resistant. It is also highly alkali resistant and creep resistant. It is particularly suitable for the lower parts of regenerator checkers, rider arch and middle and lower parts of regenerators walls.


This product is fireclay brick that is dense and highly alkali-resistant. It is suitable for lower parts of regenerator walls.
