    A combination of excellent cosmetic appearance and dimensional accuracy promotes stable casting conditions. All our nozzles are available in a wide variety of bore sizes and are widely used in bottom pour ladle applications, where flow control is of paramount importance. Our efficient manufacturing techniques enable our clients to get the products they need, when they are needed.

  • Firebricks



    Incorporating low iron, pre-calcined dense grain materials, this product is formulated to provide high strength, high abrasion resistance, low porosity and high refractoriness combined with a high resistance to glass furnace carryover, vapours and solids.



    A dry pressed high strength abrasion resistant firebrick with good dimensional tolerance. SDR-F is a high performance firebrick which finds application where resistance to glass furnace carryover in solid or vapour forms is required.

    Applications of SDS-F and SDR-F Firebricks include:

    • Lower regenerator walls (Glass)
    • Upper wall back up (Glass)
    • Rider arches, were loading is not severe (Glass)
    • Flues
    • Furnace and kiln working linings
    • High temperature furnace safety linings (Steel and Non Ferrous)
    • Reduction cells in Aluminium industry
  • Alumina Crucibles, AZ76Magnesia Crucibles, Alumina Crucibles

    Alumina Crucibles

    Dyson Technical Ceramics™ Isostatically Pressed Alumina Crucibles offer resistance to high temperatures, while maintaining good erosion resistance. Dyson Technical Ceramics manufactures a range of crucibles based on Alumina.
