Products for the Steel 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.


  • Crucible Backing Material

    Dypack Backing Material

    Complimenting Dyson’s range of crucibles Dyson Technical Ceramics also offer thermal insulating Dypack™ backing material, which can be used in air and induction melting applications.  Also referred to as “Ramming Material” or “Crucible Back-up”, it creates a safety barrier in the unlikely event of a crucible failure.  The crucible back-up also insulates the crucible, helping reduce changes in temperature that can cause thermal stress.

  • 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
  • Sliding Gate plate InsertsZirconia Sliding Gate Plate Insert

    Sliding Gate Plate Inserts

    Dyson Technical Ceramics manufactures a range of high density zirconia sliding gate plate inserts, which are used within sliding gate plate applications. The inserts are generally used within a cast or pressed refractory plate.

    Sliding Gate Plate inserts are an excellent solution to increasing the life span of sliding gate plates. Once a sliding gate plate becomes worn,
    the worn material can be removed and a high density DysonTC Zirconia Plate insert can be cemented/cast in its place, therefore extending the life of the sliding gate plate.

  • Tundish Metering NozzlesTundish Metering Nozzles

    Tundish Metering Nozzles

    Dyson Technical Ceramics manufactures a comprehensive range of high performance Zirconia Tundish Metering Nozzles used mainly in the continuous casting of steel billets. Tundish Nozzles usually comprise a zirconia inner nozzle (often referred to as a “zirconia insert”) with a lower grade outer body such as Alumina, Zircon or Bauxite.
