Dyson Technical Ceramics™ produces a range of products for Foundries. These include:
Pressed Foundry Ladle Nozzles
Composite Nozzles – Comprising of a high density Zirconia insert and an Alumina or Zircon outer body.
DysonTC™ possesses extensive R&D facilities, based in Sheffield, giving us the ability to develop materials to better suit your production processes.
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.
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.
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)
- Furnace and kiln working linings
- High temperature furnace safety linings (Steel and Non Ferrous)
- Reduction cells in Aluminium industry
Foundry Ladle Nozzles
Dyson Technical Ceramics™ Foundry Ladle Nozzles are available in a range of Alumina grade material qualities to suit casting requirements. Our nozzles are made from high purity raw materials to promote higher erosion resistance to metals and alloys.
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.
Dyson Technical Ceramics supplies a wide range of dimensionally accurate Holloware for use in the Steel and Steel Foundry Industries. For more details please see below.
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 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.

Zirconia Ceramic Filters
Dyson Technical Ceramics™ Zirconia Ceramics Filters are used in the filtration of Steel and Nickel/Cobalt based superalloy castings. DysonTC’s Zirconia Ceramic Filters offer resistance to high temperatures, while maintaining excellent erosion resistance. The fine textures of the filters provide excellent filtration properties, giving the caster cleaner melts and reducing the need for grinding/machining. Advanced production techniques help to give the filters an even 3D lattice, resulting in a smooth, non-turbulent melt flow.
