Supercera Ceramic Fibre

Boards & Blocks
Supercera Boards and Blocks are made from superspun Supercera fibres by multi component organic / inorganic bonding process.

Supercera Blocks and shapes are obtained by vacuum suction of a mixture of Supercera ceramic fibres with organic and mineral binders. These vacuum formed products can be moulded and cured into a wide variety of shapes to have a smooth inside surface and a rougher outside, as demanded by the application.

Supercera Fibre Boards, Blocks and shapes can be rendered machinable- to be sawed, drilled or machined, when required.

Application (Vacuum Formed Shapes)

  • Combustion Chambers
  • Domestic boiler doors
  • Peep holes, Pipe Seals
  • Special furnace lining parts
  • Radiant element supports in vitroceramic hotplates (Either electric resistance or halogen)

 

Application (Boards and Blocks)

  • Lining of : Furnaces including electric Furances; Flue and chimney of furnace and kilns; Hot gas ducts; combustion chamber in central heating boiler;
  • Glass tank side, ends walls, and port neck, low and high temperature driers.
  • Trough and distribution lining for conveying molten metal
  • Refractory backup for bricks and castables.
  • Pouring forms for non ferrous castings
  • High temperature baffles and muffles
  • Heat shield for personnel protection
  • Rigid high temperature gaskets and seals
  • Expansion joints.

Supercera Anchored Modules and Veneereing Modules


Anchored Modules are made from folds of Supercera Ceramic fibre - the only superspun double-needled fibre in the country. The module is held in compression by removable strapping. Each module has an integral anchoring system- the result of continuous R & D and advanced design.

Fixing of the module to metal shell is achieved by welding specially designed studs, supplied integral with the module, resulting in efficient, fast and error free installation,

Advantages

  • Fast and efficient installation
  • Lesser down time
  • No gap between the casing plate and the module
  • Faster cycling with increased plant utilization
  • Higher fuel economy
  • Lower installed cost
  • Lower maintenance cost

 

Application

  • Reheating furnaces
  • Bell Annealing Furnaces
  • Soaking pit seals and covers
  • Laddle Preheaters
  • Chemical precoess Heaters
  • Kilns
  • Incinertors
  • Reformers, etc.

Speciality Products


A. Supercera Cermic Fibre Cloth/ Tape


Supercera cloth/ tape is a high temp. specially fabric used for variety of industrial applications. It contains 15-20% organic carrier fiber to facilitate the carding process, which may burn off at a lower temperature. This however does not change the mechanical features including strength. It exhibits excellent chemical stability, resistance attack from most corrosive agents. Available in standard thickness of 3mm. Other thicknesses available on request.

Technical Details
Size / Packing
Cloth: 3mm x 300mm x 10RMT
Tape: 3mm x 50mm x 25 RMT

B. Supercera Twisted Rope/ Braids


Supercera Twisted Rope is a three-ply rope manufactured from supercera long fibres. It contains 15-20% organic carrier fibre to facilities the carding process which may burn off at a lower temperature.

Supercera Twisted Rope is a dense, resilient high temperature refractory possessing excellent thermal properties, chemical stability and high mechanical strength.

Supercera Braids: Supercera Braided Rope is available with SS 304/ SS 310 Braiding.
