CERAMIC FIBRE PRODUCTS

 

SUPERCERA BULK FIBRE

Supercera is a high temperature insulating refractory fibre processed from high purity alumina and silica constituent specially selected for high strength refractoriness and stability even under severe conditions.

 

Supercera spun texture gives it the added extra of exceptionally long fibres and superior mechanical properties essential to meet rugged service conditions.

 

Supercera bulk fibers provide superior acoustical benefit in addition to high thermal performance a relevant benefit in process furnaces. Supercera can be handled and worked into expansion joints, wall penetrations and other areas with nominal skills. In specific cases, our application engineers would be happy to assist with Heat Loss. Surface Temperature and Heat Storage Computations.

 

APPLICATIONS:


As a resilient fill for packing material in high temperature areas like:

  Burner openings
Kiln Insulations
Furnace patch sealing
Emergency repairs in refractory
Glass Tanks and glass processing
Furnace repairs
  Expansion Joints
  Fibre Boxes

SUPERCERA BLANKETS

Supercera Blanket is a refractory fibre needled mat made without binder from Supercera fibres the only super-spun double needled fibre in the country today. Supercera RTZ and HTZ blankets zirconica stabilized and are suitable for use upto 1260°C and 1425°C respectively. Both blankets have excellent resistance to most chemicals. If wet by oil or water, their thermal and physical properties are fully restored upon drying. It is available in density of 64, 96 & 128 kg/m3. size 7620x610mm, thickness: 6,12, 20,25, 50 mm. They confirm to IS 15402 & ASTM C892.


APPLICATIONS:

  Annealing furnaces and glass kilns
Reformers & Ducts in petrochemical
Fertilizer and Boiler Linings Industry
High temperature pipe insulation
HRSG and stack linings
Glass Furnace crown insulation
  Trundish Cover, Transfer cars in steel plants
  Soaking pit seals and expansion joint
  Kilns, kiln cars for Ceramic industry
  Annealing cover bottom seals
  Reusable insulation blankets for filed stress relieving of welds
  Insulation blankets for steam and gas turbines and fire protection
  Insulation wrap on investment casting moulds
  Temporary repair of refractory furnace linings and roofs
  High temperature filter media / gaskets
  Furnace door seals, linings and gaskets
  High Temperature Sound Absorption and Nuclear Insulation applications


 

SUPERCERA BOARDS & BLOCKS

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

 

Supercera Blocks and Shapes are obtained by vacuum suction of a mixture of Supercera 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 are self supporting with excellent stability at high temperature, having high resistance to thermal sock and chemical attack. Supercera Fibre Boards, Blocks and Shapes can be rendered machinable – to be sawed, drilled or machined, where required. Density: 260-320, 720 kg/m3, size 915x600mm & 1000x500mm, thickness: 10-50m

.

APPLICATION:
(Vacuum Formed Shapes)

  Combustion chambers
Domestic boiled doors
Peep holes, Pipe seals
Special furnace Lining parts
Radiant element supports in vitroceramic hotplates (either electric resistance or halogen)

 

APPLICATIONS:
(Boards and Blocks)

  Lining of: Furnaces including electric furnaces; Flue and Chimney of furnaces and kilns; Hot gas ducts; Combustion chamber in central heating boiler; glass tank side, end walls and port neck; Low and high temperature driers
Trough and distribution linings for conveying molten metal
Refractory back up for bricks and castebles
Pouring forms for non ferrous castings
High temperature baffles and muffles
Heat shield for personnel protection
Rigid high temperature gasket and seals
Expansion joints
Boiler Tubes Insulation

 

 

SUPERCERA ANCHORED MODULES AND VENEERING MODULES

Supercera Anchored Modules are made form 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 designing. 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. Supercera Modules are ideal for full thickness lining for new furnaces as well as conversion into fibre lining in case of old furnaces. They enhance the furnace life and performance.

 

Supercera Veneered Modules improve the thermal efficiency of old brick linings with minimum downtime for repairs.

.

APPLICATIONS:

Reheating Furnaces
Bell Annealing Furnaces
Soaking Pit Seals and covers
Laddle Preheaters
Chemical Process Heaters
Incinerators
Reformers, etc.

 

 

SUPERCERA PAD CLOTH / TAPE, ROPE & PAPER

Supercera Cloth/Tape is a high temp. specially fabric used for a variety of Industrial applications. It contains 15-20% organic carrier fibre 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, resisting attack from most corrosive agents. Available in standard thickness of 3 mm; other thicknesses available at request.
Cloth Size: 3mm x 300mm / 1000mm x 10m

Tape Size: 3mm x 50mm x 25m

 

Supercera Pad is Supercera Blanket covered with Supercera cloth or glass cloth for insulation of turbines, valves & flanges. For external application, pads are coated with Teflon.

 

Supercera Twisted Rope is a three-ply rope manufactured from Supercera long fibres. It contains 15-20% organic carrier fibre to facilitate the carding process which burn off at a lower temperature.It is a dense , resilient high temperature refractory possessing excellent thermal properties , chemical stability and high mechanical strength.
