CERAMIC ANCHORS

Ceramic anchors are specialized fasteners designed to secure refractory materials, such as ceramic blankets, boards, or bricks, in high-temperature applications. Here are some key features and uses of ceramic anchors:

Types of Ceramic Anchors

Ceramic washers: Used with screws or bolts to distribute loads and prevent damage to refractory materials.

Ceramic clips: Spring-loaded or screw-type clips for securing ceramic blankets or boards.

Ceramic studs: Threaded or unthreaded studs for anchoring refractory materials to metal surfaces.

Ceramic nuts: Used with ceramic studs or bolts to secure refractory materials.

MaterialsCeramic anchors are typically made from high-temperature-resistant materials, such as:

Alumina (Al2O3): Provides excellent strength and thermal resistance.

Zirconia (ZrO2): Offers high thermal shock resistance and strength.

Silicon carbide (SiC): Exhibits excellent thermal conductivity and resistance to corrosion.

Applications

Ceramic anchors are used in various high-temperature industries, including:

Power generation: Boiler walls, furnace linings, and heat exchangers.

Ceramic manufacturing: Kilns, furnaces, and dryers.

Aerospace: Heat shields, rocket nozzles, and engine components.

Chemical processing: Reactors, vessels, and piping systems.

Benefits

Ceramic anchors offer several benefits, including:

High-temperature resistance: Withstand temperatures up to 3000°C (5432°F) or more.

Corrosion resistance: Protect against chemical corrosion and erosion.

Thermal shock resistance: Resist sudden changes in temperature.

Mechanical strength: Provide secure fastening and anchoring.
