Ceramic Fiber Special-Shaped Parts

Vacuum-formed to the drawing

Ceramic fiber special-shaped parts are vacuum-formed to equipment drawings and site conditions for non-standard and irregular insulation sealing needs. Low thermal conductivity gives stable high-temperature insulation, and the material has thermal and chemical stability, so it resists powdering and cracking and ages slowly in conventional dry flue gas. Formed rigidity resists conventional furnace airflow, and installation is simple because the shapes are regular. Where wear or erosion is a concern, the surface can be coated with a vacuum-formed hardener or refractory mortar.

Scope of application

• Kiln observation holes, temperature measurement ports, burner ports and furnace door insulation seals.
• Non-ferrous metal melting launders and trough body insulation linings.
• Casting industry riser insulation components.
• High-temperature connection sealing gaskets for electromechanical equipment.
• Radiant insulation blocks and high-temperature cavity insulation in civil heating equipment.

Working condition restrictions

Only for dry, static, low-erosion high-temperature conditions. Not suitable for strong acid or alkali corrosion, water immersion, high-speed airflow erosion, frequent mechanical impact or high-pressure extrusion.

Usage precautions

• A traditional ceramic fiber (RCF) product, different from bio-soluble fiber; cutting, grinding and installation release dust, so wear a dust mask and gloves with ventilation.
• Waste must be disposed of under local environmental regulations and must not be discarded arbitrarily.
• Over-condition use can cause cracking, powdering and detachment.
• All technical data are for reference; grades differ in temperature resistance, so select and test against the actual condition.
