Ceramic fiber shaped components boast excellent properties including high-temperature resistance, low thermal conductivity, light weight and impact resistance. They are widely adopted across a variety of industrial sectors. The main application scenarios and benefits are listed below:

1. Core Applications for Industrial Kilns

Sight holes and thermowell linersUsed as liners for kiln sight holes and temperature measuring ports, these parts are in direct contact with flame and high-temperature flue gas. With thermal conductivity ranging from 0.03 to 0.18 W/(m·K), they effectively block heat transfer and reduce the outer surface temperature of furnace walls by 30–50°C to cut heat loss. For example, remarkable energy saving can be achieved after application in glass melting furnaces.

Burner blocks and furnace doorsReplacing conventional refractory bricks as burner blocks or furnace door linings, they are lightweight (only 1/3–1/4 the density of refractory bricks). This greatly lowers the overall weight of kilns and reduces energy consumption during furnace startup and shutdown. Their superior thermal shock resistance against sudden temperature changes extends service life and cuts maintenance costs.

Fit for complex structuresTubes, cones, domes and other custom profiles can be manufactured via vacuum forming. They fit perfectly for curved furnace crowns and irregular furnace walls, solving the fitting problems that traditional refractory materials cannot address.

2. Key Applications in the Metallurgy Industry

Energy-saving renovation for reheating furnacesWhen used as furnace lining in steel reheating furnaces, ceramic fiber shapes raise heating-up speed by over 20%, shorten preheating time and reduce fuel consumption. A typical application is full installation from heating zone to cooling zone in cold-rolled strip annealing furnaces for high energy efficiency.

Protection for high-temperature equipmentThey serve as thermal insulation layers for ladle covers, billet transfer trolleys and other equipment. Thanks to low heat capacity, less heat is accumulated, which reduces thermal stress and prolongs equipment service life.

3. Specialized Solutions for Non-Ferrous Metal Processing

Launders and collection troughsIn aluminum production, they act as liners for metal collection troughs and flow launders. They withstand molten aluminum at around 700°C and corrosive conditions while preventing penetration of molten aluminum, securing stable production and qualified product quality.

Risers and sleeves for castingIn non-ferrous casting, they are applied as riser sleeves and runner liners to control the solidification rate of molten metal, minimize shrinkage cavities and improve yield. For copper alloy casting, custom shapes match riser geometry precisely and optimize feeding performance.

4. Expanded Applications in Petrochemical & Energy Industries

Insulation for FCC unitsIn petrochemical fluid catalytic cracking (FCC) units, they withstand high temperatures above 900°C and corrosive atmospheres. Good chemical resistance against acids and alkalis ensures stable long-term operation and reduces shutdown maintenance frequency.

Thermal management for new energyAerogel composite fiber boards are developed for battery thermal management systems. With ultra-low thermal conductivity of 0.028 W/(m·K), they deliver efficient thermal insulation for battery packs, improving safety and driving range.

5. Innovative Uses for Civil & Laboratory Equipment

Thermal radiation blocks for heating devicesAs thermal radiation blocks for commercial and domestic heaters, they optimize heat transfer paths to improve heat utilization and save energy. For instance, oven liners made of this material shorten preheating time and deliver more uniform temperature distribution.

Lining for high-temperature test furnacesAs furnace chamber insulation in laboratory high-temperature furnaces, they can withstand extreme temperatures up to 1600°C. Low linear shrinkage within working temperatures keeps the furnace structure stable and guarantees accurate test results.
