Introduction to the application of refractory fiber

Refractory fiber is a fibrous refractory material and a highly effective thermal insulation material. It possesses the properties of general fibers (such as softness and high strength) and can be processed into various paper, tape, cord, felt, and blankets. However, it also possesses the high-temperature, corrosion, and oxidation resistance that ordinary fibers lack, overcoming the brittleness of general refractory materials. Furthermore, it offers significant energy savings. As a refractory insulation material, it has been widely used in various fields. The following is a detailed introduction to its applications:

Industrial Furnaces

Refractory fibers can be used for door seals and furnace curtains in various thermally insulated industrial furnaces, as well as for high-temperature flues, air duct bushings, and expansion joints.

Polycrystalline mullite refractory fiber (PMF) can be used for thermal insulation in industrial furnace linings. It is an ideal refractory material for energy-saving, low-cost, and high-quality production in high-temperature furnaces.

Petrochemical Industry

Refractory fibers can be used for high-temperature thermal insulation and heat preservation in petrochemical facilities, containers, and pipelines.

Sealants and gaskets made from refractory fibers can also be used in pumps, compressors, and valves that transport high-temperature fluids and gases.

Safety Protection

In high-temperature environments, fire-resistant fibers can be used to make protective clothing, gloves, headgear, helmets, boots, and other protective equipment.

 Automotive Industry

Automotive heat shields can be made from fire-resistant fibers.

Heavy fuel engine exhaust pipes can be wrapped with fire-resistant fibers.

Composite brake pads for high-speed racing cars can also be made from fire-resistant fibers.

Electrical Appliances

Refractory fibers can also be used for insulation in high-temperature electrical appliances.

 Other Fields

Refractory fibers are also widely used in industries such as metallurgy, machinery, building materials, shipbuilding, aviation, and aerospace. For example, in metallurgical heating furnaces, refractory fibers can be used to insulate the furnace lining, increasing the furnace’s heating rate and achieving energy savings.

In summary, refractory fibers, with their excellent high-temperature resistance, corrosion resistance, oxidation resistance, and thermal insulation properties, play an important role in numerous fields. With technological advancements and industrial development, the application areas of refractory fibers will continue to expand and deepen.
