1. Backing Insulation Layer: Serving as a permanent insulation layer behind heavy furnace linings such as refractory bricks or castables, it significantly reduces the temperature of the furnace exterior wall and minimizes heat loss.
• Hot Face Lining: In medium- and low-temperature kilns (such as heat treatment furnaces, ladle baking ovens, and aluminum alloy melting furnaces), it can be directly used as the working face lining, reducing furnace weight and enabling rapid heating and cooling.
• Furnace Door and Observation Window Linings: Used in areas requiring frequent opening due to their lightweight nature and good thermal shock resistance.
2. Insulation of high-temperature pipes and equipment
• Widely used in wall panel insulation of high-temperature flues, hot air ducts, cracking furnaces, heat exchangers and other equipment in petrochemical, electric power, metallurgy and other industries to effectively prevent heat loss and personnel burns
3. Sealing material for expansion joints and connections
• Due to its compressibility, it is often cut into specific shapes and filled in the expansion joints of kiln masonry or metal structures to absorb thermal expansion while maintaining a seal and insulation.
4. Fireproof and fire-resistant partitions
• Used as fireproof partitions in industrial buildings, fireproof door core materials, fire-resistant barriers for cable channels, etc., effectively blocking flames and high temperatures in a fire.
5. Permanent Backing for Castables
• Laying it before casting refractory castables can serve as both a formwork and a permanently retained insulation layer, simplifying construction.
6. Protection in Special High-Temperature Environments
• As a component of spacecraft thermal protection systems or for internal insulation of high-temperature testing equipment.
• The core value of ceramic fiberboard lies in its perfect combination of superior thermal insulation performance and reliable rigid structure. It is not only a highly efficient energy-saving material but also a key functional material for solving engineering challenges such as high-temperature equipment structural design, thermal expansion management, and insulation of complex shapes. From energy conservation and consumption reduction to improving equipment performance and ensuring safe production, ceramic fiberboard plays a vital role in modern industry.
