When it comes to kiln lining structures, ceramic fiber blankets and modules-or composite linings made from both-deliver optimal thermal performance.
01 Sealing and Filling Material
Ceramic fiber bulk cotton can be used to fill expansion joints, gaps around metal components, rotating sections at the ends of roller kilns, seams in suspended kiln roofs, and joints on kiln cars, providing effective sealing and thermal insulation.
02 Outer Layer Thermal Insulation
In ceramic kilns, ceramic fiber bulk cotton or boards are widely used as insulation materials. They help reduce wall thickness, lower surface temperature, and enhance kiln airtightness thanks to the material's elasticity and filling capability-which also absorbs thermal expansion stress in brick walls. Additionally, due to its low heat storage, ceramic fiber supports rapid firing processes.
03 Inner Lining Material
Selecting the appropriate type of ceramic fiber as inner lining material offers multiple advantages based on temperature requirements:
Reduced wall thickness and lighter weight
Faster heating-especially beneficial for intermittent kilns
Lower construction material costs
Shorter drying time and quicker commissioning
Extended service life of outer masonry
04 All-Fiber Kiln Applications
In kilns where both the walls and lining are entirely made of ceramic fiber, the heat storage is only 1/10 to 1/30 that of brick linings, and the weight is reduced to 1/10 to 1/20. This significantly decreases the overall structural weight and cost, while also improving firing efficiency.
