Ceramic fiber board is a lightweight, high-performance refractory insulation material widely used in furnace lining and thermal management systems. Manufactured from high-purity alumina-silica fibers through vacuum forming technology, it offers excellent thermal stability, low thermal conductivity, and strong resistance to thermal shock. These properties make it an ideal choice for high-temperature industrial furnaces.
In furnace lining applications, ceramic fiber board serves as both a hot-face lining and a backup insulation layer. Its low heat storage capacity allows furnaces to heat up and cool down rapidly, improving thermal efficiency and reducing energy consumption. Compared with traditional dense refractory bricks, ceramic fiber boards significantly decrease overall furnace weight, which helps lower structural load and installation costs.
Another key advantage is its excellent resistance to thermal shock. During frequent heating and cooling cycles, the board maintains structural integrity without cracking or spalling. It also provides uniform insulation performance, minimizing heat loss and ensuring stable internal furnace temperatures. This contributes to better product quality and consistent process control in industries such as metallurgy, ceramics, petrochemicals, and heat treatment.
Ceramic fiber boards are easy to cut and install, allowing flexible design and fast construction. They can be customized in various thicknesses and temperature grades to meet specific furnace requirements, typically ranging from 1000°C to 1430°C.
With its combination of energy efficiency, durability, and ease of installation, ceramic fiber board has become a reliable and cost-effective solution for furnace lining and insulation in modern industrial applications.
