Ceramic fiber board is a kind of refractory material, usually composed of alumina and silicate, and it is also called an aluminum silicate board. Ceramic fiber board is made of ceramic fiber cotton, natural refractory raw materials, and a small amount of organic binder as the main raw materials, and is processed by a fully automated control continuous production line. After heating, it has very good mechanical properties and has a certain hardness support, which provides a strong guarantee for the kiln to save energy and reduce consumption, high quality, and high output.
