Product description
Refractory fiber board is made of ceramic fiber cotton produced by resistance furnace injection fiber forming process as raw material and processed by vacuum forming process. It is a lightweight, flexible refractory fiber insulation material, which is processed from a combination of high-purity refractory oxides and organic binders.
Application of refractory fiber board
● Ceramic industry: lightweight kiln car structure and kiln hot surface lining, kiln temperature zone separation and fire-stopping materials;
● Backing insulation for kilns in cement and other building materials industries;
● Light industry: Lining of combustion chambers of industrial and domestic boilers
Advantages of refractory fiber board
Selected raw materials: Sufficient raw materials and selected quality ensure product quality.
Fully automated production:Strict control on product quality and standardized production workshops.
