Modules, including folding block, slicing block, Parrot block and vacuum forming block. Due to the different manufacturing methods and crystal structure of polycrystalline mullite fiber, its fiber length is short and its flexibility is poor. The polycrystalline fiber can not be applied on a large scale because it cannot be made into a large module. The polycrystalline fiber is mostly used for sticking blocks on the inner surface of castable or refractory brick furnace wall and furnace top. The use of polycrystalline fiber sticking blocks can effectively reduce the temperature of furnace outer wall and reduce the heat storage loss of furnace wall.

Ceramic fiber module is a new type of refractory lining product launched to simplify and speed up furnace construction and improve the integrity of furnace lining. The product is white in color and regular in size, and can be directly fixed on the steel plate anchor nail of the industrial furnace shell. It has good fire resistance and heat insulation effect, improves the integrity of the furnace fire resistance and heat insulation, and promotes the progress of the furnace masonry technology. Classification temperature 1050-1400 ℃.
