Composite fiber prefabricated block
Composite fiber prefabricated blocks are a type of integral full fiber furnace lining material developed by our company, suitable for use in large high-temperature industrial kilns. They are made by using a special production process to composite fibers at different operating temperatures according to temperature conduction gradients, and embedded anchoring components are used to enable the fiber prefabricated blocks to be installed on the furnace frame with high strength. They are an ideal material for solving the cost, energy life, and weight problems of high-temperature kilns.
