High Strength Low Thermal Conductivity rerfractory

High Strength Low Thermal Conductivity rerfractory brick Composition: This series of insulating material are made from special microporous material. Producing by adopting special technology,sintering at medium temperature. Features: Comparing with congeneric product, it holds a higher cold crushing strength,lower thermal conductivity character, Featured with energy-saving and lowest bulk density. Application: That can be applied in some palces which require of insulating bricks a higher strength and lower thermal conductivity proper.Such as aluminum reduction cell, heat treatment furnace,carbon furnace ect.
