details

Insulating bricks are made of high purity  raw materials through high  temperature firing and cutting. This product has the characteristics of low thermal conductivity and low heat capacity,  so it has obvious energy-saving effect for intermittent kiln; This product has very low impurities such as alkaline content, so it has high refractoriness; The low iron content allows it to maintain good performance in a reducing atmosphere; The product has accurate dimensions, which can speed up installation, reduce the amount of mortar, and ensure the strength and stability of lining, thereby prolonging the life of kilns, furnaces or stoves; The product can be directly applied to the lining of high-temperature kilns, and has been widely used in the lining of casting furnaces, shuttle kilns, roller kilns, glass and petrochemical kilns.
