Clay Insulation Brick Introduction
The clay insulating brick is a kind of lightweight refractory products containing 30%~46% alumina oxide, the main materials are chamotte or lightweight clinker and plastic clay, It is usually produced by the method of combustible material, also can adopt the chemical method and foam method to form vesicular structure. The characteristics of clay insulating refractory material is of high porosity, usually 40%~85%; The low volume density is lower than 1.5g/cm3; Thermal conductivity is low, generally less than 1.0W (m.K). As the insulation material of industrial kiln, it can reduce heat loss, save energy, and reduce the weight of thermal equipment. Thermal insulation refractories have poor mechanical strength, wear resistance and slag resistance, which are not suitable for the parts of bearing structure or places contacted with slag, burden and molten metal.
