Clay insulation brick refers to Al₂O₃30%-46% of light refractory products, with clay clinker or light clinker and plastic clay as the main principle, usually produced by combustible method, can also be used chemical method or foam method to form a porous structure.

Product features:

Insulation refractory material is characterized by high porosity, generally 40%-85%; low volume density of less than 1.5 g/cm³; Low thermal conductivity, generally less than 1.0W(m.K). It acts as a thermal insulation material for industrial furnaces, which can reduce the heat loss of furnaces, save energy, and reduce the quality of thermal equipment. Thermal insulation refractories have poor mechanical strength, wear resistance and slag erosion resistance, and are not suitable for the load-bearing structure of the kiln and direct contact with slag, furnace charge, molten metal and other parts.

Product use:

Clay insulation brick has a wide range of uses, mainly used in a variety of industrial kilns do not contact with the melt and no erosion of the gas insulation layer material, the use of temperature 1200-1400 ℃. Mainly used in thermal boilers, glass furnaces, cement furnaces, chemical fertilizer gas furnace, blast furnace, hot blast stove, coking furnace, electric furnace, casting and pouring steel bricks, etc.

Clay insulation bricks can also be used as hot surface refractory or other refractory supporting insulation for melting furnaces, ignition kilns, flues, refining devices, heating devices, regeneration devices, gas furnaces and pipelines, soaking furnaces, annealing furnaces, reaction chambers and other industrial thermal equipment.
