Clay insulating fire brick belongs to a kind of lightweight refractory brick containing Al2O3 30%~46%. Based on the principle of clay clinker or light clinker and plastic clay, clay insulating fire brick is usually produced by the combustible method, or the porous structure can be formed by chemical method or foam method. Therefore, It can ensure that the furnace wall loses less heat, and the cost of fuel will decrease accordingly. The clay insulation brick also means less heat storage, so the heating and cooling are faster, allowing for faster periodic operation. And it is suitable for the temperatures between 900℃and 1650℃.

Clay insulating fire brick is a high temperature insulation refractory material. It is made by using refractory clay clinker as raw material, plasticized clay as binder, and adding suitable amount of combustibles or foaming agent, which is widely used as inner lining brick of industry kilns wall and industry furnace.
Generally speaking, the bulk density of clay insulation brick is 0.75~1.20 g/cm3 and its compressive strength is 2.0~5.9 MPa, whose thermal conductivity is 0.221~0.442 W/(m.K) (1350℃).
Clay Insulating Fire Brick Uses
Clay insulating fire brick has a wide range of applications. It is mainly used in thermal boilers, glass kiln, cement kiln, fertilizer gasifier, blast furnace, hot blast stove, coking furnace, electric furnace, casting and pouring steel bricks,etc.
What’s more, clay insulating fire bricks can be used as thermal surface refractories or other refractory materials to support insulation, for melting furnaces, ignition kiln, flue, refining equipment, heating equipment, regenerators, gas furnaces and pipes, soaking furnaces, annealing furnaces , reaction chambers and other industrial thermal equipment.
