Light weight fire clay insulation brick is made of local top grade fire clay materials under the high temperature, which has even bulk density, high strength, low thermal conductivity and low impurity. The temperature in the 1200-1400 ℃. Ingredients are mixed with water made of plastic material or mud, mud with extrusion or pouring shape, 1250-1350 ℃ after dry burning oxidation atmosphere. The volume density of commonly used clay bricks is 0.75-1.2 g/cm3. It is a kind of essential refractory for energy saving and temperature preservation.
Light weight clay insulation brick can be used in the furnaces of iron and steel making, non-ferrous metal, buildings materials, energy industry, etc.
Specification should be different according to different furnaces/kilns, standard shapes and customized drawings are acceptable.
