Rongsheng lightweight clay bricks refer to lightweight refractory bricks containing 30% to 46% Al2O3. Clay clinker or lightweight clinker and plastic clay are the main raw materials. Usually produced by the combustible method, the porous structure can also be formed by the chemical method or foam method. The ingredients are mixed with water to form plastic mud or mud, which is extruded or cast, and then fired in an oxidizing atmosphere at 1250 to 1350 ℃ after drying.

Physical and Chemical Indicators of Lightweight Clay Bricks

The volume density of commonly used lightweight clay bricks is 0.75 ~ 1.20 g/am3, the compressive strength is 2.0~5.9MPa, and the thermal conductivity is 0.221 ~0.442 W/(m·K) (1350℃). Lightweight clay bricks are divided into ten grades according to volume density: NG-1.5, NG-1.3a, NG-1.3b, etc.

Application of Lightweight Clay Bricks

Lightweight clay bricks have a wide range of uses and are mainly used as insulation layer materials in various industrial kilns that do not come into contact with melts and have no effect on corrosive gases. The operating temperature is 1200~1400℃.
