    Light Weight Fire Clay Brick​ generally refer to refractory bricks with a density less than 1.3 g/cm3. Due to the characteristics of low density, high porosity, small thermal conductivity, good thermal insulation and certain compressive strength, light-weight refractory bricks have been widely used in heat treatment equipment.


    The materials of ordinary light-weight heat-resistant refractory bricks are clay, high-alumina high-strength floating bead bricks, low-iron mullite, high-aluminum poly light-insulating refractory bricks, and diatomaceous earth heat-resistant refractory bricks.

    For strength products, high-quality plate-like corundum and mullite are used as aggregates, sillimanite composite is used as a matrix, special additives and a small amount of rare earth oxides are mixed, and then subjected to high-pressure molding and high-temperature firing.


Lightweight refractory bricks Advantage:


    (1)  Light weight: using this product in construction can reduce the weight of the building and greatly reduce the comprehensive cost of the building.
    (2)  Insulation and heat insulation: During the manufacturing process of aerated concrete, tiny pores are formed inside, and these pores form an air layer in the material, which greatly improves the effect of thermal insulation
    (3)  Sound absorption and sound insulation: good sound absorption and sound insulation performance can create high airtight indoor space for you. Provide you with a quiet and comfortable environment.
    (4)  Small shrinkage value: The excellent material with a small shrinkage value ensures that your wall will not crack.
    (5)  Impermeability: The pore structure of this product makes the capillary action poor, and the water absorption and moisture conduction are slow. The time required for the same volume of water absorption to saturation is 5 times that of clay bricks.
    (6)  Environmental protection: no pollution during manufacturing, transportation and use, protect cultivated land, save energy and reduce consumption, and belong to green environmental protection building materials.



    Light Weight Fire Clay Brick​ ​​ ​is mainly used for the partition of coking chamber and combustor of coke making furnace, regenerator chamber and cinder chamber of steelmaking open hearth furnace, soaking pit, refractory material of glass melting furnace and sintering furnace of ceramics and other kiln vault and other load-bearing parts.

It is also used for high temperature load bearing parts of hot blast furnace and acid open hearth furnace top.
