    Silica Insulating Refractory Material​​ have the characteristics of low thermal conductivity, high load softening temperature, small residual expansion, and excellent reburning line change performance. They are suitable for industrial furnaces such as coke ovens, hot blast furnaces, glass furnaces and carbon furnaces. It is mainly used for the heat insulation layer and working layer of thermal equipment, and can be used for the heat insulation layer of various high temperature kiln equipment under high temperature conditions (≤1500℃) without contact with molten slag. This product is suitable for the heat insulation material of the silica brick lining of the high temperature hot blast stove of the large blast furnace and the heat insulation of the silica brick masonry of the glass furnace.




    (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.


    (7) Silica Insulating Refractory Material ​​ is also a light-weight heat-insulating brick. It has a higher heat resistance temperature than light-weight clay bricks. It can be used in heat-insulating parts to reduce heat loss and increase the efficiency of the melting process.




    Silica Insulating Refractory Material​​ are used in Metallurgy, building materials, chemical industry, petroleum, machinery manufacturing, silicate, power and other industries.

It’s widely used for the linings and insulating layers of industry kilns, and the areas without strong erosion and souring action by molten materials at high temperature.
