    The size is precise, providing kinds of shapes according to customer's drawing




     GeneralSilica Light Weight Brick can be divided into two levels: the first grade can be used in the top of the steel rolling heating furnace and the roof of the silicate industrial kiln, and can be directly in contact with the flame; the second grade is used in the general industrial kiln Insulation. Applicable to: industrial furnaces such as coke ovens, hot blast furnaces, glass melting furnaces and carbon calciners. Generally, the bulk density of silicon heat insulation refractory bricks is 0.9-1.1g/cm3, the compressive strength is 2.0-5.9MPa, and the thermal conductivity is 0.35-0.42W/(m·K). It has excellent fire resistance, its softening temperature under load is close to 1620℃ for dense silica bricks, with only a small residual expansion, and its thermal stability is better than dense silica bricks. Therefore, siliceous heat-insulating refractory bricks can be used for a long time under high temperature conditions (1500-1550°C) without contact with molten slag, but they are especially suitable for high-temperature hot-blast furnaces of large blast furnaces. Thermal insulation of silica brick gas.





The Silica Light Weight Brick for coke oven has low alkali and low content of residual quartz.

The Silica Light Weight Brick has high strength and refractoriness under load.

The Silica Light Weight Brick also has strong ability in acid slag resistance.

This Silica Light Weight Brick is used to the walls, hearth or other parts of the combustion chamber, and carbonization chamber




    Silica Light Weight Brick​​ are used in the blast furnace blast area and communicate with the blast furnace exhaust. The light silicon bricks have a temperature range of 1000 ~ 1300 ℃. Can meet the whole cycle life of hot blast stove

    Silica Light Weight Brick are also used in the partition walls of the carbonization and combustion chambers of coke ovens, the regenerators and slag chambers of open hearth furnaces, soaking furnaces, glass melting furnaces, refractory materials and ceramic firing kilns. There are also vaults and other load-bearing parts for kilns. It is also used for the high-temperature load-bearing part of hot blast stove and the top of acidic open hearth furnace.
