Definition:

Alumina Silica Fire Brick​  also known as silicon insulation brick. Light refractories with silica content over 91% and bulk density below 1.2g/cm3. The refractoriness and load softening temperature are similar to those of common silica brick. However, due to many pores, the compressive strength, slag resistance and corrosion resistance are not as good as those of ordinary silica brick, while the thermal shock resistance is improved.

Using fine silica as raw material, the critical particle size is usually not more than 1mm, and the particle size less than 0.5mm is not less than 90%. A porous structure is formed by adding inflammable substances into the ingredients or gas generation method, and is made by firing. It can also be made into unburned products. It is mainly used in various parts of the kiln which require heat insulation or reduce the self weight without direct contact with the melt, without the action of aggressive gas and without the rapid change of temperature. When used at high temperature, it shall not contact with basic refractories. According to different materials, the maximum operating temperature is 1200-1550 ℃.

 

Advantage:

 

    (1) Refractoriness under load:

    The refractoriness under load of Alumina Silica Fire Brick is higher than that of clay brick and high aluminum brick, reaching 1640 ~ 1670℃, which belongs to advanced refractory materials. 

 

    (2) Thermal conductivity:

    Alumina Silica Fire Brick​ has better thermal conductivity than clay brick and high aluminum brick

 

Application:

    

  Alumina Silica Fire 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.
