Erosion Resistant Silica Insulating Brick

Fireproof High Heat 91% SiO2 Silica Insulating Brick For hot blast stove


Standard sizing:This brick is special size for pipes of industry furance ,Special size and OEM Service also provide!
The size is precise, providing kinds of shapes according to customer's drawing




   Fireproof High Heat 91% SiO2 Silica Insulating Brick For hot blast stove are made from high purity raw material according to different brick type to meet different requirement.


They are ideal thermal insulation material usually used in industrial furnaces and heating pipe.

Our Fireproof High Heat 91% SiO2 Silica Insulating Brick For hot blast stove have excellent properties as light weight, low ferrous, low shrinkage, atmosphere erosion resistant and so on.


    Fireproof High Heat 91% SiO2 Silica Insulating Brick For hot blast stove is mainly used in various parts of the kiln that require heat insulation or reduce its own weight without direct contact with the melt, without the action of aggressive gases, or with sudden temperature changes. When used at high temperature, it must not be in contact with alkaline refractories. According to different materials, the maximum service temperature is 1200~1550℃.



1. High refractoriness, Refractoriness Under Load is similar to same SiO2 content silica brick.
2. More porosity,so compression strength,slag resistance,corrosion resistant is not better than silica brick,but thermal shock resistance is improved.
3. Use at high temperatures, can not contact with alkaline refractory materials.
4. High strengh resistance-acid erosion.
5. Highest working temperature:1200~1550°C depend on material.




  1.  in the blast furnace blast area and communicate with the blast furnace exhaust.

  2. hot blast stove

  3.  in the partition walls of the carbonization and combustion chambers of coke ovens,

  4. the regenerators and slag chambers of open hearth furnaces, soaking furnaces, glass melting furnaces, refractory materials and ceramic firing kilns.

  5.  other load-bearing parts for kilns.

  6. high-temperature load-bearing part of hot blast stove and the top of acidic open hearth furnace.
