Silicon brick for coke furnace
Silica
Brick is the main refractory bricks used in glass melting furnace; its main
crystal phase is Tridymite. Silica Brick for coke furnace is used in
building checker chamber, chute, combustion chamber, coking chamber, and
furnace arch etc.
following characters:
（1）High refractoriness under load.
（2）High heat conductivity.
（3）Good thermal shock resistance.
（4）Solidity stable of capacity in high temperature.

Silicon brick for Glass melting furnace
glass
melting furnace
1. Silicon brick is the main refractory
bricks used in glass melting furnace ; its main crystal phase is Tridymite .
2. Main characters:
（1）High refractoriness under load.
（2）High heat conductivity.
（3）Good thermal shock resistance.
（4）Solidity stable of capacity in high temperature.
3. Applications: Due to the low creep features, the silicon bricks for glass
melting furnace are mainly used to build the main arch of the glass melting
furnace
