Description For Silica Brick:
Silica brick is made of quartz stone material, the content of SiO2 is above 93%,it has good resistance to acid slag and good heat conductivity. And the refractoriness is 1690~1710°C,RUL is beyond 1620°C.
SiO2 has different types of crystals in different temperatures,
and the transform between the crystals will cause the change of
the bulk. So there is a close contact between the changes of
SiO2 crystals and the produce ,performance and usage of
silica bricks. During the heating, there will be changes of the
bulk ,and cristobalite changes most, then quartz, phosphorus
quartz is the slowest of all and it also has good
heat-conductivity.Coke oven should use the silica brick with
small true density. And the phosphorus quartz is better than
others.
Application For Silica
Brick:
Mainly used in the construction of regenerative chamber, chute,
combustion chamber, coking chamber, furnace roof etc. parts of
the coke ovens.
Also be used for coke oven of coking chamber and
combustion chamber partition, steel open hearth of regenerative
chamber and sediment chamber, soaking furnace, glass melting
furnace, refractory silica brick materials and ceramic firing
kiln and kiln of the vault and other supporting parts. Also
used in hot blast stove of high temperature bearing parts and
acid open hearth furnace roof.
Advantage For Silica Brick:
1) Silicon
oxide is above 95%.
2) Good acid erosion resistance.
3) High softening point with temperature.
4) No shrink in burn repeatedly.
5) Temperature of refractoriness under load is above 1650º
C
Stable Capability, High Quality, Excellent Service, Competitive
price is the most important advantage of our products.
