silica bricks for coke oven
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.
silica brick for glass kiln
Mainly 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.
Silica brick application:
Mainly used in the construction of regenerative chamber, chute,
combustion chamber, coking chamber, furnace roof etc. parts of the
coke ovens.
