alumina silica bricks refractory fire clay firebrick for electric oven
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
thecoke 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.
