Silica brick for coke oven silica brick for glass kilnsilica 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 application:
Mainly used in the construction of regenerative chamber, chute, combustion chamber, coking chamber, furnace roof etc. parts of the coke ovens.
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.
Physical and Chemical Indicators:

- Q:What is the silica refractory products?
- High silicon content in high temperature expansion sintering temperature between 1390-1410 in furnace arch
- Q:Can not use it two brick
- The softening temperature is up to 1640~1670 DEG C, and the volume is stable at high temperature for a long time.
- Q:Common bond brick?
- Manufacturing for silica brick binder hi-li sulfate pulp waste liquid and lime milk. When lime milk is used as a bond, it acts as a plasticizer. To increase the strength of lime brick in the drying process, as mineralizer in the firing, promote the transformation of quartz.
- Q:Semisilica brick, clay brick, high alumina brick and what is the difference?
- This is a kind of refractory material is divided into three types: semisilica brick (A12O315 ~ 30%), clay brick (A12O330 ~ 48%), high aluminum brick (A12O3>48%).
- Q:Why is the new trend of the high thermal conductivity of silica brick
- The high thermal conductivity of silica brick all inherits the advantages of traditional coke oven silica brick, on the basis of further highlight the characteristics of high thermal conductivity.
- Q:The specific content is what gb/t2608-2012 brick
- The provisions of the brick classification, technical requirements, test methods,
- Q:Such purpose and scope please give me detailed points thank you
- Acid refractory brick is mainly composed of tridymite and cristobalite and quartz and a small amount of residual glass phase.
- Q:The hot blast stove when the temperature did not rise against the brick interface decreased
- How to keep the brick masonry temperature not lower than 600 DEG C, while the exhaust temperature is not higher than 400 DEG C.
- Q:The brick is mainly used in the place?
- Partitions used in coking and combustion chambers for coke ovens
- Q:The introduction of silica brick
- The characteristics of silica brick:Brick belongs to refractory materials, with strong resistance to acid slag or acid solution erosion ability, high load softening temperature are excellent properties of silica brick, usually 1640-1680 C.The use of silica brick:Mainly used for masonry brick oven carbonization chamber, a combustion chamber and a partition wall, glass furnace and kiln roof, pool wall, high temperature hot blast furnace, glass furnace, load-bearing pool wall, hot blast stove, baking furnace of carbon bearing part of high temperature furnaces etc..
