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 Fire 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.

Q: Why will expand when heated brick
After high temperature after the formation of tridymite and cristobalite and quartz and a small amount of residual glass phase, quartz heating to 220-240 DEG C, in a certain degree of thermal expansion, brick maximum expansion occurs in 100~300 DEG C, 300 expansion before the total amount of expansion is about 70%~75%.
Q: What is the effect of the content of silicon nitride in silicon nitride bonded silicon carbide brick on the use of electrobath? Thank you
The main damage of silicon carbide side wall brick is stress damage, not chemical erosion. Chemical damage is formed prior to the formation of the groove, and the damage to the chemical erosion is little after the formation of the groove.
Q: The introduction of silica brick
An acid refractory consisting mainly of quartz and square quartz and a small amount of residual quartz and glass.More than 94% silica content. True density 2.35g/cm3. With acid resistance, slag erosion performance. Higher high temperature strength. The softening start temperature is 1620~1670 degrees. Long term use at high temperature without deformation. The thermal shock resistance is low (the heat exchange in water is 1~4 times). The natural silica is used as the raw material, and a proper amount of mineralizer is used to promote the transformation of quartz into quartz in the body. Slowly sintered at 1350~1430 DEG C in the reducing atmosphere. When heating up to 1450 degrees, the total volume of 1.5~2.2% expands, and the residual expansion can close the kerf and ensure the airtight and structural strength of the masonry.
Q: The difference between clay refractory bricks and refractory brick in the application.
Clay brick features good thermal shock resistance and low price, but high temperature performance is not well integrated, and the long-term use temperature is not higher than 1300 degrees. It is widely used in low temperature parts of various kilns.
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: What role does silica play in refractories?
Low fractory refers to the alumina content between 10%~30%, SiO2 content is less than 85%, semisilica brick SiO2 = 65%,The SiO2 content of not less than 93%, refractory material to natural quartz rock as the main raw materials are called silica, silica brick, silica brick, quartz glass and special products. China's literature generally put this type of product is called "siliceous refractory products", which is the most important brick.
Q: The United States of our brick anti-dumping duties?
. According to the relevant legal procedures, the United States International Trade Commission will make a final ruling on the anti dumping industrial injury before January 6, 2014, if an affirmative determination, the U.S. Department of Commerce will be involved in product release tax anti-dumping order.
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: Why in the production of the brick to detect the volume density
Product quality control of silica brick.
