General Introduction:
Zero thermal expansion silica brick is also known as fused-quartz brick or thermal shock resistance silica brick.
It has extremely low thermal expansion rate, excellent thermal shock resistance, high SiO2 content etc. Zero thermal expansion silica brick is widely used in hot repair project on coke oven.
By using zero thermal expansion silica brick, the maintenance time for coke oven shortens greatly.
Cunse has the ability on providing the hot repair solution on coke oven, we also can do the EPC project on regular maintenance of coke oven.

- Q: The introduction of silica brick
- The silica mineral phase is mainly composed of tridymite and cristobalite, there is a small amount of quartz and glass
- 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: Why is the new trend of the high thermal conductivity of silica brick
- The use of high thermal conductivity of silica brick, reducing coke fuel consumption, reduce emissions of pollutants such as NOx, with considerable economic benefits and social benefits, is the future direction of the new technology of using coke oven refractory.
- Q: What is the main material of silica brickIt's common, the kind we see so often!
- 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 phosphorus and quartz. 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: 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: Can not use it two brick
- Acidic silica brick refractory material, has good ability in acid slag erosion
- Q: What are the main constituents of refractory bricks?
- Clay brick and clay brick are mainly composed of mullite (25% ~ 50%), glass phase (25% ~ 60%) and square quartz and quartz (up to 30%). Usually with hard clay as raw material, pre calcined mature material, and then with soft clay, semi dry or plastic molding, the temperature at 1300~1400 C fired clay brick products. Can also be added a small amount of water, glass, cement and other binders to make non burning products and amorphous materials. It is a refractory brick commonly used in blast furnaces, hot blast furnaces, heating furnaces, power boilers, lime kilns, rotary kilns, ceramics and refractory bricks.
- Q: Why is the highest brick coke oven temperature measuring point temperature not exceeding 1450
- 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.
- Q: What is the silica refractory products?
- High silicon content in high temperature expansion sintering temperature between 1390-1410 in furnace arch
- Q: Why in the production of the brick to detect the volume density
- Fast density test, please consult an instrument.
