General Information
Aluminium silica brick is universal materials for the lining of molten pretreatment equipments of molten iron tank, torpedo car, etc. The products are shaped by machine power by using dense bauxite clinker and brown fused alumina as base materials and adding high quality SiC fines and high purity flake graphite. It has the advantages of excellent slag resistance, thermal shock resistance, good resistance to mechanical erosion, abrasion resistance, etc.
Features

- 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: Why will expand when heated brick
- In the process of SiO2 drying, the four crystalline transformation points of 117, 163, 180~270 and 573 DEG C are found, among which the volume expansion caused by the 180~270 is the largest.
- 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
- Small fluctuations in the chemical composition do not have a significant effect on use. The key is the operation of the electrolyzer in production to determine whether the side wall will be damaged.
- 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 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: Such purpose and scope please give me detailed points thank you because I am learning stage
- Mainly used for coke oven carbonization chamber and the combustion chamber wall, open hearth furnace regenerator and a sediment chamber, soaking furnace, glass furnace, refractory materials and ceramic brick kiln, kiln vault and other load-bearing parts. Also used for high temperature bearing part of hot blast stove and acid open hearth furnace.
- Q: How to judge the quality of brick, clay brick, high alumina brick furnace from the appearance?
- Mainly from the impurities to determine how much, generally less impurity single color brick.
- Q: Can not use it two brick
- Acidic silica brick refractory material, has good ability in acid slag erosion
- Q: How to improve the thermal conductivity of the coke silicabrick rate?
- To improve the thermal conductivity of silica brick for coke oven rate method:Manufacture of high density and high thermal conductivity of silica brick, adding additives such as CuO, Cu2O, TiO2, Fe2O3, (FeO), can improve the thermal conductivity of silica brick.
- 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.
