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
1.High purity
2.Long service life
3.Accurate size tolerance
4.Pure color
5. Luster appearance
6..Good thermal conductivity
7.Good creep resistance

- 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: The specific content is what gb/t2608-2012 brick
- The provisions of the brick classification, technical requirements, test methods,
- Q: What is acid refractory?
- Acid refractory material usually refers to refractories with SiO2 content greater than 93%. Its main characteristic is that it can resist acid slag corrosion at high temperature, but it is easy to react with alkaline slag.
- 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: Semisilica brick, clay brick, high alumina brick and what is the difference?
- The share of A12O3 and SiO2 is different
- 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: The chemical composition of silica brick and its physicochemical index?
- ????Al2O3 SiO2??????fe2o3??????cao???????r2o93～98?0.5～2.5?；；?0.3～2.5??0.2～2.7；??1～1.5；
- Q: What is the silica refractory products?
- Refractory brick with silica content greater than 90%.
- Q: Why in the production of the brick to detect the volume density
- Fast density test, please consult an instrument.
- Q: Physical solid waste disposal
- Preparation of silica brick pug, a certain amount of waste silica brick used to add ingredients, for the purpose of expansion and stress reduction products when firing, reduce cracks, improve the rate of finished products.
