General Information
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
Application of the refractory silica bricks
Silica brick is mainly used for Coke oven, glass kiln, hot-blast stove, tunnel kiln,Acidic furnace non-ferrous metal smelting and some other thermotechnical equipment in good furnace building materials.

- Q:How to judge the quality of brick, clay brick, high alumina brick furnace from the appearance?
- Mainly depends on the color and density of brick. Another black clay brick and brick with iron oxide formation and how much the size of bricks
- 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:The formula in the refractory brick, and firing curve, who knows?
- By silica powder, 81-85%, perlite 15-19%, plus the total weight of the main raw materials of the following accessories
- Q:How much is the highest melting point of silicon?
- Acidic silica brick refractories, softening temperature is as high as 1640 to 1670 DEG C, in the long-term use volume is relatively stable under high temperature. More than 94% silica content.
- Q:Why is the three oxidation of two silicon is very harmful impurities in silica brick
- Can generate the material needs is the best way to see the impurity problem!! the first consideration is whether can get the material impurities with what method choice after the time! Miscellaneous reactions cannot have new impurity formation! Selected cannot and need material reaction reagent!
- 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:Brick
- Acidic silica brick refractory material, has good acid resistance and slag erosion, softening temperature is as high as 1640 to 1670 DEG C, in the long-term use volume is relatively stable under high temperature.
- Q:Such purpose and scope please give me detailed points thank you
- 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:The high thermal conductivity of silica brick and traditional brick what is the difference?
- The scale quartz is a spear shaped double crystal structure, very compact and favorable to the increase of thermal conductivity. The high thermal conductivity of silica brick in improving thermal conductivity and other performance indicators and traditional coke silicabrick agreement.That is to say, the high thermal conductivity of silica brick all inherited the traditional advantages of coke oven silica brick, on the basis of further highlight the characteristics of high thermal conductivity
- Q:What role does silica play in refractories?
- The production of clay brick refractory clay raw material is natural, its main mineral is kaolinite (formula Al2O3 - 2SiO2 - 2H2O), clay brick containing SiO2 in 45% ~ 65%, belongs to the weak acid refractory materials, have a certain ability to resist acid slag, but easy to be alkaline slag erosion.
