Glass furnace Silica brick
CMAX Silica bricks are made from high quality quartz tail sand, lime and mineralizing agent through the process of crashing, screening,mixing, pressing, drying and sintering. zircon brick is characterized by good thermal stability and resistance to corrosion and erosion of glass liquid. They are used for high temperature equipment in the glass furnace, molten steel ladle and continual casting water month.
Silica bricks for hot stoves feature sharp dimension,low expansion,little residual quartz, low true density.low creep rate,good thermal shock resistance upon 600°C and high refractoriness under load, It mainly used at high temperature area include arch and upside of hot stove and upside of checker.What’s more, we are main supplier of Morgan .

Product Picture
Produce Processing
- Q: The introduction of silica 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: Because of the recent relates to this industry, by way of learning to name for all raw materials, I hope knowledgeable friends exhibitions, thank you.
- Acidic materialMainly siliceous materials, such as quartz, tridymite and cristobalite, chalcedony, flint, opal, white quartzite, silica sand, diatomaceous earth, silicon oxide contained in these siliceous materials (SiO2) at least 90%, pure raw materials are silicon oxide as high as 99% or more. Siliceous materials at high temperature is the acidic nature of chemical dynamics, when the presence of metal oxide, or when in contact with the chemical reaction, and combined with a fusible silicate. Therefore, if there is a small amount of metal oxide in siliceous material, it will seriously affect its thermal resistance.
- 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: 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: The United States of our brick anti-dumping duties?
- At present of our brick anti-dumping rate is 73.10%
- Q: The high thermal conductivity of silica brick and traditional brick what is the difference?
- Tridymite content high thermal conductivity silica brick is 70%, tridymite content of traditional brick is 60%, tridymite content high thermal conductivity of silica brick than tridymite high content of 10% traditional brick,
- 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: Why in the production of the brick to detect the volume density
- Product quality control of silica brick.
- Q: High temperature refractory material?
- Special materials often use AZS brick (i.e. corundum brick), corundum brick, magnesia chrome bricks, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials. Insulation refractories are often used diatomite products, asbestos products, insulation board. Unshaped refractories are often used refractory castable, refractory clay, refractory ramming material, refractory plastic and fettling material, fire resistance, gunning, refractory cast material, fireproof coating, lightweight refractory castable, gun mud.
- Q: Physical solid waste disposal
- The amount of addition is related to the shape and weight of the brick. The bricks can be added to 20% weight less than 25kg; bricks above 25kg can be added to 30%; for the specific type of brick can be added 30%. into waste silica brick should pay attention to this problem
