General Information

CMAX silica brick using high quality silica as raw material to ensure superior performance of silica bricks, the raw materials is high quality dinas rock with SiO2 of 99% min. Its unique structure helps ease forming. Moreover, advantages of complete transformation after sintering and lower residual quartz enable to produce super-duty silica bricks.

Performance:

The silica bricks for glass furnace is characterized by high purity, less impurity, good corrosion resistance, higher bulk density, complete phase transformation, lower residual quartz, high RUL, lower thermal expansion and stable volume at high temperature. This leads to increase in service life of glass furnace and reduction in energy consumption. These products have found wide application in crown and key areas and been highly appreciated by clients.

Application
CMAX Silica bricks are commonly applied in

Coke oven

Hot blast stoves

Glass furnace

$Refractory Silica Brick for Glass Furnace G-96A$

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.: Classification of chemical components of refractory materialsAccording to the chemical characteristics of refractory raw materials can be divided into acidic refractory materials, such as silica, zircon etc.; neutral refractory raw material, such as corundum, bauxite, mullite (acidic) (acidic), Ge (alkaline) iron and graphite; alkaline refractory materials, such as magnesite, dolomite, magnesium sand calcium sand.

Q: The specific content is what gb/t2608-2012 brick: The provisions of the brick classification, technical requirements, test methods,

Q: The introduction of silica brick: The characteristics of silica brick: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.The use of silica brick:Mainly used for masonry brick oven carbonization chamber, a combustion chamber and a partition wall, glass furnace and kiln roof, pool wall, high temperature hot blast furnace, glass furnace, load-bearing pool wall, hot blast stove, baking furnace of carbon bearing part of high temperature furnaces etc.. Rongsheng with refractory

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: 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. The silica mineral phase is mainly composed of tridymite and cristobalite, there is a small amount of quartz and glass. Tridymite and cristobalite and quartz remaining at low temperature due to phase change, volume changes greatly, so the brick thermal stability at low temperature is very poor. In use, under 800 degrees Celsius, slowly heating and cooling, so as not to produce cracks. The use of temperature in blast furnace so should not be below 800 DEG on. The properties and process of silica crystal with SiO2 transformation is closely related, therefore, the proportion of it is one of the important quality indexes of silica brick. General requirements below 2.38, high quality silica brick should be less than 2.35. The true density is small, reflecting a large number of scale quartz and square quartz in the brick, the residual quartz is small, so the residual line expansion is small, and the strength is decreased in useThe raw materials for the manufacture of silica brick. The higher the SiO2 content of silica raw material, the higher the refractoriness. The most harmful impurities are Al2O3, K2O, Na2O and so on. They seriously reduce the refractoriness of refractory products. Brick with SiO2 content of not less than 96% of silica as raw materials, adding mineralizer (e.g. millscale, lime) and binder (such as molasses, sulfite pulp waste liquid), after mixing, molding, drying, sintering and other processes in the system.

Q: Semisilica brick, clay brick, high alumina brick and what is the difference?: The share of A12O3 and SiO2 is different

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!
