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

$Refractory Silica Brick for Glass Furnace G-94$

Q: Common bond brick?: When adding ingredients, the amount of lime added shall be converted to CaO, and the amount of addition varies depending on the product, usually fluctuating at 1.5~2.5%. For example, the production of coke oven silica brick, the dosage of CaO is 2.0~3.0%; the production of electric furnace top brick, the dosage of CaO is 1.4~1.75%.

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

Q: Semisilica brick interpretation: High temperature volume stability. Volume change is small.

Q: Why is the new trend of the high thermal conductivity of silica brick: The use of high thermal conductivity of silica brick, reducing coke fuel consumption, reduce emissions of pollutants such as NOx, with considerable economic benefits and social benefits, is the future direction of the new technology of using coke oven refractory.

Q: Such purpose and scope please give me detailed points thank you because I am learning stage: Acid refractory brick is mainly composed of tridymite and cristobalite and quartz and a small amount of residual glass phase.

Q: What role does silica play in refractories?: Low fractory refers to the alumina content between 10%~30%, SiO2 content is less than 85%, semisilica brick SiO2 = 65%,The SiO2 content of not less than 93%, refractory material to natural quartz rock as the main raw materials are called silica, silica brick, silica brick, quartz glass and special products. China's literature generally put this type of product is called "siliceous refractory products", which is the most important brick.

Q: Can iron oxide be used as refractory material?: Is widely used in this area. Mentioned refractory material of high school textbooks generally refers to three two aluminum oxide (alumina), alumina is also used as a refractory material, refractory crucible, porcelain, artificial gemstones.

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!
