General Information of Silica Brick For Coke Oven-G94

Our corporation produces a comprehensive range of silica bricks, with high silica content, all of these bricks exhibit excellent performance.

Our Silica bricks are the final result of blending excellent tridymite and cristobalite, as the main raw materials with cutting-edge technology, after mixing, drying, forming, in the high temperature shuttle kiln. There are also little quartz and vitreous within. We ensure you that the silica bricks made by us possess high quality standard and have gone through all the complicated quality control parameters. Their durability and strength adds life to the structure and they have the capacity of bearing high temperature.

Our competitive Advantage:

1.Competitive Price. Make the products competitive in your market.

2.Abundant Experience. Prevent cracks and twist in bricks.

3.Different Moulds. Save mould fees for you.

4.Lower ferric Oxide,porosity,higher refractoriness,density,higher CCS and exact tolerance.

5.Strict Quality Control. Meet clients’ quality requirement.

6.Safty packing,prompt delivery time,and excellent after-sales services.

7.Large stocks. Guarantee prompt delivery.

8.Professional Packing. Avoid damage and secure the goods in transportation

Q: The hot blast stove when the temperature did not rise against the brick interface decreased: How to keep the brick masonry temperature not lower than 600 DEG C, while the exhaust temperature is not higher than 400 DEG C.

Q: Semisilica brick interpretation: Good thermal shock resistance. In use, more high viscosity glass phase can be formed, and the masonry brick joint and the working surface are dense and the masonry is complete, which is beneficial to improve the impermeability of the masonry and reduce the erosion effect of the slag on the masonry.

Q: How much is the highest melting point of silicon?: . True density 2.35g/cm3. With acid resistance, slag erosion performance. Higher high temperature strength. The softening start temperature is 1620~1670 degrees. Long term use at high temperature without deformation. The thermal shock resistance is low (the heat exchange in water is 1~4 times). The natural silica is used as the raw material, and a proper amount of mineralizer is used to promote the transformation of quartz into quartz in the body. Slowly sintered at 1350~1430 DEG C in the reducing atmosphere. The total volume of heating to 1450 DEG about 1.5~2.2% expansion, the residual expansion will make cutting seam sealing, ensure masonry tightness and good structure strength, so that the brick load softening temperature will reach 1750 degrees Celsius above 1620 degrees in the case of the highest melting point.

Q: Glass kiln brick for physical and chemical indicators?: Glass kiln with high quality silica brick products according to the standard JC/T615-1996, the single brick is divided into 3 grades: XBG-96, ZBG-96, DBG-96.

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!

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: What is the silica refractory products?: High silicon content in high temperature expansion sintering temperature between 1390-1410 in furnace arch

Q: Why in the production of the brick to detect the volume density: Product quality control of silica brick.

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.
