- 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: 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: Why will expand when heated brick
- In the process of SiO2 drying, the four crystalline transformation points of 117, 163, 180~270 and 573 DEG C are found, among which the volume expansion caused by the 180~270 is the largest.
- 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: Can not use it two brick
- Acidic silica brick refractory material, has good ability in acid slag erosion
- Q: How to improve the thermal conductivity of the coke silicabrick rate?
- The content of SiO2 is 98.23% crystalline silica as raw material, with sulfite pulp liquid as binder, millscale and lime as mineralizer, by Jin Hongshi (TiO2) as additive, can improve the rate of thermal conductivity of silica brick for coke oven. When the rutile content is 1.5%, the coefficient of thermal conductivity of silica brick for coke oven is 2.66W/ (m.k).
- 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
- Density is the property of material, different density of materials, density of the same kind of material is not up to standard, affecting performance.
- Q: High temperature refractory material?
- Basic refractories in Magnesium Oxide and calcium oxide as the main component, the main products are magnesia brick, magnesia chrome brick, magnesia zirconia brick, magnesia brick, magnesia spinel brick, magnesia calcium brick, dolomite brick and the latest development of magnesia spinel brick and so on. With Magnesium Oxide (MgO) more than 80% of the refractory brick called magnesia brick,
