- 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.
- The main raw material is the main body of refractory. Auxiliary raw materials can be divided into binders and additives. The role of bonding agent is to make the refractory body in the production and use process has enough strength. There are commonly used lignin, phenolic resin, asphalt, cement, water glass, phosphoric acid and phosphate, sulfate, some main raw material itself has the effect of binder, such as clay; additive is to improve the production of refractory materials and construction technology, or strengthen the refractory material of some properties, such as stabilizer, water reducing agent, inhibitor, plasticizer, foaming agent, dispersing agent, bulking agent, antioxidant.
- Q: Semisilica brick interpretation
- High temperature volume stability. Volume change is small.
- Q: What is acid refractory?
- Acid refractory material usually refers to refractories with SiO2 content greater than 93%. Its main characteristic is that it can resist acid slag corrosion at high temperature, but it is easy to react with alkaline slag.
- 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: Why is the three oxidation of two silicon is very harmful impurities in silica brick
- Heating calcination is the best way to extend this sort of impurity removal. Remove impurities
- Q: Can not use it two brick
- Acidic silica brick refractory material, has good ability in acid slag erosion
- 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: Why is the highest brick coke oven temperature measuring point temperature not exceeding 1450
- That is because the brick load softening point the maximum temperature is 1450 degrees.
- Q: Why in the production of the brick to detect the volume density
- Fast density test, please consult an instrument.
- Q: The formula in the refractory brick, and firing curve, who knows?
- By silica powder, 81-85%, perlite 15-19%, plus the total weight of the main raw materials of the following accessories
