- Q: Semisilica brick interpretation
- High temperature volume stability. Volume change is small.
- 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: What is the main material of silica brickIt's common, the kind we see so often!
- More than 94% silica content. True density 2.35g/cm3. With acid resistance, slag erosion performance.
- Q: How to judge the quality of brick, clay brick, high alumina brick furnace from the appearance?
- Mainly depends on the color and density of brick. Another black clay brick and brick with iron oxide formation and how much the size of bricks
- Q: How to improve the thermal conductivity of the coke silicabrick rate?
- To improve the thermal conductivity of silica brick for coke oven rate method:Manufacture of high density and high thermal conductivity of silica brick, adding additives such as CuO, Cu2O, TiO2, Fe2O3, (FeO), can improve the thermal conductivity of silica brick.
- Q: What are the main constituents of refractory bricks?
- Refractory brick composition is mainly composed of a variety of aggregate or aggregate and one or more kinds of sticky agent composed of mixed powder particles, when used, must be mixed with one or more liquids, mixing evenly, with strong liquidity. Different refractory bricks are different, such as silicon, aluminum, clay and so on:
- Q: The difference between clay refractory bricks and refractory brick in the application.
- Clay brick features good thermal shock resistance and low price, but high temperature performance is not well integrated, and the long-term use temperature is not higher than 1300 degrees. It is widely used in low temperature parts of various kilns.
- 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: The formula in the refractory brick, and firing curve, who knows?
- Iron scale powder 0.45-0.55%, cement 0.9-1.1%, lime milk 6.5-7.5%, pulp 1.95-2.2%, the silica powder, perlite will be added to the wet mill in proportion, and then add iron scale powder, cement, dry roller 1-2 minutes later
- 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.
