$Glass Furnace Application Refractory Silica Brick$

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

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: 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: The brick is mainly used in the place?: 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.

Q: The United States of our brick anti-dumping duties?: . According to the relevant legal procedures, the United States International Trade Commission will make a final ruling on the anti dumping industrial injury before January 6, 2014, if an affirmative determination, the U.S. Department of Commerce will be involved in product release tax anti-dumping order.

Q: Common bond brick?: Lime should contain a lot of active CaO, I decompose CaCO3 and MgCO3 not more than 5%, Al2O3+Fe2O3+SiO2 no more than 5%. When the content of large particles, burned Ca-CO3 and over burned lime, the product produced caves, affecting the quality of products.

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: 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: 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
