Q3: Can you offer Door-to-Door delivery?
A3: Yes, but only for some countries such us U.S., UAE, Saudi Arabia, Iran, and Russia, etc.
Q4: What is the minimum quantity?
A4: There is no minimum order quantity. Depending on the item and processing, there may be a minimum production required, however we can offer a quotation based only on the quantity you need.
Q5: Can you give me a brief introduction of the application of your products?
A5: CNBM (China National Building Material) core refractory business comprises the production, sale and installation of high-grade refractory products, the development and implementation of customized system solutions as well as rendering outstanding services for the key industries in Glass, Iron& Steel, Petrochemical, Cement, Ceramic and Nonferrous Metals.
- 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.
- Classification of chemical components of refractory materialsAccording to the chemical characteristics of refractory raw materials can be divided into acidic refractory materials, such as silica, zircon etc.; neutral refractory raw material, such as corundum, bauxite, mullite (acidic) (acidic), Ge (alkaline) iron and graphite; alkaline refractory materials, such as magnesite, dolomite, magnesium sand calcium sand.
- 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: What is the effect of the content of silicon nitride in silicon nitride bonded silicon carbide brick on the use of electrobath? Thank you
- Small fluctuations in the chemical composition do not have a significant effect on use. The key is the operation of the electrolyzer in production to determine whether the side wall will be damaged.
- Q: Semisilica brick interpretation
- High temperature volume stability. Volume change is small.
- Q: What role does silica play in refractories?
- The natural mineral of silica is called quartz. In refractories, silica and siliceous refractory materials contain more silica. Silica is acidic at high temperature, and siliceous refractory can resist acid slag corrosion
- 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: 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: Brick
- An acid refractory consisting mainly of quartz and square quartz and a small amount of residual quartz and glass.More than 94% silica content. 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. When heating up to 1450 degrees, the total volume of 1.5~2.2% expands, and the residual expansion can close the kerf and ensure the airtight and structural strength of the masonry.
- Q: The chemical composition of silica brick and its physicochemical index?
- The physicochemical index of silica brick:Turn left to |
- 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.
