- 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:How much is the highest melting point of silicon?
- Mainly used for partition, carbonization chamber of coke oven and combustion chamber open hearth furnace regenerator and a sediment chamber, soaking furnace, glass melting furnace refractories and ceramic kiln, kiln vault and other load-bearing parts. Also used for high temperature bearing part of hot blast stove and acid open hearth furnace
- 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: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: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: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:High temperature refractory material?
- Special materials often use AZS brick (i.e. corundum brick), corundum brick, magnesia chrome bricks, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials. Insulation refractories are often used diatomite products, asbestos products, insulation board. Unshaped refractories are often used refractory castable, refractory clay, refractory ramming material, refractory plastic and fettling material, fire resistance, gunning, refractory cast material, fireproof coating, lightweight refractory castable, gun mud.
- 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:The United States of our brick anti-dumping duties?
- At present of our brick anti-dumping rate is 73.10%
- Q:What is the silica refractory products?
- Refractory brick with silica content greater than 90%.
