- Q: What is the specific heat of a refractory bricks (clay)?
- Approximately it's about 2000; M3 specific heat is wrong with this argument, two degree clay is 1730 degrees, three degree clay is 1690 degrees, clay bricks are mixture, bulk density, 1900KG/, only elementary substance has specific heat refractoriness.
- Q: Scheme of cement kiln replacing 40 meter refractory brick kiln
- If only replace refractory bricks, it just needs three days under the condition of 200 degrees. It will be simpler if there is only free water in the refractory brick (no pouring material).
- Q: Do you use ceramic as offal material for refractory bricks?
- Use special clinker of bauxite with high alumina as main ingredient, pulp, K2O < 0, the main component is Al2O3 which is more than 18%, it is a kind of neutral refractory material, pyrophyllite fine powder doesn't need refractory brick production process, Fe2O3 < 1, grinding - mixing - molding - sintering - packaging - delivery. A.3%.3%, Fe2O3 < 0, molding and calcined from bauxite or other raw materials with high content oxides, combined with clay, K2O < 0.5%; 3: 2, raw materials 1; 4: 325 mesh.0%:
- Q: air-cooled razheng times of magnesia-alumina spinel refractory bricks
- The ingredients are magnesium, oxygen, and aluminum. the components of spinel refractory can be magnesia-alumina spinel with excessive aluminium oxide, or magnesia-alumina spinel with excessive magnesium oxide. excessive magnesium oxide and aluminium oxide can form magnesia-alumina spinel in above 1700 degrees.
- Q: What is the material of refractory brick used in the high temperature zone of the kiln?
- The ordinary generally use clay high alumious fireclay brick. GB/T 3994-2005 insulating refractory brick. What with good material is high-grade thermal insulation refractory brick. GB/T 3995-2006, high alumina thermal insulation refractory brick , model A13, is made of aluminium oxide, A13 50U, senior heat insulatio brick B5
- Q: Are sintered brick concrete bricks?
- Fired bricks are not concrete bricks.According to the different production process of bricks into sintered brick and non sintered brick. Sintered brick in China has more than two thousand years of history, is still a very wide range of wall materials.
- Q: What are the main raw materials of refractory brick and runner brick?
- Category of refractory , runner brick mainly is clay brick
- Q: do the used refractory bricks pollute the environment?
- the main pollution of refractory brick is coal gas pollution in the process of burning , it can be recycled to produce aggregate, waste brick has no pollution.
- Q: Why is the brick instead of solid clay brick
- Shale brick, shale hollow brick, shale brick, high insulation, water wall and other types of modular brick. Has the advantages of high strength, thermal insulation, heat insulation, sound insulation and other characteristics, in order to shale as the main building materials brick construction, is the biggest advantage of shale brick and clay brick traditional construction method is exactly the same, without any additional special ` construction facilities, special tools, is the best substitute for traditional clay solid brick.
- Q: What is the difference between the refractory brick and the thermal insulation brick
- Refractory bricks are used in the stove, in order to prevent from burnouting the stove under high temperature. Thermal insulation brick is used for preserving heat, is to heat preservation
