$Magnesia-Hercynite Brick, Refractory Bricks, Magnesia-Hercynite Refractory Brick$

Q: What are the uses of magnesia spinel brick in the industry?: Instead of magnesia chrome brick sand manufacturing magnesia spinel brick used in cement kiln, not only to avoid the chrome pollution, but also has good resistance to spalling;

Q: What is the primary crystal phase? What is the secondary phase?: The properties, quantities, distribution and bonding state of the main crystalline phases of refractory determine the properties of the products directly. A lot of refractory products, such as mullite brick, corundum brick, magnesia brick, magnesia spinel brick, silicon carbide refractory products, etc., are the main crystalline phase named. What is called a crystalline phase? The second phase and second phase or second phase, refers to the refractory material and the main crystal under high temperature and liquid phase coexist, the number and influence on high temperature properties of materials is the main crystal phase is small second phases. As to the main crystalline phase of periclase magnesia chrome brick, magnesia brick, magnesia brick and magnesia calcium brick respectively containing Cr spinel, spinel, forsterite and calcium silicate two are secondary phase.

Q: Spinel refractory brick air-cooled razheng times: The components of magnesia alumina spinel refractories can be magnesia alumina spinel, excessive alumina, or magnesium aluminate spinel with excessive amount of Magnesium Oxide.

Q: Is magnesium spinel harmful to the body? Such as title magnesium spinel, harmful to the body?: The long-term intake of aluminum will eventually harm the health of the human body. These two elements are not soluble and can cause pneumoconiosis and lung cancer after inhalation.

Q: What's the difference between iron spinel and magnesium aluminum spinel?: Spinel is a mineral of magnesium aluminum oxide, because it contains elements such as magnesium, iron, zinc, manganese and so on

Q: Spinel compound brick composite layer pollution layer does not affect the use of theoretical basis for it: One is the development of the manufacturing process of the magnesia magnesia purity can be improved, with low content of magnesia silicate phase has good resistance to spalling, does not require the addition of alumina can also produce good thermal shock stability is of high quality magnesia brick; two foreign chromite resources is abundant, magnesia chrome refractories production has thermal stability good and anti erosion ability.

Q: What is the high-grade magnesia spinel brick?: Then there was the second generation of magnesia spinel brick, and its features are changed

Q: What is the structure of magnesium aluminate spinel?: Mg Al spinel is a six square dense stack of equiaxed crystals

Q: What is the significance of the synthesis of mg Al spinel? What are the main approaches?: The synthesis of magnesia alumina spinel mainly uses MgO and Al2O3 raw materials, and is obtained by electro melting, sintering or sintering

Q: Characteristics of sintered spinel used in refractory zzjsnc: Sintered aluminum magnesium spinel has good anti erosion ability, anti abrasion ability of good heat shock stability and its main use: instead of magnesia chrome sand manufacturing aluminum magnesium spinel brick used in cement rotary kiln to avoid the chrome pollution but also has good resistance to spalling
