Q:What is the high-grade magnesia spinel brick?
Using magnesia as main raw materials, matrix co milling with magnesia and bauxite as alkaline products, high temperature burning, called magnesia brick, also called the first generation of periclase spinel brick.
Q:The difference between aluminium refractory and magnesia refractory?
The difference between the two is one is neutral, one is alkaline, the original product is different naturally.
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: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 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:What is the structure of magnesium aluminate spinel?
Mg Al spinel is a six square dense stack of equiaxed crystals
Q:What's the difference between iron spinel and magnesium aluminum spinel?
Such as aluminum spinel, iron spinel, zinc spinel, manganese spinel, chromium spinel, etc.. Due to the inclusion of different elements, different spinel can have different colors, such as magnesium spinel in red, blue, green, brown or colorless between; zinc spinel is dark green; iron spinel black, and so on.
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
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.
