1、Magnesium-aluminate spinel nuburned brick
The magnesium-aluminate spinel unburned bricks are prepared using high quality fused magnesite as main raw material, adding special additives, high pressure shaping and low temperature heat treatment. The bricks are featured with good thermal shock resistance, good corrosion and erosion resistance. Products with different brands are suitable for different service areas.
Physical properties and chemical composition of Magnesium-aluminate spinel unburned brick
2、Snorkels
The RH refining furnace snorkels are comprehensively lined using MA95 magnesia spinel bricks and high quality corundum spinel castables. The circulation tubes are assembled using MA95 magnesia spinel bricks. The products are featured with good corrosion and erosion resistance, and thermal shock resistance.
Physical properties and chemical composition of Snorkels
- 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:The difference between aluminium refractory and magnesia refractory
- Magnesia refractory belongs to alkaline refractory materials refers to refractory products such as magnesia magnesia brick magnesium iron spinel magnesium aluminum spinel magnesia ramming materials and other products of raw materials is the main crystal phase is periclase magnesia products
- Q:Spinel compound brick composite layer pollution layer does not affect the use of theoretical basis for it
- The study of mg Al spinel synthesized with MgO raw materials and Al2O3 raw materials (calcined alumina or alumina) has begun as early as 1930s. Magnesia alumina spinel was synthesized from industrial alumina and activated alumina in 1939 and used for making bricks. In 40s, people found that the addition of alumina powder in magnesia could improve its thermal stability, this is actually a spinel bonded brick. When the magnesia brick is mainly used in cement kiln, but in addition to the production of white cement kiln, it was replaced by magnesia chrome refractories.
- 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:Characteristics of sintered spinel used in refractory zzjsnc
- For the production of castable for ladle lining steel plate greatly improve the anti erosion ability. It is widely used in steelmaking refractories provides new raw material for the production of high quality synthetic stone pre sintered spinel prepared amorphous and amorphous high purity refractory material
- 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: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?
- There are structure of refractory refractory material in the crystal phase, especially the direct combination of high melting point and so on, the resistance to high temperature also tend to benefit. Compared with the ordinary brick, the second phase of the refractory products, make the products refractoriness under load are improved. Many according to mineral composition of refractory material named, such as mullite corundum brick, corundum mullite brick, is its main crystal phase and the second phase composite named. The former is mainly crystal phase, the latter is sub crystalline phase.
- Q:What is the structure of magnesium aluminate spinel?
- The crystal is composed of eight faces, eight bodies and twelve faces of diamond
- 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.
