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: 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: 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
- 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 are the characteristics of Mg rich spinel and aluminium rich spinel?
- Magnesium spinel is a subspecies of spinel, which is MgAl2O4, also called spinel. An equiaxed crystal having eight crystalline or irregularly granular crystals.
- 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?
- The crystal is composed of eight faces, eight bodies and twelve faces of diamond
- Q: The difference between aluminium refractory and magnesia refractory
- Aluminum refractory belongs to neutral refractory material, usually refers to silicon aluminum refractory materials, such as: high alumina brick, clay brick, high alumina castable and other products, the production of raw materials is mainly bauxite.
- 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
