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?
- Used to make ladle casting material, greatly improve the corrosion resistance of steel lining. It is widely used in steel making refractory. The preparation of high-quality pre synthesized spinel provides a new raw material for the production of unshaped and unshaped high purity refractories
- 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?
- 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: What are the characteristics of Mg rich spinel and aluminium rich spinel?
- Occurs in the contact metamorphic zone of acid intrusive rocks and dolomite and dolomitic limestone, and is associated with forsterite, diopside and so on. It is also found in peridotite, Kimberley rock, magnesian porphyry and some crystalline schist.
- 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: 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
- The difference between the two is one is neutral, one is alkaline, the original product is different naturally.
- Q: What is the significance of the synthesis of mg Al spinel? What are the main approaches?
- The spinel has high hardness, chemical stability, high melting point and good properties, high temperature resistance in various melt erosion is very strong, so the orebody in spinel, improve the high-temperature performance of the product. Although the spinel has the above properties, the natural magnesium aluminum spinel is very few and can not meet the needs. Therefore, the synthetic method is usually used in modern times.
- 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
