| 1.Refractory Grade: |
Refractory grade bauxite has high refractoriness, good mechanical strength and moderate slag resistance. Bauxite in the refractory industry is typically used in ladle working lining, tundish furniture, delta sections, general perpose repairment, aluminium melting furnace and mineral processing.
| 3. Rotary calcined bauxite: |
Rotary Kiln Bauxite, as the name suggests, it is the bauxite produced by rotary kiln. there are three kinds of kilns for bauxite production mainly, rotary kiln, shaft kiln and round kiln.
| 4. Shaft kiln calcined bauxite: |
Shaft kiln bauxite, the bauxite calcined by shaft kiln. the raw material-bauxite ore is loaded from the top of kiln together with coal powder and combustion improver,the fire of calcination comes from kiln bottom, about 1300-1400 ℃After the complete calcination, the bauxite is carried out from the bottom.
Application:
1.Aluminium metallurgy.
2.Precision casting/Investment casting: bauxite grog fines can be made into mold for precision casting.
3.Refractory: high alumina bauxite's refractoriness can reach 1780°C.
It is charactered by good chemical stability and mechanical performance.(Al2O3 ≥48% with low Fe2O3)
4.Aluminium silicate refractory fiber: The high alumina bauxite grog can melt under2000°C-2200°C in the electric arc furnace. After a series of processing, it can become aluminium silicate refractory fiber, which can be made into fiber blanket,plate,cloth.
5.Mixing magnesia and bauxite grog with binders to pour the molten steel ladle for better overall lining performance.
6.Producing bauxite cement.
7.Abrasives.
8.Ceramics industry.
9.Chemistry industry for all kinds of aluminium compound.

- Q: What are the meanings of azs, 34% and ec in fused brick?
- The fused brick, also called zircon corundum brick, is shorted as AZS for three chemical components in Al2O3-ZrO2-SiO2 ternary diagram. I don't know the meaning of EC.
- Q: How to detect the acid resistance of refractory? Is there any standard? Thank you
- Setting the acid resistancere of fractory products is simple; R22, two measurement methods are both bricking refractory products, using the mass fraction of the original dry to indicate. It is generally select vitriol as the medium of erosion, such as the international standard determination of the resistance to sulfate of dense shaped refractory products "(ISO8890) and PRE /, grinding fine particles to 0.63 ~ 0.80 mm, and then measure its quality loss, put it in the vitriol with mass fraction of 70%, finally boil 6 h.
- Q: How many types of special refractories are there?
- Metal ceramics, high temperature coatings, high temperature fiber and other reinforced materials
- Q: Refractory materials are needed for casting metallurgy.
- Refractory material used in foundry work is that refractories for cupola furnace? Cupola is a high temperature furnace which is used for melting molten iron, and refractory material adopted is mainly low iron high grade clay brick and clay lightweight insulation bricks, etc.foundry ingot refractory material is pearl sand (also known as pearl jewelry sand, fused ceramic, ceramic sand) it is made of high quality bauxite material by arc melting furnace.
- Q: What dose the fireproof and thermal insulation material include?
- It includes A1: Non-combustible inorganic monomer; A2 Non-flammable organic compound, namely composite material; A3 Modified phenolic fireproof materials.
- Q: How long is the duration of fire resistance that fireproof door of level B can endure?
- According to the duration of fire resistance, fireproof doors can be divided into three levels, namely level A,B,C. And accordingly, the duration of fire resistance of them should not lower than 1.20h, 0.90h and 0.60h. Fireproof door, a door that can meet the requirements of fire resistance stability, fireproof door integrity and thermal insulation at a certain time, is a fireproof separator which is located in fireproof partition, emergency staircase and vertical silo. Apart from functioning as a common door, a fireproof can also prevent the spread of fire and smoke in a certain period to make sure that people are safely evacuated.
- Q: what is the fireproofing material of engine room? who knows it ?
- machine room fireproofing materials include: Inorganic binder: The main material includes sodium silicate, gypsum, phosphates, cement,ect.; refractory mineral filler: aluminium oxide, asbestos powder, calcium carbonate, perlite, cornstarch, ect.; nonflammable organic resin: it mainly includes polyvinyl chloride, perchloro-ethylene, chlorinated rubber, neoprene latex, epoxy resin, phenol resin, ect.. nonflammable fireproof addictive: it mainly has phosphorus, halogens, nitrogen organic compounds (chlorinated paraffins, tributyl phosphate,deca-brominated diphenyl ether), and boron series (boric acid, zinc borate, aluminium borate), antimony system, aluminium series, zirconium system, etc. inorganic compounds.
- Q: What are the types of steel refractory materials
- Large steel ladle usually made with magnesia carbon brick, of course, it contains a intermediate layer (such as good a little high alumina castable), heat insulation layer and heat preservative materials Alumina-magnesia castable is OK for small steel ladle
- Q: Where do China and foreign countries do more refractory materials?
- The domestic production of refractory materials base in Henan Xinmi, Xinmi has a lot of production of refractory material factory, Zhengzhou gold refractories plant is relatively large, there is a need to go to visit the factory.
- Q: Can anyone tell me what is the material of which the mould for refractory is made？
- I can make the mould and give you a discount. If necessary, you can contact me at 261240643 (qq).
