1. Structure of Calcined Bauxite Description
Natural Bauxite of Bauxite Refractory CNBM in China with Size 1-3mm
Bauxite (aluminous soil; Bauxite) is also called the alumina or bauxite; main ingredients are alumina, hydrated alumina containing impurities, is an earthy mineral. The color is white or gray, brown and yellow or light red by iron. From 4 to 3.9 g/cm3 density, hardness, 1 ~ 3 is not transparent, very brittle, very difficult to melt. Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. Mainly used for aluminium, refractory material.
2. Main Features of the Calcined Bauxite
Natural Bauxite of Bauxite Refractory CNBM in China with Size 1-3mm
Calcined bauxite is one of the principal ore of aluminum. Calcined bauxite contains hydrous aluminum oxides and aluminum
hydroxides, formed through the laterization of aluminous rocks in tropical and subtropical areas .Calcined bauxite is obtained by calcining (heating)superior grade bauxite at high temperature (from 85OC to 1600C) .This removes moisture there. By increasing the alumina content,compared to an alumina content of about 57%to 58% in raw bauxite, calcined bauxite has an alumina content of 84%to88%.The heating is carried out in rotary kilns.

- Q: What problems should be paid attention to while using refractory materials under a controlled atmosphere?
- Pay attention to the performance of the materials, and the use of non oxide materials!
- Q: What brands are the best in the A-level refractory materials?
- 1 International (It is a well-known brand in the field of global boats and protective coatings, the products are famous for its safety, strength and smoothness, Akzo Nobel (China) Investment Co., Ltd.) 2 LANLING (It is a high-tech enterprise, and a large provider of industrial coatings, started in 1980, as well as a famous brand of Jiangsu Province, Jiangsu Lanling Chemical Group Co., Ltd.) 3 Champion (It is a high-tech enterprise who is involved in developing a number of industry standards, it is a industry-leading brand brand of Jiangsu Province Jiangsu champion coating Technology Group Limited)
- Q: How to detect the acid resistance of refractory? Is there any standard? Thank you
- What material it is. There are many kinds of refractory materials, and I basically understand all petrochemical refractory.
- Q: Which industry does refractory belong to?
- It belongs to inorganic refractory: Ceramic refractory bricks (used in steel-making furnaces) There is also organic polymer in heavy industry: Halogen-containing and halogen-free It belongs to construction industry.
- Q: Does anyone know about the classification standards of B2-level fireproof and thermal insulation materials?
- The fire-resistant differences of B1- and B2-level extruded insulation boards are as follow: B1-level materials will be smothered as soon as staying away from fire, namely, they will be extinguished after leaving fire, or be put out in 10 seconds. B2-level materials will be in low-grade combustion, namely, the fire will not get wilder, and drippings will not ignite the filter paper. I hope my answer can help you!
- Q: What's the frequently used refractory material?
- Refractory material is generally used in industrial departments like metallurgy, glass, cement, ceramics, machinery, hot working, petrochemical industry, power and national defense. Frequently used common refractory: silica?brick, semi-silica brick, clay brick, high alumina brick, magnesia brick, etc. Frequently used special refractory: AZS brick, corundum brick, direct-bonded?magnesia-chrome?bricks, carborundum brick, calcium oxide, chromium hemitrioxide, alumina, magnesium oxide, etc. Frequently used fireclay insulating refractory: diatomite product, asbestos product, insulation?board, etc. Frequently used unshaped refractory: ramming refractory, refractory castable, plastic refractory, refractory mortar, gun-mix refractory, refractory coating, lightweight refractory?castables, etc.
- 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: Does anyone knows which company produces the better refractory materials?
- I recommend Xinjiang Yuanyangrefractory material Co., Ltd. Address: Near Xishan Road No.100, Saybagh District,Urumqi. Their products are both in good quality and reasonable price. In addition, there are Xinjiang Zhongwang refractory material factory, Address: Xi hongxi Road No. 769, Urumchi City. They all have a good reputation. You may think about it. 。
- Q: What is the the best ratio of mortar in refractory cement?
- Specifical proportions are as following: 42.5R cement is 425 rapid hardening cement. Using the 425 cement to compound the mortar. The reducion of cement will naturally impact the workability of the mortar. The mix design standard of the mortar specifies the minimum amount of cement is not less than 200kg / m3. If it is composite mortar, and the strength and workability can be ensured, it is Ok to use 425 to compound. You can look for instructions of mixing proportion of mortar online as a reference.
