Product Description
| Description of bauxite buyer |
There are several different models of raw bauxite,we own have three bauxite quarry,and can produce 5000 tons bauxite per month.
| Classification of bauxite buyer |
| 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.

- Q: What kinds of fireproof and fire retardant materials are there?
- recommend new Nano-insulation refractory insulation material Aerogel material, which consists of 99% pores of different sizes. it is not only the lightest and the most remarkable insualting material, but also having hydrophobic porous particles. 1830s invention.It has low thermal conductivity,not susceptibale to electrical, thermal and impact of sound with strong physical stability. It is a good insulator, but also has a strong impact resistance, three times the weight of the same volume of air. It is not heavy and can be used as heat insualting materials,buffer?materials, sound proof materials. It has attracted world attention and will be widely used in the future. Aerogel (Aerogel) features: Nontoxic to humans, insoluble in water, no burning, odorless, the world's lightest, low thermal conductivity. Aerogel heat shield is a new industrial insulation products. New products based on nanotechnology materials Aerogel, Aerogel materials in foreign countries has been widely used. We find it a lot better than the traditional insulation materials. To this end, the company introduced the product to China to open the Chinese market and import the best insualting materials to oil refining, electric power, shipbuilding, chemical, industrial pipelines, aerospace, machinery and equipment industries.
- Q: Can anyone tell me the requirements of the refractory masonry?？
- Kaolin is mainly composed of kaolinite crowded minerals that is in the shpe of tiny flake which is less than two microns, tube and folding flake. The kaolinite crowded mineral consists of kaolinite, dickite, pearl stone, halloysite, etc. and its ideal chemical formula is AL2O3-2SiO2-2H2O. The main mineral component of it is kaolinite and halloysite.In addition to the kaolinite crowded mineral, kaolin is accompanied by other minerals like montmorillonite, illite, pyrophyllite, quartz and feldspar. The chemical composition of kaolin contains large amounts of AL2O3, SiO2, and a small amount of Fe2O3, TiO2, and traces of K2O, Na2O, CaO and MgO, etc. The white pottery is made of kaolin. At present, the internationally accepted scientific name for kaolin is Kaolin which is derived from the kaolin mountain in the eastern suburb of kaolin village in Jingdezhen.Such special properties of kaolin as its plasticity,cohesiveness, certain dry strength, sinterability and firing whiteness make it the main raw material for ceramic production; properties like whiteness, softness, high dispersibility, and adsorbability allows it to be widely used the paper industry. In addition, the kaolin is also widely used in some industrial sectors such as rubber, plastics, refractories, oil refining as well as agriculture sector and cutting-edge technology for national defense. According to the purpose and requirements, kaolin can be processed and purified and it can be used to manufacture activated clay.
- Q: How to use fireclay?
- Mix refractory cement (ie aluminate cement CA50) with some refractory aggregate (bauxite, slag from flint clay) and powder (ie, crushed aggregate). Add some water to the mixture and stir, and it can be used. The clinker can be refractory powder.
- Q: Who knows the fire rating of fire?partition with steel stud?
- 1 hour. It is in line with the fireproof test standards of national building materials . CaSo4.2H2O is molecular structural formula of gypsum which contains 20% water, crystal water and free water. When 10% water slowly evaporates on the flame surface, there is still 10% crystal water. Itself is grade A fire retardant material. It can reach up to four hours at most.
- Q: What's the difference between refractory metal raceway and fireproof raceway?
- Hello, I'm very glad to answer your question. As far as I know, anti-fire groove box is made by the polymerization reaction of high polymer material and halogen-free flame retardant polymeric material. It possesses excellent mechanical properties and environmental protection property, nice appearance, and diversified colors. As a kind of fully enclosed cable bridge, it is applicable for communication signals, and laying of computer cables and control cables of highly sensitive systems. When used in heavy corrosive environment and outdoor dust environment, it has good protective effect on cables. It boasts many advantages of fire retardance (fire resistance rating is above B grade), corrosion resistance, anti-aging, high strength, light weight, and easy installation. Hope my answer is helpful for you. Hope my answer can be accepted.
- Q: What are the technical requirements for refractories?
- How high the temperature is and what is this refractory?
- Q: How many grades of fire?rating are there for interior decoration materials?
- It can be divided into construction classification and fire resistance rating. Fire prevention for buildings. Fire prevention measures should be taken in the architectural design to prevent fires and reduce fire hazards to life and property. Building fire protection includes two aspects: fire prevention before fire disaster and measures in fire disaster, among which the former is mainly to confirm the fire resistant rating and fire-resistant structure.
- Q: What are the fireproofing materials of the external wall included?
- According to the external wall thermal insulation materials, the external insulation materials is in general divided into Class A and Class B. The A class is non-combustible material. The B class is combustible materials. The fire disasters of the CCTV building and Shenyang hotel are both caused by the B level materials. Generally, the A level material will be used, and some prices are even cheaper than the B-grade material. A level is roughly divided into thermal?mortar, phenolic foam Board, rock wool board, foam cement board, and so on. I hope my answer will help you!
- Q: Fire insulation and fireproof insulation board materials What is the difference in performance?
- Fireproof Materials prevents burning through insulating while others by chemical reactions. The overall heat conductivity coefficient of Insulation materials are generally lowered by thermal conductivity of the material itself and the structure of it. Inorganic active insulation material uses ordinary cement, insulation stone, calcium powder, Platycodon grandiflorum as the main raw material.
