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 are the applications of refractory in petroleum?
- It can be used in transportation of natural gas, filler of chemical equipment, security, insulation or even building materials.
- Q: Who knows what is the requirement for fireproofing of interior decoration materials ?
- In addition to the underground building, combustion performance level of interior decoration materials inside windowless room , in addition to a class, should advance 1 level based on the original provisions . Library, archives and rooms storing artifacts, ceilings, walls should use class A decoration materials, and the ground should use decoration materials no lower than class B. When high temperature parts of lighting and lighting lamps and lanterns are close to non - grade A decoration materials should be taken, fire prevention measures such as thermal insulation and heat dissipation must be taken. Combustion performance level of materials used for lighting should be no lower than B. Kitchen ceiling, wall and floor should used class a decoration materials.
- Q: Application of refractory materials in petroleum industry
- Our natural gas transportation, chemicals, equipment, packing, safety, insulation, and even building materials are available.
- Q: What is the difference between wear-resistant material and refractory material?
- However, the purity and the requirement are not the same. For example, brown emery is often used in abrasive paper, which doesn't matter. Refractory material uses brown corundum brick. The material used in texture and refractory material of abrasive is different. For example, it is to facilitate their forming and easy sintering. However, some other materials should be added when making brown corundum brick. In general, some top grade materials are used to make abrasive.
- Q: What does the function of SiC for refractories?
- Silicon carbide for machine non-metallic materials with high temperature wear characteristics of silicon nitride bonded silicon carbide ceramic cups and other products in a blast furnace ladle brick aluminum silicon carbide as an antioxidant added MgO-C
- Q: What is the role of the vermiculite fireproof material?
- It can be widely used in construction, decorative ceiling, wall, floor and fireproof door . Especially suitable for airport, railway station, passenger terminal, exhibition hall, hotels, shopping malls, hotels, and other public places and factory, fuel warehouses which have high requirements for fire proofing, etc. With its special thermal insulation, it can also be made to the various types of heat insulation board offered to machines (such as a variety of industrial furnace and assembly line equipment) and furniture, etc. Due to the low density of the product itself, a lot of shipyards in foreign countries use it as ceiling, wall and deck, so the development potential of the domestic shipbuilding market is huge.Expanded vermiculite is porous, lightweight, and dystectic, the most suitable for insulating materials at high temperature (below 1000℃) and fire insulation materials. In the experiment, 15cm- thick cement vermiculite burns for 4-5 hours under 1000℃, but the back temperature is only 40℃. 7 cm-thick vermiculite slate burns for 5mins through the fire flame welding net under 3000℃, the frontage melted, but you don’t feel hot with your hands holding the back side. According to aforementioned, vermiculite slate is superior than all insulating material, such as asbestos, and diatomite products.
- Q: What are the types of steel refractory materials
- (1) clay refractory brick (2) high alumina refractory brick
- Q: how does the fire endurance of first rate fire resistant window?
- class A window not less than 1.5 hours, class B window not less than 1 hours, Class C window not less than 0.5 hours.
- Q: How do refractory materials apply into pyrophyllite?
- Generally speaking, shaped refractory materials require of some powdery materials like spray grouts and iron trough in addition to pyrophyllite brick made of a mixture of pyrophyllite aggregate and powers.
- Q: Who knows about the types of Dalian thermal insulating and refractory materials?
- There are many Dalian thermal insulation materials, which can be divided into organic and inorganic thermal insulation materials. Materials include inorganic thermal insulation materials, polyfoam, mineral wool products, foam glass, expanded perlite insulation products, gelatine powder EPS grain heat insulating slurry, sprayed mineral wool, thermal insulation product of foam cements, and vacuum thermal insulation board.
