Calcined Bauxite Grade:
| 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: 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: How many types do refractory bricks have? Where the quality of refractory material is best? What is the model?
- Sinosteel Luoyang (Luoyang Refractory Material Plant in the past): High alumina(mainly blast furnace), Gongyi. There are also a series of high-tech materials (silicon carbide, carborundum, etc.) a major producer of high alumina; silicious: Resistant material for steel, glass furnace, cement kiln); magnesia. Divide from uses and divide from chemical texture; silicious(glass furnace): Xinmi, Hennan Province, Lengshui River, coke oven, etc.). As for the models, Yixing and Changxing in Jiangsu Province: Haicheng, Liaoning Province; silicious, I do not understand your intentions; magnesia (nonferrous, steel refining; magnesia: High alumina brick; Dashiqiao area! Please put it in detail.
- Q: What characteristics do A grade external wall fireproofing material have?
- 1. Save space and reduce costs; 2. Fireproofing, green and environmental protection; 3. Waterproofing; 4. Sound insulation; 5. Thermal insulation; 6. Install easily and shorten the construction period; 7. High safety performance.
- Q: How to do environmental impact assessment for refractory Co., Ltd.
- Give you a list of data, you can refer to. List of required data for environmental impact assessment 1) name, type, specification and quantity of main process equipment. 2) the supply and consumption of raw and auxiliary materials (annual consumption and unit consumption of raw materials, ingredients, electricity, new water and recycled water). 3) public utilities: power supply system: need to build several substations? What is the size of the substation? Water supply system: fresh water consumption, circulating cooling water consumption, domestic water consumption, production water consumption, fire water consumption, respectively, how much? Heating system: if the project has a self heating system, the size of heating boilers, types, scale, fuel types, sources, annual consumption, the boiler's circulating water supply.
- Q: The classification of fire-resistant material
- Refractory material cna be divided into common and special fire proofing material. Common fire proofing material can be sub-divided in to acid fire proofing material, neutral fire proofing material. and alkaline fire proofing material according to chemical properties. Special fire proofing material can be divided into high temperature oxide refractory, refractory compounds and high temperature composite materials according to the composition. In addition, it also can be divided into common refractory products (1580 ~ 1770 ℃), high-grade refractory products (1770 ~ 1770 ℃) and super refractory products (above 2000 ℃) according to the strength . According to the shape, it can be divided into block (standard brick, special-shaped brick, etc.), special shape (crucible, sagger, pipe, etc.), fibrous (aluminum silicate, zirconia and boron carbide, etc.) and irregular shape (refractory clay, refractory castable, ramming material and so on). According to sintering process, it can be divided into sintered product, fused cast product and melting jetting product.
- Q: How to divided the grade of external wall thermal insulation materials?
- 1, According to China's national standard GB8624-97, combustion performance of building materials will be divided into the following grade level A: Incombustible building material: It is a kind of material that almost does not occur burning. Level B1: Nonflammable building material: Non-flame material has good flame resistance. It is difficult to fire under the condition of open fire in the air or high temperature, and it is not easy to quickly spread, and when the combustion?source is removed, the combustion will stop immediately. Level B2: Combustible?building?materials: Flame material has a good flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as wooden column, timber roof truss, timber beam and wooden stairs. Level B3: Combustible?building?materials: It has no any flame resisting effects, and is easy to burn, so the fire risk is high. 2, The external wall thermal insulation materials is divided by fire rating 1) level A combustion performance thermal insulation material Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. I hope my amswers are helpful to you
- Q: What is the particle size of boron carbide for refractories?
- 2 floor is right, support, learning! But what do you mean by boron carbide (d90=36.5, m)?
- Q: Why the corundum can be used as refractory
- It can resiatant to friction wear.The alumina material is a kind of neutral material with high temperature resistance, anti-acid, anti-corrosion, alkali resistance, and high hardness of corundum. The disadvantage is the poor thermal shock resistance, the main chemical composition of corundum is aluminium oxide and the melting point of corundum is 2080 degrees
