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:What advantage and disadvantages it has compared to common fire insulation materials
Advantage and disadvantages of A-level heat perserving materials of equal effectiveness 1, the component materials of A level thermal insulation materials are inorganic materials, so it is high temperature resistant, non-combustible, fire-resistant; 2, good durability, aging resisitant, and having the same service life as buildings; 3, a level thermal insulation material can be well combined without using polymeride to bond, coat mortar, reinforced net, needing only few construction procedures. It is anti seepage with few quality problems; 4, absorb few water, and can bond firmly with the cement mortar, tile adhesive tile, safe and reliable; 5, a level thermal insulation material have the same service life as buildings, without the need to increase the cost on maintenance and renovation during its life span, and can maximize resource conservation.
Q:how about the performance of aluminum silicate fire proof thermal insulation?
aluminum silicate fire proof thermal insulation board has a good performance. it is a artificial board that separates the wood and plant fiber by mechanical and chemical methods and mixed the adhesion agent and water-proofing agent, molding by high temperature and high press. MDF(medium density fibre board) structure is more even than natural wood. it avoids rot, moth-eaten and other problems, while medium density fiber board has small expansion and contraction, which is easy to be processed. Since the surface of medium density fibre board is smooth, the board is easy to paste a variety of finishings, which makes furniture more beautiful. A variety of decorative wood-based panel is to embellish their homes.
Q:Which are fire proofing thermal insulation materials?
Which are fire proofing thermal insulation materials? Which fire proofing thermal insulation materials are commonly seen?
Q:What are the models of refractory cables?
NH is the firat letter of "refractory" in Chinese phonetic alphabet; It is V, not W. PVC insulation and sheath; K in KVV represents the control cable. 5 * 10 represents the cable is made up of 5 core cables whose nominal cross section is 10 square milimeter.
Q:I wanna ask that magnesium oxide is refractory?
Magnesium oxide is used in refractory material, because it has the following characteristics and properties: 1, high stability: Anti-oxidation, anti-reduction, thermal decomposition; 2, high melting point, 2800 degrees; 3, low prices. In particular, the stability and melting point is very good, I hope I can give you help.
Q:What are the characteristics of phenolic resin as a refractory material?
Q:What are the characteristics of clay refractory materials?
Clay refractory has excellent performance in anti fatigue. The fatigue strength of the general metal is 50% ~ 40 of the tensile strength, and some composite materials can be as high as 70 ~ 80%. The fatigue fracture of the composite is from the matrix, which is gradually extended to the interface between the fiber and the matrix. Therefore, the composite material has omen before destruction, and it can be checked and remedied. Fiber composite material also has good performance in anti vibration fatigue. The fatigue life of The helicopter rotor made of composite material is longer that made of metal. I hope my answer will help you!
Q:What crusher is used for raw material of broken refractory material? What is the rough crushing process? What are the materials? Thank you!
Now cone crusher is generally used.
Q:How can refractory material of the electric furnace be used for longer.
Minimize mechanical shock, Electrical furnace commonly referred to must be electrical arc furance. The wall of electric arc furnace should be constrcuted with magnesite carbon brick. Its hearth permanent layer should be constrcuted with mansornary magnesia brick. High alumina brick is usually used to aviod furnace cover suddenly get hot and cold. But its service life is lower. At present integral casting furnace cover is made of alumina magnesia. Terminal will be created even without the use of refractory material. Consumption is much faster if using refractories material or whole knottiing mainly.
Q:Who knows about ranking rules of fireproofing thermal insulation materials for exterior wall?
(1) the height of buildings is greater than or equal to 24 m, the combustion performance of thermal insulation material should be A-level. (2) the height of buildings is less than 24 m, the combustion performance of thermal insulation materials should be A- or B1-level. When using B1-level thermal insulation materials, fire barrier zone should be set in each floor. (3) incombustible materials should be used as the protective layer of thermal insulation materials. Thermal insulation materials should be completely covered by protective coatings. The thickness of protective layer should be no less than 3 mm. (4) The base walls should be set in buildings with nontransparent curtain wall structures of metal, stone,etc. The fire endurance of which should comply with relevant provisions of current fire safety rules on fire endurance of external wall. The fire endurance and fire protection construction of pier between two windows, window sill walls, skirt walls of glass curtain walls should comply with relevant provisions of current fire safety rules on building curtain walls. (5) the internal cavity of base walls, as well as the space between the skirt wall and base walls, pier between two windows, window sill walls should be sealed with fire-proof sealing materials at each floor.
