Description of    bauxite ore

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 ore
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. 


Application:

1.Aluminium metallurgy.

2.Precision casting/Investment casting: bauxite grog fines can be made into mold for precision casting.

3.Refractory: high alumina bauxite's refractoriness can reach 1780°C.

 It is charactered by good chemical stability and mechanical performance.(Al2O3 ≥48% with low Fe2O3)

4.Aluminium silicate refractory fiber: The high alumina bauxite grog can melt under2000°C-2200°C in the electric arc furnace.     After a series of processing, it can become aluminium silicate refractory fiber, which can be made into fiber blanket,plate,cloth.

5.Mixing magnesia and bauxite grog with binders to pour the molten steel ladle for better overall lining performance.

6.Producing bauxite cement.

7.Abrasives.

8.Ceramics industry.

9.Chemistry industry for all kinds of aluminium compound.

Q:Can polystyrene foam color steel plate be used as decorative fireproofing material ?
No, only non-combustible product can prevent fire. Most polystyrene foam boards are flammable which cannot prevent fire. Polyphenyl can only retard flame, highest fire retardant fire rating being B1 level. Under the same conditions, fireproof performance of polystyrene foam board will be better because most extruded sheets are made by recycling materials and contain much more impurities which will affect flame resisting property. The second reason is that high temperature in extruded sheet manufacturing technique will decompose part of flame retardants. For B1 level extruded sheet, it is difficult to reach 30 burning oxygen index, while for B2 level, it is hard to reach 32. So polyphenyl board is safer.
Q:What refractory material does cupola lining use
Refractories for ehongtianlu, Yong, eajliao, najhuo cupola, refractory (refraetoriesfo:Cupola, furnace) masonry cupola and related parts. The utility model also discloses a heating furnace, which is a thermal equipment for melting pig iron in the casting industry and certain steel smelting plants. The working temperature of the guard is usually 1400 ~1 stone.. C.
Q:I wanna ask that magnesium oxide is refractory?
Yes, Magnesia belongs to ionic crystals, the oin of magnesium has two charge, oxygen and magnesium ions are relatively small radius, these two factors make a lot of magnesium oxide lattice energy, high melting point is up to 2800 degrees Celsius. Because the magnesium oxide is stable and not react with water, it is widely used as a refractory material.
Q:what materials can make external wall fireproofing paint have the fireproofing effect
Fire retardant coatings are generally used for fireproofing and fire retardant of steel structure buildings, large stadiums, railway stations, thermal power station, nuclear power plants, urban tunnels, large-scale industrial plants, warehouses, flammable material surface. Improve the refractory time of buildings and combustible materials.
Q:Fire insulation and fireproof insulation board materials What is the difference in performance?
What is the difference between fireproof insulation board and fireproof materials in their 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 the material. Inorganic active insulation material uses ordinary cement, insulation stone, calcium powder, platycodon grandiflorum as the main raw material, produced after numerous tests with advanced production technology and chemical technology. Products features fire retardant,anti-aging properties and stable performance, low deformation coefficient, environmentaly friendly, compatible with the wall base layer and plastering layer. It has good security and stability and is as durable as ordinary buildings. Strong fire resistance: Fire insulation board is made of inorganic materials (cement), fireproofing level reaching to A1. As it does not burn, it is fireproof.
Q:What is the definition and classification of amorphous fire resistance materials?
9.8. brick made of refractory bone material and powder material can be used directly or after adding appropriate liquid formulation Refractory paint. Refractory slinging material 6. Prefabricated cubes, bonding agent or other additives. fire-resistance sparying material compround additives. Refractory pressed into the material, binder. Refractory ramming material 3, The material is a new fire proof material without calcination Heavy aggregate and lightweight aggregate: Inorganic binding agent and organic bond, its fire resistance is not less than 1580. Refractory castables 2 mouldable refractory Classification according to the type of bonding agent: 1. Classification according to refractory aggregate. According to the production and construction method, refractory mud or refractory mire, with a certain proportion of the mixture
Q:what kind of fireproof materials is used for high rise buildings?
Recommended thickness of 1mm or more # 304 stainless steel, refractory, corrosion-resistant, easy to clean. closed balcony of high rise buildings use thickened manganese, aluminum profiles. You can also use plastic steel window, solid wooden windows. Mg-Mn alloys have excellent weldability and corrosion resistance, unstressed corrosion tendency. Mechanical properties are not good enough, the ultimate strength of 210 ~ 280MPa.
Q:What is the biggest difference between refractory bricks and clay refractory bricks? Where can I find information on the refractory bricks?
You can look up knowledge manual of refractory material to find phosphatic material, etc. Xinjiang refractory bricks, castable refractory, refractory material, silicious, corundum and alumina-magnesia: High alumina and clay refractory bricks can be divided into
Q:How long is the fire-resistant time of fireproof wooden door?
National standards define the fireproof door as class A, class B, class C, among which fire-resistant time of class A fireproof door should not be less than 1.5 hours, class B should not be less than 1 hour and Class C should not be less than 0.5 hours.
