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:What's the fire endurance of hollow brick?
For hollow brick wall, it should be noted that outside are 200-thick coal gangue hollow brick wall on interior wall. Besides, the fire endurance should comform to GB50067-97 Fireproof code for garage, repair garage, parking lot design. 3), All joints of brick walls and concrete wall column should reserve rebar tie. Masonry mortar in internal and external walls should be full. Wall masonry should be up to bottom of beam slab and filled tightly with 1:3 cement mortar.
Q:What are refractory materials?
Refractories can be divided to two categories based on the shape and three categories according to the chemical nature of acidity, neutralily and alkalinity. Alkaline refractory materials are magnesia-carbon brick, magnesia chrome brick, calcium magnesium brick and magnesia-chrome bricks. Neutural refractory mateial are high alumina brick, corundum brick and clay brick. Case-hardened refractory materials are castable, ramming mass, gunning mix, coated mix, dry vibration material, etc.
Q:What are the features of construction class A fire resistant door ?
1, fireproof and thermal insulation Foam cement board is a Class A non-combustible inorganic heat preservation material which has good fireproof performance can remain integrity after 3 hours baking at 1200℃. It can be used in buildings to improve fireproof performance.
Q:What are the grades of refractory exterior wall thermal insulation materials?
Classification of fire rating of extrior thermal insulation materials 1, According to national standard GB8624-97, the combustion performance of building materials are divided into the following grades A level: Incombustible building materials: Materials hardly burn. B1 class: Flame-retardant building materials: Flame-retardant material has good flame resistance. In case of fire in the air or at high temperature, it is difficult to catch fire and the fire will not spread quickly. And when the combustion source is removed, the burning will stop immediately. B2 Class: Combustible building materials: Combustible materials have a certain flame retardancy. In case of fire in the air or at high temperature, it will immediately burst into flames and it is easily to spread fire, such as wooden column, wooden roof truss, wooden beams and wooden stairs, etc. B3 level: Inflammable building materials: It has no flame retardant effect, and it is extremely inflammable, and the risk of fire is high. Classification of exterior wall thermal insulation materials according to fire rating: 1. Thermal insulation materials with A-level combustion performance Rock wool, glass wool, foam glass, foamed ceramic, foam cement, hole-closed perlite, etc. 2, Thermal insulation materials with B1-level combustion performance: Extruded polystyrene board (XPS) after special treatment / polyurethane (PU) after special treatment, phenolic aldehyde, gelatine powder polystyrene granule, and etc. 3. Thermal insulation materials with B2-level combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
Q:What are the main materials in concrete fireproofing material?
it can be roughly divided into: fire-resistant coating for steel structure, finishing fire retardant paint, tunnel fire coatings, concrete fire retardant coating, cable refractory coating. fire-resistant coating for steel structure is divided into: Indoor ultra-thin fireproof coatings for steel structure, indoor thin steel structure fireproofing coating, indoor thick steel structure fireproofing coating, outdoor ultra-thin fireproof coatings for steel structure, Outdoor thin steel structure fireproofing coating, outdoor thick steel fireproofing coating. I hope it can help you. Hope to adopt my opinion Thank you! )
Q:How long is the duration of fire resistance that fireproof door of level B can endure?
Level B refers to the fire resistance rating and different hours in fireproofing of the fireproof door. Fireproof door of level A can endure fire for 1.5 hours while level B 1.2 hours
Q:What high-molecular polymers can be used as fire-resistant material binder?
Lignin is the least expensive.
Q:How long is the fire-resistant time of fireproof wooden door?
Wooden thermal insulation fireproof door using flame-retardant timber or flame-retardant timber products to make door frames, skeletons of door leaf, door panels. If the door leaf need to be filled with materials, the filling materials should be fireproof thermal insulation materials which is non-toxic and harmless to human body, and matched fireproof door composed of fireproof hardware. Use doors without age limits.
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:Who knows the texture of fire-proof wooden door material?
The so-called fire doors are only posted a layer of fireproof material. Door selection still depends on the timber inside. The simplest way is to see the weight value, fireproof material layer, and they are generally paint-free doors. With fireproofing function.. Hope you adopt.
