Calcined Bauxite Applications

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 under 2000°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.


Usage 
(1) aluminium industry. Used in national defense, aerospace, automotive, electronics, chemical industry,

 daily necessities, etc. 
2 precision casting. Alumina clinker made after the mould precision casting processed into fine powder. 

Used in military industry, aerospace, communications, instrumentation, machinery and medical equipment department. 
(3) is used for refractory products. High bauxite clinker refractoriness is as high as 1780, chemical stability strong, 

and good physical properties. 
(4) aluminum silicate refractory fiber. With light weight, high temperature resistance, good thermal stability,

 low thermal conductivity, heat capacity is small and the advantages of resistance to mechanical shock. 

Used in iron and steel, nonferrous metallurgy, electronics, petroleum, chemical, aerospace, atomic energy, 

defense and other industries.

Q:Does hardware construction materials contain refractory?
refractory includes one kind of building materials. It is a special material and not commonly used.
Q:How much is the duration of fire resistance of the porous brick shale?
It’s said on the internet that 950℃ is moderate and don’t exceed 1100℃, or the bricks are inclined to be melted.
Q:How to make use of waste refractory materials whose main elements are alumina and mullite?
Crushing and pressing refractory bricks, or refractory parts . Such as welding positioner tracks use disposable tools.
Q:What material is refractory material?
Basic refractory materials, basic refractory, CaO, basic, MgO style alkaline earth oxide. The refractory materials mainly refers to magnesia refractories, dolomitic and lime refractory refractory. Main categories: (1) strongly basic magnesite brick, magnesia carbon brick, limestone and dolomite brick refractory materials;(2) alkalescent magnesia chrome refractories, forsterite refractory, magnalium and magnesia-chrome spinel refractory, basic refractory materials, high-temperature caustic slag, alkaline solvent resistance, strongly acidic slag flux or acidic refractory. The reaction is mainly used in steel furnace such as colour metal smelting furnace and cement kiln.
Q:What is the importance of silicon powder in refractory processing?
in amorphousness it is mainly the mobility
Q:Does the external wall thermal insulation materials level b1 need the fire barrier zone?
First, the cotton fire barrier zone "rock wool board" mainly uses water-repelling rock wool board produced by pendulum method as thermal insulation layer materia, and connecting and fixing base wall by binding and nail bonding, it is composed level A non-combustible building energy efficiency thermal insulation system by plastering layer composed by plastering mortar and glass fiber mesh and decorative mortar finishing layer or coating. Rock wool board exterior insulation system, low thermal conductivity, good ventilation, combustion performance advantages of higher levels can be used in new construction, expansion, renovation of residential buildings and public buildings energy-saving exterior wall insulation works, including exterior insulation, fire Barrier non-transparent wall insulation and EPS external thermal insulation system. The introduction of main level A fireproofing EIFS on the present market (The following text is selected from China Building Standard Design and Research Institute " external wall thermal insulation building construction" Standard No. 10J121) Second, the foam concrete fire barrier zone 1. It is very green without the release of irritant and harmful gases; no mineral cotton floats do harm to human skin and the respiratory tract; production of toxic gases is security level (AQ1), there is no harmful gas and waste emissions and less carbon emissions; it exist not duplicate insulation demolition waste to pollute the environment.
Q:What do RH and DH stand for in refractories?
DH :An agreement that allows strangers to build shared keys, originally invented by Diffie and Hellman.
Q:What is the particle size of boron carbide for refractories?
Ask, in the electric furnace magnesia carbon brick, boron carbide amount how many? Thank you The service temperature is around 1600.
Q:What's the type of fire proofing thermal insulation materials?
Hello! Fire proofing thermal insulation material can be classified as inorganic thermal insulation material and composite thermal insulation material. According to the form, it can be divided into fibrous veneer, mineral wool, rock wool, glass wool, aluminum silicate cotton, ceramic fiber, microporous diatomite, calcium silicate, expanded perlite, expanded vermiculite, aerated concrete, bubble foam glass, ash, glass, clay, foam concrete, and pasted paste powder polystyrene particles insulation pulp, etc. They are characterized by flame retardancy and fire proofing and thus can be used in buildings with high fire proofing class. Among them, calcium silicate, aluminum silicate and asbestos can also be used for the thermal insulation for heat supply pipelines.
Q:Who knows about the criteria of fireproof and thermal insulation materials?
The standards of fireproof and thermal insulation material. 1. the height of buildings is greater than or equal to 100 m, the combustion performance of thermal insulation materials should be A-level; 2. the height of buildings is greater than or equal 60 m but less than 100 m, the combustion performance of thermal insulation materials should be no less than B2-level. When using B2-level thermal insulation materials, fire barrier zone should be set in each floor; 3. the height of buildings is greater than or equal to 24 m but less than 60 m, the combustion performance of thermal insulation materials should be no less than B2-level. When using B2-level thermal insulation materials, fire barrier zone should be set in every two floors; 4, the height of buildings is less than 24 m, the combustion performance of thermal insulation materials should be no less than B2-level. When using B2-level thermal insulation materials, fire barrier zone should be set in every three floors.
