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:what is best for making refractory insulation for Blast furnace, hot stove.
high alumina insulating brick diatomite brick
Q:How many hours of the fire endurance time of the rock wool laminboard?
The fire endurance time of the rock wool laminboard is generally adout 1 or 2 hours.
Q:Why can aluminium hydroxide not be used to make refractory material?
Hope my answer is helpful to you. It decomposes and produces aluminium oxide and water after heating, chemical equation for the reaction is: 2Al(OH)3=△=Al2O3+3H2O. Aluminium hydroxide can't be directly used to make refractory material because aluminium hydroxide is not stable.
Q:What are the insulation fireproofing materials?
Insulated shoes, insulated gloves, tape (cloth, plastic, as well as waterproof) yellow wax tube, mouth care, fireproof (ie asbestos cloth is sold by jin) there is pressure-caps black tape, waterproof tape ,casing. There are glass fiber needle felt is widely used in electrical, chemical, construction, transportation, automotive and other industries interlayer insulation and silencer system, and used as an insulating fireproof material.
Q:What are the material requirements of class A fire resistant door ?
It must meet standards of the national regulation. You may search on Baidu.
Q:What is the the best ratio of mortar in refractory cement?
Specifical proportions are as following: 42.5R cement is 425 rapid hardening cement. Using the 425 cement to compound the mortar. The reducion of cement will naturally impact the workability of the mortar. The mix design standard of the mortar specifies the minimum amount of cement is not less than 200kg / m3. If it is composite mortar, and the strength and workability can be ensured, it is Ok to use 425 to compound. You can look for instructions of mixing proportion of mortar online as a reference.
Q:What are the commonly used fire protection materials
Firewall. The fire wall is made of non combustible material, and is directly installed on the base of the building or the reinforced concrete frame or fire proof walls . Fireproof limit of the firewall, according to the current "building regulations", is 4 hours, wheras the specification of Technical specification for concrete structures of tall building is 3 hours. doors resistant to fire, heat in a certain period of time These door usually prevent the spread of fire and gas in the fire resistant wall, staircase, pipe well. Fire door can be divided into steel fire doors, wood fire doors and composite materials fire door according to the material used. According to the limit of fire resistance can be divided into the class A fire door (1.2h), B fire doors (0.9), class C fire door (0.6h); (3) fire window. Windows resistant to fire, heat in a certain period of time It is usually installed in the fire resistance wall or doors; the fire shutter. This roller shutter can be refractory in a certain period of time. It is typically used for heat and fire insulation in escalator with difficulties to install fire resistant wall, fire resistant valve and smoke resistant valve. Fire resistant valve is installed in the ventilation and air conditioning system of air supply and return air duct, usually in the open state, fire, It will be turn off when the pipeline gas temperature reached 70 degrees, can meet the requirement for fire resistance and insulation for gas and fire. Smoke fire resistant damper installed in the exhaust system pipe, when the pipeline gas temperature reached 280 degrees, it will close automatically, insulating fire and gas.
Q:How many kinds of A-level fireproof and thermal insulation materials are there?
Inorganic insulation materials basically can achieve the goal, such as glass wool, rock wool, and foam glass. The phenolic foam in the organic foam material is special. Phenolic foam is not only good at insulation, but also good at compounding with steel and other materials to achieve A-level performance, and the A-level insulation materials are: Rock(ore) wool, foam glass and inorganic thermal insulation mortar.
Q:Which basic refractory is better?
Zhengzhou Xindeyuan Refractories Co., Ltd.and Zhengzhou Rongsheng Kiln Refractories cO.,Ltd. Their basic refractories mainly refer to refractories with magnesium oxide and calcium oxide as main components what can resist errosion of basic slag, including magnesia bricks, magnesia-alumina bricks, magnesia-chrome bricks, dolomite bricka and so on(magnesia bricks), among which magnesia bricks is the most common. Magnesia brick containing more than 80% to 85% magnesium oxide, has good resistance to basic slag and iron slag, and higher refractoriness than clay and silica brick. It is mainly used for open-hearth furnace, oxygen-blown converter, electric furnace, ferrous metal smelting equipment and other high temperature equipments.
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.
