Product Description:

Bauxite, alumina or bauxite miner , main ingredients are aluminum oxide, hydrate alumina containing impurities,

is an earthy mineral.White or grey, brown yellow or light red by iron.From 4 to 3.9 g/cm3 density, hardness, 1 ~ 3, opaque, very brittle.

Very difficult to melt.Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution.Mainly used for aluminium, refractory material.

Applications of 74% Rotary/ Shaft/ Round Kiln Alumina Calcined Bauxite Raw Material for Refractory

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.


8.Ceramics industry.

9.Chemistry industry for all kinds of aluminium compound.

Q:What's the fire endurance of hollow brick?
This question is really very simple. It is better no to exceed 1050℃, or it will be easily burnt. I think 980℃ is ok actually. Around 950℃, no more than 1100℃, or brick will be burnt and melted easily.
Q:Physical and chemical indicators of various refractory.
it depends on what it is for. There are thousands of kinds of refracroties. You should just ask what you need.
Q:what's the classification of fireproof and thermal inuslation matertial?
1. thermal insulation material with A class combustion performance. Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite (2) thermal insulation material with B class combustion performance: extruded polystyrene board after special processing (XPS)/ polyurethane after special processing (PU) , phenolic aldehyde, gelatine powder polyphenyl granule. 3,thermal insulation material with B2 class combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane (PU), polyethylene (PE),etc. sea capacity module and vitrified micro bead(cooperate with the innovator of vitrified micro bead, Liu Weihua) fireproofing issues have been completely solved.
Q:What do we mean by saying that a ladle cover knots, elbow knots, blowpipe knots in refractory materials? What is the “knot”?
Go eastward 200 meters from the south gate of cultural square.
Q:How can refractory material of the electric furnace be used for longer.
I do not know if you are referring to super high power arc furnace for steelmaking, if you are, I have a easy solution for I have been doing this work.
Q:Preparation of refractory clay
Is it to make refractories? Add some andalusite to the refractory mortar will improve the effect.
Q:what's the materials of fireproof housing?
I'm very glad to answer for you. 1. Mobile homes in high-rise buildings, as for the interior hidden artifacts of single and multi-layer mobile homes, when its fire endurance is ruled above 1.5 h, you should choose the non-swelling large activity fire retardant coating; 2.as for Indoor mobile house, light roof mobile house and mobile house need to be decorated, when its fireproof limit is ruled under 1.5 h, you can choose swelling mobile house fire retardant coating; 3. The fire endurance of mobile houses need to be above 1.5 h, outdoor mobile houses project shoule better not choose swelling fire retardant coating. 4. Indoor mobile houses extremly need to be decorated, hot standby is a living place of mobile houses, bearing steel structure of equipment, bracket, the part easy to be knocked like skirt, its fire endurance needs to be above 1.5 h, you better choose fireproof panel of mobile houses. 5. Open mobile houses, you should choose fire retardant coating of mobile houses suitable for outdoor, and use the coating with over one-year outdoor mobile houses project operation and the coating function without significant changes. 6. multiple layer coating should be matched with each other, the bottom layer coating should be able to be used with rust-proof paint together or have rust-proof function. 7, while choosing the fire retardant coating for special function, it should have over one-year project operation and verification case and matched fire-proof function.
Q:whether the aluminum silicate thermal insulation material is fireproof or not?
Yes, it is fireproof. Refractory thermal insulation material mainly refers to the inorganic thermal insulation materials and composite thermal insulation materials. According to the shape it can be divided into: Fibrous finishing, mineral cotton, rock wool, glass wool, aluminum silicate wool, ceramic fiber,ect.. it takes the flint clay clinker as raw material, produced by the fusion of resistance or electric arc furnace and the injection of fiber forming. characteristic: Low thermal conductivity, excellent thermal and chemical stability, without binder and corrosive material.
Q:Is the refractory reached British BS standard and used for cables in China at present ceramic silicone rubber?
Which standard? Please be more specific
Q:How is the fire endurance of the fireproof paint?
Fireproof endurance. fire resistance test of certain building components showed by standard time temperature curve from starting of fire to lose the supporting capabilities or its integrity or fireproof property. The fire proof endurance is 5hours.
