Product Description of 70% Rotary/ Shaft/ Round Kiln Alumina Calcined Bauxite Refractory Raw Material:
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.
Application of 70% Rotary/ Shaft/ Round Kiln Alumina Calcined Bauxite Refractory Raw Material:
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 is best for making refractory insulation for Blast furnace, hot stove.
- high alumina insulating brick diatomite?brick
- Q:Who knows about ranking rules of fireproofing thermal insulation materials for exterior wall?
- You can try the following way to give a brief introduction of the fire?rating classification of external wall thermal insulation materials. 1. the building materials are divided into following categories in terms of combustion performance according to the national standard of GB8624-97. A-level： Incombustible building material: materials almost don't burn. B1-level: nonflammable building material: these materials are good at resisting flame. It is difficult for them to burst into fire when coming across open fire in the air or at high temperature. It will not quickly get wilder and when the fire source removes, it will be extinguished immediately. B2-level: Combustible building material: combustible building materials can play a certain role in flame resistance. It will immediately burst into flames when coming across open fire or at high temperature, and will lead to fire spreading, such as wooden column, timber roof truss and timber beam as well as stairs. B3-level: Inflammable building material: Inflammable building materials are highly flammable with no flame retardant ability. The fire risk is high. 2.The exterior wall thermal insulation materials can be classified according to fire rating. 1). Insulation materials with A-level combustion performance: rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2). The insulation materials with B1-level combustion performance: specially-treated extruded polystyrene board(XPS)/ specially-treated polyurethane(PU), phenolic aldehydegelatine powder polyphenyl granule,etc. 3). Insulation materials with B2-level combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane(PU), polyethylene(PE), etc.
- Q:What are the applications of refractory in petroleum?
- It can be used in chemical filler.
- Q:What kinds of fireproof materials does the safe use?
- The fireproof materials of the safe, cement foam. It is often said recently that the safes with cement inside are bad. Actually, it is not like this. Chemical means are taken to make the cement inside safes rise like a leaven dough so as to achieve good insulation. The principle is the cement foam. Fireproof safes with such techniques have good performance in terms of fireproofing and anti-theft. The manufacturing processes of this fireproof safe are highly technical, some safes with poor techniques have problems in quality. Here are some data of the foam cement.
- Q:Does hardware construction materials contain refractory?
- refractory includes one kind of building materials. It is a special material and not commonly used.
- Q:Who can introduce the external wall thermal insulation materials fire rating regulations?
- 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3 combustion performance is level B2 insulation material: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 Level A insulation material is only for fireproofing, but its thermal insulation performance is not better than organic XPS \\ EPS and other materials. I feel the best insulation materials should be modified phenolic board, which can keep insulation and fireproofing, but the unit price is very expensive. Insulation materials in the domestic market have some disadvantages, it is better to considere the materials within the acceptable range in the building needs.
- Q:The development prospect of fire-resistant material
- I also want to know, who can say, thanks all the way.
- Q:How long is the fire resistance time of the AAAfire resistance rolling shutter door?
- How long is the fire resistance time of the AAA fire resistance rolling shutter door?
- Q:What is required to do refractory material?
- But we can’t exclude that some products may contain a certain amount of metal materials: refractory material is non metallic materials whose physical and chemical properties make it suitable to be used under high temperature. Technically, it needs high purity raw material,high pressure molding, high temperature sintering to make refractory material. Refractory materials have two properties: first, the strong thermal shock resistance, second is slag resistance, the key is to look at what parts does it apply.
- Q:What is the importance of silicon powder in refractory processing?
- in amorphousness it is mainly the mobility
