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.
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 are the applications of refractory?
- Refractory materials are widely used in iron and steel smelting , glass, cement kilns, non-ferrous metal metallurgy, environmental protection, and chemical, etc. For example: For a car of 1.5 tons, do you you know how much refractory it use? The answer is: To produce top hat or other steel products, glass for vehicle windows, nonferrous metals kile aluminum and copper, plastic products of the body all needs refractory. A car of 1.5 tons needs to consume a total of 10Kg refractories.
- Q:What's the classification of flameproof glass, the refractory time of fireproofing glass.
- Classify according to the structure, fireproof?performance and fire endurance of fireproofing glass. Classify according to the structure: Composite fireproofing glass (FFB) and monolithic fireproofing glass, classify according to fire resistance: thermal insulation fire-resistant glass(class A) and non-thermal insulation fire-resistant glass (class C);classify it into 5 levels according to fire endurance: 0.5 h, 1.00 h,1.50h, 2.00h, 3.00h.
- Q:How to deiron refractory?
- Our company uses magnetic separation method.
- Q:Which fire-resistant materials have good viscidity?
- Viscidity is necessary for gunning mix, repair mix and bordering. It is too broad to which has good viscidity. Both gunning mix and repair mix are powder before adding water. Bordering also has little viscidity before heating. The question shoule be more specific.
- Q:What types does refractory floor include?
- There are many types refractory bricks, including silicon aluminum refractory brick, the leading product in refractory bricks. And its high temperature resistance can reach up to 600 degree centigrade or more, so it is an excellent refractory brick. And this high-alumina refractory brick is very suitable for metal industry for its strong practicability. Another one is alkaline series refractory brick, including magnesite refractory brick, and these two bricks are good materials resistant to high temperature.
- Q:The mechanism and function of antioxidants in carbon containing composite refractories are briefly described.
- With the advantages of carbon refractories especially excellent slag resistance and high heat stability, but graphite under high temperature oxidation, in order to improve the oxidation resistance of carbon composite refractory materials, often adding a small amount of antioxidants, to improve the oxidation resistance of carbon composite refractories. Antioxidant additives commonly used in metal powder, silicon powder, magnesium powder, silicon carbide powder and so on.
- Q:What are the raw materials of refractory?
- Of course, different types have different raw materials: Magnesite (the electric?smelting: alkaline refractory, magnesia-carbon bricks, alkaline, high-purity) + crystalline flake graphite + phenolic resin + additive (silicon powder, aluminite powder, silicon carbide powder, or high-temperature asphalt,etc.) , acidic refractory: The neutral is not easy to answer. such as. You can check out the classification, such as
- Q:I know which material is the fire resistance rolling shutter door
- Fire resistance rolling shutter door and ordinary roller shutter are basically same, the differences are: Its inner and outer sides are generally made of galvanized iron sheet, filling asbestos fireproofing material betwwen two layers of fire resistance rolling shutter door, and some fire shutter doors can be interlocked with the relevant fire control system, when the breaking out of fire , it can automatically "half-drop" and "full drop".
- Q:What is the importance of silicon powder in refractory processing?
- it can certainly improve the fire resistance
- Q:What are the additives and recipes of refractory?
- Trimeric major role played bulk water reduction effect can be considered strong trimer strong bleeding effect'm sure Hey lignin sulfonate water-reducing effect of the strong retarding superplasticizer effect in two critical recommendations with more money to buy homes are equipped who is willing to disclose ah experiments to solve the problem through Chuk Wan
