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's the A class fireproof and thermal inuslation matertial for external wall?
It is roughly divided into thermal insulation mortar, phenolic foam board, rock wool board, foamed cement board, etc. Insulation mortar is quite good for its simple construction, convenience and low cost, but its production is too simple to make fake products easily. If you want to use the material, it is suggested to find a large plant with complete procedures such as provincal records of production and use, city records, test report above provincial levels, national fire inspection report, design drawings sheets of Department of Construction, etc. If there is lack of any one, it is unsafe. Hope my answer is helpful for you.
Q:How to measure the influence of high-temperature performance of the products refractory in the formation of the liquid phase.
Seeing whether it can affect the usage of the refractory material, and seeing to reduce the impurity, what's the condition of temperature of the liquid phase. Practically, whether it has any difference if you can improve, load under load and creep and reduce the impurity content. In the refractories, producing liquid are the influence of impurities, high temperature resistant strength, compared the use of the refractory material temperature: testing compressive strength after burn. If there are any impact: knowing the main crystal phase of matrix composition and content, improving the content of the main crystalline phase can improve the high temperature performance of refractory materials.
Q:Can I use ordinary cement with the addition of sand, clay, and salt as refractory material to paste the stove?
You can add some hair, sand, yellow mud and some salt, but don’t use cement, it would lead to a thermal explosion.
Q:Fire rating of decoration materials
code for fire protection design of buildings
Q:which kind of fire bulkhead is better?
I think fire bulkhead is good, fire bulkhead also known as non-combustible fire retardance board, and it's made by various incombustible material after the scientific pressing, and has good flame resisting properties, it's non-combustible time can reach over 3 hours, high mechanical strength,it has characteristics of non-explosive, water and oil resistance, good chemical corrosion resistance and non-toxic.
Q:What types does soft fire prevention materials have?
Soft type fire resistant species. Finishing fire retardant paint, component fire retardant coating, fire-resistant coating for steel structure and othe kinds of fire retardant coating. Flame retardant plastics and its products, textiles, building materials, flame retardant fabric and exterior wall thermal insulation system products, floor materials, such as various types of fire prevention materials;Fire prevention board, fire doors, fire prevention, fire shutter, fire glass window frame, elevator doors, ventilation pipes, fire blocking material, fire smoke exhaust fan and other kinds of artifacts (resistance) fire prevention.
Q:What's the A grade fireproofing material?
A grade fireproofing material: 1. fire-proof plate; 2. fireproof wooden door; 3. fireproof wooden window frame; 4. fire resisting shutter; 5. fireproof and mothproof wood; 6. fireproof glove compartment; 8. fire retardant coating; 9. fire-proof sealing material.
Q:What are grades of refractory materials?
Refractories have lots of varieties which all have different purposes.1 divided according to the level of refractoriness: ordinary refractory materials: 1580 ℃ to 1770 ℃, advanced refractories: 1770 ℃ to 2000 ℃ and super refractories: above 2000 ℃ 2, divided in accordance with shapes and sizes : Standard ones: 230mm × 113mm × 65mm, no more than four ruler.
Q:What parts of cement kilns are refractories used on?
In kilns.
Q:how about the performance of aluminum silicate fire proof thermal insulation?
aluminum silicate fire proof thermal insulation board has a good performance. it is a artificial board that separates the wood and plant fiber by mechanical and chemical methods and mixed the adhesion agent and water-proofing agent, molding by high temperature and high press. the density of fiber. tha above information is coming from the Internet and it is just for reference.
