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.

- Q: Refractory net
- The development of the industry of refractory materials is very good, manufacturers are also more and more, especially in the Henan Xinmi side, next to the factory factory, we had visited gold refractory material factory, the scale is very large.
- Q: Who can tell me what is neutral refractory?
- Neutral refractories refer to the refractory materials which will not react greatly with both acidic and basic slag at high tempreratures. Such as carbon refractories and chromite refractories. The main components include carbon, silicon carbide, aluminum oxide, chromium oxide and other trivalent oxides, such as carbon refractories and chrome refractories, etc. Strictly speaking, neutral refractories refer only to the carbonaceous refractories, including carbon brick and graphite silicon carbide products, etc.
- Q: What is the fire endurance of ceramsite concrete blocks?
- What is mentioned in fire?safety?rules is that the fire endurance of 240mm thick hollow brick of ceramsite concrete is 2.9h, so 190mm thick hollow brick is 3h. B05 thickness(mm), fire endurance(h). Combustion performance 100 4.0. Non-combustible component 150 6.0200 8.0300 〉8.0B06 100 〉4.0150 〉6.0200 〉8.0300〉8.0: The fire endurance performance of building blocks wall in the table is taken from the Tianjin Construction Standard "light steam pressing aerated?concrete?block" DB / T29-128.
- Q: What's the requirements of fire-fighting criteria of heat insulating material?
- It shouldn't be under than B2 level. Roofing insulation fire rating requirements: the ministry of public security, housing and urban-rural development department issued about printing and distributing the civil building external thermal insulation system and the interim provisions on the exterior wall decorative fireproof prescribed in the notice: roof grassroots adopted duration of fire resistance is the non-combustible component that shouldn't less than 1.00 h's. Its roof insulation materials should not be below B2; Otherwise, the combustion performance of insulating material should not be below the B1 level. The junction of the roof and wall, the insulation layer around the opening part of roof should use the grade A thermal insulation material to set level fire-fighting belt that width is not less than 500 mm.
- Q: What kind of material is refractory fiber?
- Refractory fiber is good infrared radiation material with good thermal capacity and infrared heating effect. The use of firefractory fiber products can effectively save energy. It is an ideal energy-saving material. Practice has proved that using refractory fiber in continuous industrial heating furnace can save energy of over 15%, and using it in interval industrial heating furnace, it can save energy of more than 30%, while increasing productivity and improving product quality. And make the furnace structure light, large-scale with good comprehensive performance. Refractory fiber is soft and flexible and it is also ideal sealing material. As it has good insulation, sound absorption, anti-oxidation, oil and water resistance and easy construction, it is widely used in metallurgy, building materials, petroleum, chemical, shipbuilding, electric power, aerospace and other fields.
- Q: Which industry does the metallurgy and thermal insulating and refractory material belong to?
- According to "New Economic Industrial Classification", the metallurgy and the thermal insulation refractory matter belong to C category. The manufacturing industry has 30 categories. The non-metallic mineral products industry has 303 classes. The production of building materials of tiles, stones, ect. refers to clay, ceramic tile production, building stone processing, building materials produced by wastes or drogs and subcategories 3035 produced by other building materials. The manufacture of thermal and acoustic insulation materials refers to the manufactuer of mineral insulation materials and other products, like rock wool, mineral?cotton, expanded perlite and expanded vermiculite used for thermal insulation and sound insulation, but it does not include the production of 3039 subcategories, like asbestos thermal insulation and sound insulation materials, and other construction materials.
- Q: What things and cement mixed can act as refractory?
- Cement acts as cementing material. Itself works by refractory aggregate and stir the refractory material for its gelling refractory aggregate both should be fire-resistant.
- Q: What are the advantages and disadvantages of new external wall fireproof and thermal inuslation matertials?
- STP has a certain chance to self-destruct. After the sealing layer is damaged, the property will be bothered. When filling the foam glass, burst foam cement and low-strength glass fiber, the structural requirements are very high with big spraying limitations. As everyone knows that rock wool absorb organic matters, and the government do not allow us to use self-insulation, so it is not the mainstream with too low adoption rates. In fact the owners shouldn't worry about this problem. Since the developers have installed it for you, it is useless to worry about it. The other is that for those who want the original balcony closed up, if you want to shovel the original balcony wall insulation, you must pay attention to ask the construction team before you start. Because it is common that the cold bridges formed thereby will cause water seepage and moisture condensation in the balcony.
- Q: What are the material requirements of class A fire resistant door ?
- Refractory time should be no less than 1.5 hours.
- Q: What is the limit of fireproof rolling shutter?
- According to the national standard 14102-2005 GB standard, the provisions of 14102-2005 GB specify that: According to provision 14102-2005 GB: If fire resistance limit of fire resisting shutter is no less than 3 hours, it is AAA fireproof rolling shutter. Therefore, the fire resistance limit of AAA grade fireproof rolling shutter should be 3 hours.
