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: Does anyone know the characteristics of refractory for glass kiln?
- The characteristics of refractory for glass kiln: First, it can well resist the erosion of glass?fusant and gas actor, and has sufficiently high load softening temperature and thermal stability. Usually we hope the refractories of all parts of the furnace will has no partial early erosion phenomenon to ensure that the entire furnace has a sufficiently long service life. However, due to the different mechanical, physical and chemical conditions of different parts of glass furnace, the performance of refractories should adapt to the glass furnace thereto and at the same time has no adverse effect on the adjacent other kinds of brick materials. Besides, we should consider the price of brick material, we should try to consider using commonly used stereotypes bricks of standard sizes which is cheap and quickly supplied by the warehouse. The damage of glass melting furnace lining is mainly due to chemical erosion, assisted by thermal stress. The degree and speed of chemical erosion is closely related to the applied parts, furnace temperature and melting glass varieties, and of course, the quality of the lining itself is also crucial. The nature of refractories using in the glass furnace has a very significant impact on the operation of glass melting furnace and the quality of glass. The application of poor main beam refractories will not only cause frequent shutdown for maintenance, limiting melting temperature, lowering furnace output, but also shorten the life of the furnace, and make glass has a variety of defects (stripes, stones, etc.), lower the quality of the glass. Here are the description of the nature and purpose of commonly used refractory in glass furnace.
- Q: What is the upper temperature limit for refractory materials?
- The key depends on what refractories you use
- Q: What are the models of refractory cables?
- NH is the firat letter of "refractory" in Chinese phonetic alphabet; It is V, not W. PVC insulation and sheath; K in KVV represents the control cable. 5 * 10 represents the cable is made up of 5 core cables whose nominal cross section is 10 square milimeter.
- Q: Do you know the refractories?
- Alkaline material products: MgO, CaO based crystalline phase, because MgO and CaO are alkaline earth oxides, so it is called alkaline refractory. Their high melting point, alkali resistance slag (C/S > 2) corrosion ability is strong, belong to advanced refractory materials, but they are easy to hydration. Magnesia chrome brick, dolomite brick, brick olive and other products, the main chemical composition is MgO, CaO China also belongs to alkaline materials.
- Q: What are the construction measures of refractory material in winter? Please descriptive briefly.
- Binding agent should be attaced great importance to when construction is conducted in winter. Generally if the bingding agent is water or cement, antifreezing measures should be taken.
- Q: What is fireproofing material? Are fireproof materials the same thing with thermal insulation materials and refractories?
- The refractory material is capable of withstanding high temperature burning, while fireproofing material is to prevent burning. They are different from each other
- Q: The performance of refractory material
- As for easticity modulus, you can serach for information on the Internet or specialized books.
- Q: how to classify Insulating Refractory ?
- General materials have test reports, where fire rating is labled.
- Q: Does refractory belong to metallurgical auxiliary materials?
- Refractory is widely used in industrial circle, such as metallurgy, chemical industry, petroleum, mechanical manufacturing, silicate and power, and its coonsumption is the maximum in metallurgy, accounting for 50% to 60% in total output. In order to improve slag-corrosion resistance of furnace lining, usually choose carbon-containing refractory. Refractory of various furnace lining are respectively: For the body, it is clay brick; as for the lower part, bosh and middle, it is SiC brick; for furnace bottom, it is carbon brick. Lattice brick is an important refractory product used in air heating furnace and regenerative chamber. Refractory is widely used in metallurgy. In order to improve slag-corrosion resistance of lining. Central line in tuyere and hearth are high-alumina brick. Refractory consumption is the maximum in metallurgy, accounting for 50% to 60% in total output. For the bosh and middle, it is SiC brick. In order to improve its thermal storage capacity: The furnace stack is clay brick. It is defined as refractory where the physical and chemical properties allows its use in high temperature environments; The lower furnace body
- Q: How to divide the fire resistant level of construction thermal insulation materials?
- How to divide the fire resistant level of construction thermal insulation materials: Combining three versions of GB8624 (1997,2006,2011) external wall thermal insulation fire?rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indexes for specific division, very professional and technical, so it is hard to say clear now. For details, please contact Qingdao Shanfang Instrument Company who is specialized in fire?rating tester for external wall thermal insulation materials.
