Item | Calcined Bauxite High Purity of Al2O3 |
| Product Description | Calcined bauxite is one of the principal ore of aluminum. Calcined bauxite contains hydrous aluminum oxides and aluminum hydroxides, formed through the laterization of aluminous rocks in tropical and subtropical areas .calcined bauxite is obtained by calcining (heating)superior grade bauxite at high temperature (from 85OC to 1600C) .this removes moisture thereby increasing the alumina content. compared to an alumina content of about 57%to 58%in raw bauxite, calcined bauxite has an alumina content of 84%to88%.the heating is carried out in rotary kilns. |
Size | 0-1mm,1-3mm,3-5mm,200mesh,325mesh,or as buyer's request. |
| 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.( 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: Where is the production of refractory manganese alloy manufacturers? Manganese is recommended between 63 and 70!
- China is mainly used in honing, maybe I face all doubt you forget who may waste cheap no taste who cheated you don't mind set back easily stripped of a planet in the comfort of your brow you open your mouth and then grow the universe to my hand behind you let you spend what a fragile Oh maybe I face all abandoned about half past three in the morning wake up to drink a cup of soda rather baffling weary belch a bubble the tiny uneasy, and perhaps two of us Butterfly
- Q: For refractory, what is critical particle size? Thank you.
- It also refers to the largest particle size of aggregate!
- Q: How to divide the fire resistant level of EVB?
- 1. The thermal insulation material of level A combustion performance: Inorganic fiber spray coating, glass wool, foam glass, foamed ceramics, rock wool, foam cement and 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: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. I hope I can help you!
- Q: What are the characteristics of thealuminium oxide refractory?
- Physical properties of refractories include structural properties, thermal properties, mechanical properties, performance and job performance. The structural properties of refractories include porosity, bulk density, water absorption, air permeability and pore size distribution. The thermal properties of refractories include thermal conductivity, thermal expansion coefficient, specific heat, heat capacity, thermal diffusivity and thermal emission rate, ect. Mechanical properties of refractories include compressive strength, tensile strength, flexural strength, torsional strength, shear strength, impact strength, abrasion resistance, creep resistance, adhesive strength and modulus of elasticity, ect.
- Q: Fire rating of decoration materials
- code for fire protection design of buildings
- Q: what is the common materials for home fireproofing material?
- 1, lumber core 2,decoration panel 3 , plywood 4 density board 5,chipboard 6 fireproof?panel, 7.gypsum board Hope to adopt my opinion
- Q: Who knows the external wall thermal insulation materials fire rating requirements?
- The basic requirements of ratings. The design should comply with relevant state regulations and standards, the combustion performance used in exterior insulation material shouls be level A and not less than the level B2 fireproofing material. The requirements of Department of Housing and the Ministry of Public Security No. 46: Residential buildings: the height of building is greater than 100 meters, the combustion performance of insulation materials should be level A. The other civil buildings: 24≤ height
- Q: What are the best refractory materials in 2,400 Celsius degree?
- It is the purpose that decides what kind of materials you should use. What you have said is 2,400 Celsius degree, right? It is about the fire resistance of the material or the required temperature of it?
- 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: How can the furnace be replaced after the gasifier or water wall is replaced with refractory material?
- The furnace shall be made according to the type of refractory and the moisture content and the type of bond. Pay special attention to the discharge of free water and crystalline water, not too fast to prevent cracks!
