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:What things and cement mixed can act as refractory?
- This has a lot. I suggest you can check monolithic refractories.
- Q:who knows the technology of fireproofing material?
- 1, dealing mould, scrape and clean the thick liquid on the surface of mould with tin-coated steel scraper blade or plaster tool. 2, adjust laminator, according to the thickness of fireproof?panel, adjust each roller, keep them parallel. 3, ingredient, according to the requirements of recipe, stir the raw materials uniform with agitator. (usually we should add bittern firstly, stir it with modifying agent for 5 minutes, then add filler and stir for 2-3 minutes, finally add grogs and stir it to uniform) note: the stirring speed should be kept in 60-80 r/min. 4, place the cloth, place a layer of non-woven fabric and two layers of glass fiber fabric (mechanical spread fabric). 5, flitch, place the materials after compounding and stirring into stop gauge of laminator, then you can start up and produce continuously, it's finished product after finishing. note: the distance between two templates is 2-4mm.
- Q:What are the specifications of fireclay bricks?
- 1. The various classification criteria of clay bricks. First, according to the physical and chemical indicators, they can be divided into these types: (NZ) -42, (NZ) -40, (NZ) -38. Second, the classification of specifications of clay bricks is in line with the stipulations in "general shape and size of refractory bricks". Finally, according to the stipulations of relevant state departments, the clay bricks can be divided into standard bricks, ordinary bricks, special-shaped bricks, special bricks. Second, level of refractory temperature of refractory bricks The refractoriness of refractory bricks is divided into four levels according to changes of alumina content. We know that the components in clay bricks include Al2O3. Alkali metals are also included. The refractoriness of AAA-level clay bricks in Ruitai Refractory Material Factory is 1750 ℃; A-level bricks is 1730 ℃; B-level bricks is 1670 ℃; and C-level bricks is 1580 ℃. The softening temperature under a fixed load of Clay bricks is about 1350 ℃. Clay bricks, also known as sintered bricks, are small size artificial bricks for modern architecture. Clay bricks have good properties and high thermal stability, in which Fe2O3 content is less than 2.0 to 2.5%. Overall dimensions: 230 * 115 * 65mm
- Q:Is there vermiculite in refractory?
- Vermiculite is usually used as lightweight material in refractory field, and its volume density is about 0.5.
- Q:What are some of the new refractories and what are their characteristics?
- Refractory common AZS refractories are often used brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, aluminum oxide, beryllium oxide and other refractory materials, Magnesium Oxide
- Q:What are the requirements of the performances of brasque refractory?
- Physical properties of refractory include structural properties, thermal properties, mechanical properties, usability and operation property. The selection of the brasque refractory must have the following characteristics: 1. properties of not distortion and not melting at sufficient temperatures 2. have the necessary structural strength at high temperatures and does not soften and deform 3. must keep stable volume at high temperatures and will notcrack caused by expansion and contraction 4. will not rapture and flake when temperature is drasticly changed or heated unevenly 5. resistant to chemical erosion of metallic solution, slag and furnace gas, etc.
- Q:How much is the content of boron carbide in refractory material?
- Is it available to iron materials?. Answer: It can be applied to all products, what you need is just a general proportion. Nevertheless, you’d better tell me what product it is exactly.
- Q:How long is the fire-fighting time of A class fire resisting window?
- Fire resisting window' duration of fire resistance: A class window, fire insulation ≥1.50h and fire resistance integrity ≥1.50h. Fire resisting window can be divided into three kinds: 一. window frame and sash framework adopt fire resisting window with steel manufacture ; 二. window frame and sash framework adopt fire resisting window with wooden manufacture; 三. window frame adopt steel and sash adopt wooden material or window frame adopt wooden material and sash framework adopt fire resisting window with steel material.
- Q:What's the fire resistance rating of the exterior fire?retardant?coating?
- Exterior thick fire-resistant coating for steel structure can reach the first level of fire resistance, thin fire-resistant coating for steel structure can be fire-resistant for three hours, and ultra-thin fire-resistant coating for steel structure can just be within the second level of fire resistance.
- Q:What kind of material is good for cabinet fireproof board
- What kind of material is good for cabinet fireproof board What are the advantages and disadvantages of using it? How much is the price? A about how much does one piece cost?
