1.Calcined Bauxite 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.
2.Main Features of Calcined Bauxite
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 there. By 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.
3.Main usages of Calcined Bauxite
1. aluminium industry.
2 . precision casting.
3. for refractory products.
4. aluminum silicate refractory fiber.
5. with magnesia and bauxite clinker as raw material, add appropriate binder, used for pouring ladle whole ladle lining has particularly good effects.
6. manufacture alumina cement, abrasive materials, ceramic industry and chemical industry of aluminum compounds

- Q: What is refractory brick?
- Capability1. Refractory brick is also known as firebrick. It is faint?yellow or brownish. Refractory brick with 770 ℃ at high temperatures is called for short firebrick. It is mainly used for building and smelting furnace. It is a refractory material made by fring refractory clay or other refractory material.
- Q: What are the new refractories? What are the features? How about their application and development?
- In metallurgy, in what position should it be used, in order to make the best. Answers are as following. In iron, steelmaking or converter. When questioning, pay attention to the ways. Answers: Try to use synthetic refractory materials.
- Q: What kind of refractory materials are used in metallurgy industry?
- Argon-blowing rod, siliceous dry vibrating materials, desulfurizer, slag-stopping ball, stainless steel thermal insulating agent with high efficiency, dry vibration material, sizing nozzle heat-insulating panel, chrome refractory , refractory carstables for ladles, magnesia carbon refractory, package castable, siliceous drainage agent, tundish block, iron trough, deoxidizer, compound deoxidizer,silicon manganese alloy , stemming, floating plug,slagging agent. The main materials are as follows: recarburizer, covering agent, intermediate frequency furnace burden, mould fluxes, insulation thin slag agent, skimmer repair material, joint sealant.
- Q: What dose the fireproof and thermal insulation material include?
- Currently the non-combustible insulation materials for external insulation system mainly are foam insulation board, composite cement foam insulation board, aerated concrete panels, rock wool board (strip), and inorganic insulation materials. 1. foam insulation board refers to foam ceramic insulation panels whose raw material is inorganic ceramic which is calcinated at high temperature with abbreviation of ceramic insulation board 2.Composite cement foam insulation board is a hydrophobic lightweight closed-cell insulation board whose main materials are cement, fly Ash, and silica fume which has been foamed, cured and cut. 3. aerated concrete panel is a lightweight concrete panel which has been autoclaved with lightweight materials, siliceous material and gas former as its raw materials. 4. rock wool panel, with natural igneous rock wool as its main raw material, is a cotton which is melted in high temperature by centrifugation and is pasted by thermosetting resin.
- Q: What are the characteristics of the carbon composite refractories?
- The features of carbon composite refractories: 1. It is with an aggressive high thermal shock resistance 2. Good resistance to molten steel and slag
- Q: What is the appropiate thickness if fire resistant time for ultra thin steel structure coating is 2.5 hours?
- A level fire resistant steel structure building steel column cannot be constructed with super thin steel structure fire retardant coating, because the ultra thin steel structure fire retardant limit is less than 3 hours. Thin fire retardant coating for steel structure is water borne fireproof coatings painted on the surface of steel structure. It will form carbonized fireproof heat insulation protective layer to insulate oxygen and delay the speed of heating steel structure when it catches on fire, avioding the rapid temperature rise of steel structure and increasing its fire resistant limit. Fire resistance performance: The 2mm coating ≥ 60min, 3mm 100min.
- Q: What's the material of fireproof and wear-resisting floor?
- Hello! Fireproof floor is non-flammable, wear resistant, and beautiful. It is made by construction steps and has many advantages: seamless, environment friendly, non-toxic, resistant to abrasion and corrosion, waterproof, dustproof, beautiful in appearance with integriality and no irritating odor The material of fireproof floor is in the form of liquid which will be in the shape of solid membrane after the completion of construction. It can be widely applied to the ground in the factory, residential ground or walls, and large areas like institutions and warehouses with high requirement on fire prevention. It can also be used in the field with no requirement on fire protection for it is beautiful in apperance and just like epoxy floor, and with good cost performance, it is a kind of commonly used decorative material. Hope it's helpful for you!
- 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: I wanna ask about the thermal insulation material fire resistant level?
- 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, 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: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 Level A insulation material is only for fireproofing, but its thermal insulation performance is not better than organic XPS \\ EPS and other materials. Thanks
- Q: Who knows what fire heat preservation material are there?
- Organic material, polystyrene board, plastic extruded board, phenolic resin. Sea capacity module (fire insulation materials fire performance can reach the B1 level, thermal conductivity is only 0.028w\m - K is a good choice, class A fireproof materials now is the mainstream rock wool (mineral wool is wool). A1 fire resistance The largest manufacturer is Thai stone rock wool Co. Ltd.
