1.Structure of Calcined Bauxite 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 can 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 75% to 90%.
2.Main Features of the 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.

- Q:Please answer the questions about the packing and transportation requirements of refractory materials.. Requirements for packing of refractory bricks
- Bricks are usually made from pallets.Generally take the automotive, coastal sea city.
- Q:Is it normal for caable fire resistant material to catch on fire?
- Abnormal, preventive measures: 1 take fire preventive measures. Measures taken for fire retardant measures of cable: (1) seal closely with fire resistant materials holes ran by cables through walls, shafts to prevent the cable fire, high temperature gas diffusion and spread when cables are on fire. (2) to wrap the cable with the insulation refractory material, when the cable is surrounded with fire, warpped cable is insulated by the insulation material from fire, so it will not be burned. If the cable itself is on fire, fire will be extinguished thankes to lack of oxygen in warpped cable, to avoid the fire to spread out. 2 to strengthen the cable circuit switch and regular protective check and maintenance, to ensure that the action is reliable. 3 to strengthen the cable operation and monitoring, to avoid the overload of the cable operation. . 4 regularly clean dust on the cable, to prevent cable from catching on fire due to the accumulation of dust. 5 to ensure the construction quality, the quality the cable must be strictly in line with the requirements and standards. 6 cable laying should maintain enough distance form the heat pipe, control cable is no longer than 0.5 meters; power cable is no longer than l meters. Control cable and power cable should be divided into slots, be layered and seperated instead of being overlapped . For the parts that do not meet the requirements, measures must be taken to insulate heat and fire. 7 regularly teat cable , abnormal problem should be handled in a timely manner. 8 install fire alarm so that fire will be discovered on time, and cables will not catch on fire. 9 the cable trench should be kept dry to prevent the cable from being affected with damp, or leading to declined insulating function and short circuit.
- Q:What is the upper temperature limit for refractory materials?
- Different materials are different. In the professional field, there is a triangulation cone softening point experiment as a reference for using the upper temperature limit.

- Q:How can refractory material of the electric furnace be used for longer.
- Key: 1, consider the furnace size; As furnace volume differs, pressure of liquid iron (steel) on the crucible wall lining will not the same; 2, consider melting steel type: If different steels are melt, the erosion of steel liquid on the lining refractory is not the same; 3, give full consideration to the lining of the grain size distribution of the refractory material, otherwise, it will cause of refractory matrix size segregation. 4, regardless of the kind of refractory materials, take full consideration into the mineral phrase of refractory material, high temperature and other equal factors. 2011 - 01 - 05 Guangyi mineral
- Q:Are the rubber insulation materials are refractory materials?
- Bushi
- Q:Which are roofing fireproofing material?
- (1) Foamed concrete is a kind of fire-proof thermal inuslation matertial featured by good fire resistance and thermal insulation. Besides, it is also characterized by excellent sound proofing, penetration resistance, easy construction, safety and environmental protection without toxin and pollution. (2) Foam glass is featured by light weight, small heat conductivity coefficient and water absorbption, non-inflammability, fire resistance, high strength, no moulding, corrosion resistance, non-toxin and stable physical and chemical properties and thus widely used petroleum, chemical engineering and underground construction. It is also featured by thermal insualtion, heat/cold preservation and sound absorbption and thus can be used for thermal insulation of external wall and roof of civil builduing. Foam glass is featured by stable chemical property, easy to be processed and not easy to deforme, and durable. (3) With slag, basalt and other natural ore as the main raw material, rock wool, mineral wool and its products are made by high temperature melting into fiber, and then processing with binder. It has low thermal conductivity, fire resistance, easy construction and good effects of energy saving and thus is highly cost-effective. (4) With phenolic foam material as main material, phenolic resin plate is made by foaming thermoset phenolic resin. It is featured by light weight, fire resistance, no burning in the air, no smoking, non-toxin, no dropping and non-embrittlement and thus is an ideal thermal insulation material used in HAVC projects. Due to its high obturator formamen rate, low heat conductivity coefficient, good thermal insulation, water resistance and water vapor permeability, phenolic foam is an ideal thermal insulation material.
