Product Description:

 

Rotary and Shaft Kilin Bauxite of CNBM in China


1.Structure of 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 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:What is the use of refractory?
It is used as a protective layer inside the high-temperature, high-corrosion, high-washing, easy to be wore equipment and as an insulation layer outside equipment.
Q:Which fireproofing materials factory is the best in Xiangyang?
Of course, it is "Lvchuang Construction Energy Saving Engineering Co., Ltd." in Xuzhou, which main products are A-level fireproofing thermal insulation boards. It has many projects. B1-level fireproof materials are polyphenyl boards, extruded sheets, phenolic foam boards, Polyurethane board, sea capacity building energy efficiency module. Flame retardant has been added to the sea capacity building energy efficiency modules which has a B1-level fireproofing performance. You can also add expanded glazed hollow beads to them if you are worried about the security.
Q:How to make use of waste refractory materials whose main elements are alumina and mullite?
Crushing and pressing refractory bricks, or refractory parts . Such as welding positioner tracks use disposable tools.
Q:What kind of materials can be tested their electrical resistivity in the current refractory industry?
Graphite, Magnesium Oxide, and alumina are all feasible.
Q:How to make the service life of refractory materials longer?
Take acid resistant refractory materials as example: the atmosphere should be acidic atmosphere, if used in an environment whose temperature is 1900℃, it would exacerbate the loss of refractory materials, so don’t use overloaded. Second, select the appropriate refractory materials according to the environment. For example, if its operating temperature is 1800℃, generally speaking, the normal use of it according to the instruction of refractory materials would be fine.
Q:The performance of refractory material
The mechanical properties of refractory material include withstand voltage strength. The structure properties of the refractory materials include porosity, bulk density, such as thermal emission rate. The physical properties of the refractory materials include temperature conductivity structure performance, wear resistance, hiphotos, electrical conductivity, creep, the hydration resistance, adhesive strength.
Q:What's the A grade fireproofing material?
1. fire-proof plate; 2. fireproof wooden door; 3. fireproof wooden window frame; 4. fire resisting shutter; 5. fireproof and mothproof wood; 6. fireproof glove compartment; 8. fire retardant coating; 9. fire-proof sealing material.
Q:What is the offer of fire proofing thermal insulation material?
Asbestos fire proofing thermal insulation material Brand/Model: Xintianli Origin: Fujian|Brand: Xintianli Offer: 800.00 yuan Fire proofing thermal insulation material Brand/Model: Jiulong|Origin: Gaoxinzhuang Indutrial Park in Shucheng Town in Hejian City in Hebei Province| Brand: Jiulong Offer: 360.00 yuan. The above prices are from the Internet and for your reference only. Price may vary according to specific circumstances. I hope it can help you.
Q:Preparation of refractory clay
Is it to make refractories? Add some andalusite to the refractory mortar will improve the effect.
Q:What's the fire endurance of A grade fireproof glass curtain wall?
The following is fire endurance of A class fireproof glass curtain wall. Fire endurance of the fire window: A class fire window: no less than 1.2h; B class fire window: no less than 0.9h; C class fire window: no less than 0.6h. Technical requirements: 1. Materials and fittings: (1) Window frame should adopt the steel frame or wood frame with certain strength so as to guarantee the integrality and stability of the fitting; (2) Steel frame and mound layer can choose the galvanized steel sheet or stainless steel sheet. Its selection standard is in line with provisions of Article 5.1 in GB12955 "General Technical Requirements on Steel Fire Doors"; (3) Selection standard of wood frame and mound layer should be consistent with the provisions of Article 5.1.1 in GB14101 "General Technical Requirements on Wood Fire Doors"; (4) Filler material inside the steel frame and wood frame should be incombustible material; (5) Fireproof glass can choose the qualified product with no influence on the fire resistance test of the fire window, and its light transmittance should be no less than 75% of that of the ordinary sheet glass with the same layers; (6) Sealing material between the frame and the fireproof glass should use flame retardant material which can play the role of fire prevention and smoke insulation in case of fire. Hope it's helpful for you.
