1.Structure of Calcined Bauxite Description
High Quality Round Kiln Caldined Bauxite of CNBM in China
Bauxite (aluminous soil; Bauxite) is also called the alumina or bauxite, main ingredients are alumina, hydrated alumina containing impurities, is an earthy mineral. White or gray, brown and yellow or light red by iron. From 4 to 3.9 g/cm3 density, hardness, 1 ~ 3 is not transparent, 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
High Quality Round Kiln Caldined Bauxite of CNBM in China
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.

- Q: Preparation of refractory clay
- Is it to make refractories? Add some andalusite to the refractory mortar will improve the effect.
- Q: What kinds of fireproof and fire retardant materials are there?
- It is the fire rating.fire retardant material is not completely fireproof. It is time-limited.
- Q: I wanna ask that magnesium oxide is refractory?
- Magnesium oxide. magnesium oxide has high refractory insulation properties. After above 1000 ℃ high temperature burning, it can be transformed into crystals. And it can be transformed into dead-burned magnesium oxide or sintered magnesia oxide until rising to above 1500 ℃. It has heat-resistant, non-conductive at room temperature and relatively poor thermal conductivity. Magnesium oxide is mainly used for the preparation of ceramic, enamel, refractory crucible and refractory bricks. I hope to help you
- Q: What is the principal part of silicious refractory material
- Shenzhen Longgang Jiangyou Hua Boiler Accessories Co., Ltd. is specialized in refractory cement, refractory mortar, refractory clay, refractory aggregate and perlite. And other refractory | thermal insulation material, it has cooperated projects in Shenzhen, Huizhou, Dongguan, Guangzhou, Foshan, Zhuhai and other sites.

- Q: What are the basic requirements of continuous casting for molten steel? What are the requirements for refractory materials?
- The rapid development of the technology of continuous casting refractories so the corresponding development and improvement in variety and quality, continuous development of refractories for the continuous casting billet continuous casting production and quality have a significant impact. Especially, the completion and operation of Baosteel have greatly promoted the technological progress of refractory materials in China, and the refractory materials for continuous casting have made great progress both in variety and in quality.
- Q: whether the fire resistant level of aerated concrete building blocks can reach the grade one?
- the fire resistant level of aerated concrete building blocks can reach the grade one level. Aerated concrete strength grade shall be divided according to the concrete cubic compressive strength value. Use the symbol C and the cube compressive strength value (in N / mm2 or MPa gauge) to express. According to GB50010-2002 "concrete structure design specifications" provisions, ordinary concrete is divided into fourteen levels, namely: C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75, C80 .
- Q: How long is the fire resistance time of the AAAfire resistance rolling shutter door?
- How long is the fire resistance time of the AAA fire resistance rolling shutter door?
- Q: What materials are needed to make the amorphous refractory bricks?
- Amorphous refractory brick is composed of a certain proportion of aggregate and powder, a binder and an additive, and can be directly used without high temperature firing.
- Q: Which kind of furnace hearth refractory is better?
- hearth selected material] hearth material must be durable, high temperature resistant, general selecting masnory made of refractory cement, silicon carbide refractory products, mullite or multicrystal mullite (which is the general term of minerals composed of a series of aluminum silicate, mullite is only stable binary compound in the Al2O3-SiO2 system) etc.. [hearth] is a three-dimensional space surrounded by furnace walls for combustion of the fuel. The funtion of hearth is to ensure the fuel to burn as far as possible, and to cool the gas temperature of the hearth exit to the allowed temperature of convection heating surface safe operation . Therefore, the hearth should have sufficient space and adequate heating surface. In addition, there should be reasonable shape and size in order to fit the burner and the organize aerodynamic field inside the furnace to prevent the flame from adherence, dashing walls and have high fullness and eve wall thermal load.
- Q: Who can introduce the external wall thermal insulation materials fire rating regulations?
- According to public fire-fighting [2007] No. 182, the contents of the notification on the implementation of a number of issues of national standards GB8624-2006 "building materials and products combustion performance classification", since there is large differences between the new version of the standard GB8624-2006 and the old version of GB8624-1997 in the principle, hierarchical structure and test methods. According to the cintent of notification, in order to ensure a smooth transition between the old and new standards, the current national standard "Fireproof? Specification of Building Interior Decoration?Design" GB50222, "fire?safety?rules of tall civil buildings design" GB50045, "Fireproof? Specification of Building Design" GB50016 have not completed the relevant amendments, the new classification method of GB8624-1997 and GB8624-2006 can be used for temporary reference in terms of combustion performance of materials . From GB8624-2006 standard implementation, the classification of combustion performance is too granular, which do not match to the actual construction of the current project in our country. Therefore, the relevant departments carry on the 3rd amendment for the GB8624-2006 standards, namely GB8624-2012, and it will be released on December 31, 2012 and implemented on October 1, 2013. The combustion grading requirements in the standard: Level A is non-combustible materials (products); level B1 is nonflammable material (products); level B2 is combustible materials (products); level B3 is flammable materials (products).
