1.Structure of Calcined Bauxite Description
FC Bauxite and Sic Base Water-Free Originated 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.
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. 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 usage of the Calcined Bauxite
FC Bauxite and Sic Base Water-Free Originated in China
(1) aluminium industry. Used in national defense, aerospace, automotive, electronics, chemical industry, daily necessities, etc.
(2) precision casting. Alumina clinker made after the mould precision casting processed into fine powder. Used in military industry, aerospace, communications, instrumentation, machinery and medical equipment department.
(3) is used for refractory products. High bauxite clinker refractoriness is as high as 1780, chemical stability strong, and good physical properties.
(4) aluminum silicate refractory fiber. With light weight, high temperature resistance, good thermal stability, low thermal conductivity, heat capacity is small and the advantages of resistance to mechanical shock. Used in iron and steel, nonferrous metallurgy, electronics, petroleum, chemical, aerospace, atomic energy, defense and other industries.

- Q: What are grade classifications of the external walls fireproofing material?
- 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.
- Q: What is unshaped refractory?
- Plastic. From the production method, the plastic is between the concrete and the castable. It is made of refractory material by refractory material plant, which is made of plastic clay. The ingredient is a retarder. It is packaged by plastic bag, and construction and heat treatment are carried out on the spot. But the biggest problem is the application of plastic on the knotted Jiecha easy peeling, retarder dosage improper or is vulnerable to bad caking plastic hardening.
- Q: Application of refractory materials in petroleum industry
- For example, natural gas transportation, chemicals, equipment, fillers, safety, insulation, and even building materials for housing are available.
- Q: Does the production of refractory belong to advanced technology？
- It certainly is advanced technology as it is the new material.
- Q: What are the basic requirements of continuous casting for molten steel? What are the requirements for refractory materials?
- Refractories for continuous casting is an important part of the continuous casting machine, in addition to the characteristics of general refractory material, also for the purification of molten steel and improve the steel quality, stable molten steel temperature and composition, control and regulate the flow of the molten steel and other functions, so it is called functional refractories. The above is provided by the China Technology Department
- 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: What defect does fused cast refractories have ?
- The impact on the quality of glass is mainly the defects that eroded down refractory materials mixed in the glass, thus being prodeced of grass products. Defects are mainly foreign body defects such as sand, knot and wave reinforcement.
- Q: how to classify the fireproofing material levels A1 A2 B1?
- their classification is shown specifically in Fireproof? Specification of Building Interior Decoration?Design GB 50222-95 appendix A, flammability,inflammability materials, flame retardency, noninflammability: combustion performance of A, B3, B2, B1 materials are divided into
- Q: What are the requirements for fire?rating of construction suspended ceiling material ?
- According to No. 42 ducument of department of housing construction and Ministry of Public Security: fire?rating of building suspended ceiling material should reach A level. Other civil buildings: Class A fireproofing material MCM should be set in buildings whose height is above 50 meters. National A level fireproof flexible?material is made up of soil, rock flour, sand, cement and other inorganic powder and modifying agent. Product density is 2327kg / m3. Upon examination, the combustion performance of the product meets A level requirements, and the additional classification meets s2, d0, t0 requirements. According to GB 8624-2006 sepcification, combustion performance of the product should reach A2-s2, d0, t0 level. Light, thin: 2-4mm thick / piece, saving space and cement, convenient to transport. : State Class A fireproof flexible?material. Freezing-thaw resistance: up to 100 freezing-thaw experiments (close to 100 years), the surface has no powder, no crack and no peeling. Aging and acid resistance: anti-aging property can reach more than 3500h, that is, it will not degenerate for 50 years. Recyclable: new energy, renewable , no "three wastes" emission
