Calcined Bauxite Grade:
1.Refractory Grade: |
Refractory grade bauxite has high refractoriness, good mechanical strength and moderate slag resistance. Bauxite in the refractory industry is typically used in ladle working lining, tundish furniture, delta sections, general perpose repairment, aluminium melting furnace and mineral processing.
3. Rotary calcined bauxite: |
Rotary Kiln Bauxite, as the name suggests, it is the bauxite produced by rotary kiln. there are three kinds of kilns for bauxite production mainly, rotary kiln, shaft kiln and round kiln.
4. Shaft kiln calcined bauxite: |
Shaft kiln bauxite, the bauxite calcined by shaft kiln. the raw material-bauxite ore is loaded from the top of kiln together with coal powder and combustion improver,the fire of calcination comes from kiln bottom, about 1300-1400 ℃After the complete calcination, the bauxite is carried out from the bottom.

- Q:Who know what kind of fire shutter fire rating are there?
- Fire resistance rating of the building elements is different due to the different requirements of the construction . Fire proof door can be divided into Serie A, B and C in terms of fire endurance limit, fire resisting limit are not should be less than 1.20h, 0.90h and 0.60h. That is, if the fire resistance rating is two, also it is possible to use a class a fire door. Hope my answer will help you.
- Q:What are fireproofing materials?
- 1. Fire-resistant coatings like finishing fire retardant paint, fire retardant coating member and fire-resistant coating for steel structure; 2. Fireproofing materials of flame-retardant plastics and plastic products, textiles, flame retardant fabrics, building materials and products, flooring materials, and wall insulation system; 3. Fireproof element of fireproof panels, fire doors, fire resistant window frames, fire resistant shutter, fire-resistant glass, elevator landing doors, ventilation ducts, fire-proof?sealing?materials, and fire protection smoke exhaust fans.
- Q:What is the concept of lightweight refractory material?
- Lightweight refractory material has high porosity, mechanical strength and erosion resistance. Compared with normal refractory bricks, it is a kind of refractory material with large volume shrinkage in high temperature, low thermal conductivity and small bulk density. It is used as thermal insulation material in industrial furnace and other thermal equipments. It has poor wear resistancel.
- Q:What are the physical properties of refractory material?
- The mechanical properties of refractory material include compressive strength, volume density and sclerosing, slag resistance, elastic modulus, thermal shock resistance, oxidation resistance, bibulous rate, fluidity, resilience, bond strength and slump, electrical conductivity, specific heat, heat capacity, the impact strength, linear change, torsional strength, stomatal aperture distribution, resistance to acid, etc. The use performance of refractory material include refractoriness, thermal emissivity, condensation, porosity, coefficient of thermal expansion. Thermal properties of refractory material include thermal conductivity, temperature conductivity, plasticity, the hydration resistance, creep performance. The physical properties of the refractory materials include structure performance, mechanical properties, shear strength, load softening temperature, CO erosion resistance. The structure properties of the refractory materials include porosity, alkali resistance and sintering. The operating performance of refractory material include consistency, tensile strength, the use performance and operating performance, wear resistance, bending strength, thermal properties.
- Q:What are the specifications of refractory kilns ?
- Since the coefficient of thermal expansion of the basic brick is large, expansion rate is about 1-1.2% under 1000 ℃ The literature indicates that: "Under the condition that the temperature was raised to 1000 ℃ and stress in brick lining is relaxed, 300N / mm2 of compressive stress can be produced, which is equals to ten times structural strength of ordinary magnesia chrome brick, six times structural strength of magnesia chrome brick, dolomite brick and spinel brick, so any basic bricks can not afford, " the paper also pointed out that " heat expansion rate of kiln body can partially compensate for expansion rate of the inner lining of 0.2% -0.4%, which is 1/3 of thermal expansion rate of ordinary magnesia-chrome brick under 1000 ℃. However, it occurs under thermal equilibrium conditions. Thereby, the kiln should be dried slowly, allowing the temperature of the kiln body to go up slowly, thus the role of compensation can be played. " This is the key to using the basic brick. " Procedures of refractory for cement kiln "( tentative one) has clearly regulated baking and cooling of the kiln in the first section of the fifth chapters. In the heating process, in particular when the temperature is in the range of 300-1000 ℃, heating rate must be less than 60 ℃ / h. This is very clear in theory but it is difficult to implement.
- Q:What refractories are accessible with ease in daily life? This material is suitable as a disposable mold and crucible for melting brass.
- Common red?brick and refractory brick.
- Q:What are included in fireproofing materials?
- Incombustible?material of construction fire-proof material Grade A: Cement, stone, steel, coat, glass, aluminium alloy, ceramic tile, etc.; nonflammable material Grade B1: Fireproof?panel, rock wool.
- Q:What substitutes are available for high-end refractories in addition to zircon sand?
- Natural ore, synthetic raw materials such as industrial synthetic mullite, etc..
- Q:Who knows the fire endurance of B-level fireproof doors and windows?
- B-grade fireproof windows refer to those fireproof windows whose fire retardant limit is not less than 1 hour. Technical requirements: I. Materials and Accessories (1) Window frame should have a certain strength to ensure the integrity and stability of the steel frame or the wood frame. (2) Steel frame and mound layer can employ galvanized?steel?sheet or stainless steel plate. Its selection criteria should be in line with the stipulation of the Article 5.1 of GB12955 "General Technical Requirements of Steel Fireproof Doors". (3) The selection standard of wood frame and mound layer should be in line with the provision of Article 5.1.1 of GB14101 "General Technical Requirements of Wooden Fireproof Doors". (4) Filling materials inside steel frame and wood frame should be non-combustible materials.
- Q:How to distinguish the fire resistant level of the rubber and plastic thermal insulation material?
- Fire?rating grading of external wall thermal insulation materials. 1, China's national standard GB8624-97 divides the combustion performance of building materials external insulation materials into the following grades. Level A: Incombustible materials: Almost no burning materials. Level B1: Incombustible materials: Flame-like material has good fire-retardant effect. In case of fire in the air or at high temperature, it is difficult to fire and doesn't spread quickly, and when the fire source is removed after combustion, it stops immediately. Level B2: Incombustible materials: Combustible materials have a certain flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily leads to the spread of fire, such as poles, wooden frame, wooden beams and wooden stairs,ect. Level B3 : Incombustible materials: No flame-retardant effect, hidhly flammable and high fire risk. 2, The external wall thermal insulation materials could be divided according to the fire?rating. 1) thermal insulation material that has the level A combustion performance: Spraying inorganic fiber, glass wool, foam glass, ceramic foam, rock wool, foam cement and perlite obturator, and so on. 2), The thermal insulation material that has level B1 combustion performance: Special processed extruded polystyrene board (XPS) / special processed polyurethane (PU), phenolic and polystyrene powder. 3), Thermal insulation materials that have level B2 combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
