3. 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: What is the common inorganic fireproof and thermal inuslation matertial?
- Ceramic foam insulation board is made from clay tailings, ceramic broken flake and river silt, which is the closed ceramics material with high porosity roasted in high temperature by advanced production technology and foam technology. Products have fire retardant, small deformation coefficient, aging resistance, stable performance, good environmental protection, good compatibility between wall base and plastering layer, good safety and soundness and a lifetime as long as the building itself.
- Q: Who knows what is the standard of insulation material whose fire proof is level A?
- Non combustible materials of level A: WW inorganic active wall thermal insulation material, Cement foaming thermal insulation board, Glazed hollow bead insulation mortar, rock wool board, Glass wool board, Foam ceramic.Non combustible materials of level A, endowed with low density, low thermal conductivity, higher bearing capacity, convenient construction , economy and durability, are widely used in heat pipe, heat equipment, other industrial pipeline equipment , thermal insulating materials on industrial buildings, and used as heat preservation, thermal insulation, sound absorption materials of industrial and civic buildings.Non combustible materials of level A are used more for refractory protection coating material of steel structure because of its good thermal stability.
- Q: Physical and chemical indicators of various refractory.
- it depends on what it is for. There are thousands of kinds of refracroties. You should just ask what you need.
- Q: The effect of a high content of water in liquid resin exerted on refractory material?
- For one thing, Substandard whiteness, transportation, low quality and the storage of refractory material may account for this. For another, a high content of moisture reduced the performance of refractory material. A high content of moisture is equal to buy water with same money in terms of trade settlement. Based on this, we can’t consider the super-standard water content from a single aspect, because the water content in refractory material is definitely super-standard, and another problem is particle size. Many people hold the idea that excessive amount of water content may revive its original performance, but it tends to have influenced the quality of refractory material.
- Q: Who knows the external wall thermal insulation materials fire rating requirements?
- The basic requirements of ratings. The design should comply with relevant state regulations and standards, the combustion performance used in exterior insulation material shouls be level A and not less than the level B2 fireproofing material. The requirements of Department of Housing and the Ministry of Public Security No. 46: Residential buildings: the height of building is greater than 100 meters, the combustion performance of insulation materials should be level A. The other civil buildings: 24≤ height
- 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: Could you tell me how does fire protection standard of decorative material is divided?
- Level of fire prevention materials: A grade: non-combustibility building material, almost without burning materials. A1 level: non-combustible, no flame A2, non-combustible, to measure smoke, to be qualified. B1 level: flame retardant building materials: flame retardant materials has good flame retardant effect. It is uneasy to burn when encountering open fire in the air or under high temperature and is not easy to quickly spread, and when the fire source move, it will stop burning immediately. B2 level: combustibility building materials: combustibility materials has good flame retardant effect. It will immediately burst into flames when encountering open fire in the air or under high temperature. It easily leads to the spread of fire, such as timber, wooden frame, wooden beams and wooden stairs. B3 level: flammable building materials, without any flame retardant effect, easy to burn, and with a very high fire risk.
- Q: Classification of porosities in refractories and their effects on properties
- Effect of apparent porosity on properties:The porosity is high, the volume density is low, the structure become more loose, generally low strength, corrosion resistance worse (slag infiltration and erosion along the hole toward the inside), but to improve the thermal shock resistance (resistance to thermal shock and not damaged).
- Q: What are the new refractories?
- Most are ordinary refractories.
- Q: Is it necessary for the frame of glass fireproof door to be crammed with fire-proof material?
- Close the door , and check if the gap is normal, whether the hole and the door leaf are in the same plane, and whether the door leaf has tendency to fall down. Fire resistance steel door——means that use a cold rolled steel sheet as door frame, door plank and framework, and stuff a door leaf with incombustible material.
