Usage/Applications of Calcined Bauxite Rotary Kiln Al2O3 85%:
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.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's the standard of fireproofing material?
- Class A1 is divided according to the combustion performance of GB8624-2006 building materials and products. Specific technical index requirements are: 1, the temperature rise ≤30 degrees;mass loss rate ≤50%; combustion duration time is 0; 2, main components, overall products, gross calorific value of external secondary components ≤2.0MJ/kg; any inner secondary component ≤1.4MJ/kg; (there are difference between homogeneous and non-homogeneous). Z802 building materials noninflammability testing furnace has to be used for testing technical indicators mentioned in test 1, using Z805 building materials combustion heat value to test technical indicators mentioned in test device 2.
- Q: Which company needs the new refractories?
- The power plants are mainly used in steel plant, lime kiln, coking plants, boilers, etc. I will try my best to answer what I can. There are too many glassworks. You can tell me more anout what you need. As long as there is a large kiln business, the refractories and aluminum manufacturer are needed.
- Q: What is the upper temperature limit for refractory materials?
- The key depends on what refractories you use
- Q: How about the prospect of refractory material?
- Area depends the market. Resource-based industry
- Q: What's the requirements of fire-fighting criteria of heat insulating material?
- It shouldn't be under than B2 level. Roofing insulation fire rating requirements: the ministry of public security, housing and urban-rural development department issued about printing and distributing the civil building external thermal insulation system and the interim provisions on the exterior wall decorative fireproof prescribed in the notice: roof grassroots adopted duration of fire resistance is the non-combustible component that shouldn't less than 1.00 h's. Its roof insulation materials should not be below B2; Otherwise, the combustion performance of insulating material should not be below the B1 level. The junction of the roof and wall, the insulation layer around the opening part of roof should use the grade A thermal insulation material to set level fire-fighting belt that width is not less than 500 mm.
- Q: Does anyone know about the fire resistance period of thin fireproof coatings?
- The columns are 2.5 to 3.0 hours, beams are 2.5 hours, C-shaped steels are 0.5 hours. The thin steelwork fireproof coatings are primarily water-soluble, which will be expanded and foamed when exposing to the fire. Thus the fire-resistant insulation layer formed through expansion and foaming will delay the temperature increase of the steel and protect of steel components. The thin fireproof coatings are made of adhesives, catalysts, carburizers, foamers, fillers, fibers and modifiers. The required emulsion polymers must have good adhesion, durability, and water-resistance to the steel substrates. The coating has a strong adhesion and good flexibility, is light and thin, as well as highly resistant to vibration. It is especially applicable for indoor bareness steel structure, light layer steel structure, and steel structure with decoration demands whose fire resistance requirement is within 1.5-2.5 hours.
- Q: What are the requirements for the performance of refractory materials?
- Performance requirements for electric furnace lining refractory: 1, sufficient refractoriness and softening point. Because of eletric arc, the inner surface temperature of lining can be as high as 1500 to 1800 degree. 2, strong resistance to slag. Because the dust penetrate into the furnace through pore lining, and the refractory material subject to loss, leading to spalling. 3, good thermal and shock resistance. Because during steelmaking, opening door and lifting of the furnace will lead to sudden changes in the temperature of the furnace lining refractory material, so spalling and cracking may occur, damaging the lining premature. 4, enough strength, because the lining is impact during charging, tilted when vibration,and eroded by metal, slag and airflow. 5, the thermal conductivity shall be small, and the conductivity shall be low. The commonly used furnace refractories are dolomite brick, magnesia brick, high alumina brick, silica brick and magnesia ramming etc.. Because of different working conditions of the various parts of the furnace, the refractory materials are not the same.
- Q: Can anyone tell me what is a high alumina refractory?
- High alumina refractories: High-alumina refractory products have high refractoriness, compressive strength and refractoriness under load, which are used for building the high-temperature parts of various large blast furnaces, such steelmaking furnace, airheater, electric furnace, rotary?kiln and other thermal equipment.
- Q: What are the material requirements of class A fire resistant door ?
- It must meet standards of the national regulation. You may search on Baidu.
- Q: Is it necessary for the frame of glass fireproof door to be crammed with fire-proof material?
- 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.
