- Q: what kind of refractories is used to make the industrial silicon furnace mouth long life?
- Fused zirconia corundum brick, the smelter of the glassworks is used this kind of lining, and you can contact by private letter.
- Q: Can anyone tell me the requirements of the refractory masonry?？
- Refractory materials actually have two functions. The first one is to improve the refractoriness and the second one is to improve the body plasticity of refractory materials.The higher the aluminum content is, the better refractory it will be. Of course, the content of aluminum in refractory materials can not be impoved only by using kaolin. Such raw materials that contain more aluminum as bauxite chamotte should be used as framework.So the content of aluminum in kaolin does not need to be too high and more than 38% of aluminum is enough. However, the viscosity should be taken into account. It will be better if the viscosity is better as the extra bentonite do not need to be added.The refractoriness that is is above 1400 degree is enough.
- Q: How to divide the materials according to the National Fireproofing Material Standard?
- according to China's national standard GB8624-97, the combustion performance of construction materials can be divided into several classes: Class A: Incombustible building material: Almost no burning material. Class B1: nonflammable building material: nonflammable material has a good flame resistance effect. when it meet the open fire in the air or burnd at high temperature, it is difficult to spread quickly, and when the fire source is removed, the combustion stop immediately. Class B2: flammable building material: flammable material has a good flame resistance effect. when it meets open fire in the air or at high temperature, it will immediately burst into flames and easily cause fire spread, such as wooden column, timber roof truss, timber beam, and wooden stairs,ect.. Class B3: inflammable building material: No flame resisting effects, highly flammable, high fire risk.
- 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: How many refractory materials does the annual output of 1 million tons of coke oven require?
- Refractory material is an important material used in iron and steel industry, it is mainly used in steel-making furnace, furnace lining, loading and transportation of metal and slag ladle lining, the furnace lining procedure of billet heating, heat conduction and lining of blast furnace and the flue. So, to put it simply, we can think of it as a structural material, which can withstand a temperature of 260-1760 degrees centigrade.
- Q: How to divide the fire rating standards of insulation materials?
- The fire rating classification standards of insulation materials, 1. Insulation materials with A-level combustion performance: inorganic fiber spraying, rock wool, glass wool, foam glass, ceramic foam, foam cement, close-celled perlite, etc. 2. Insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), Phenolics, Polystyrene rubber powder particles,etc. 3. Insulation materials with B2-level combustion performance: Expanded polystyrene sheets(EPS), Extruded polystyrene board(XPS), Polyurethane(PU), Polyethylene(PE), etc.
- Q: How long is the duration of fire resistance that fireproof door of level B can endure?
- Level B refers to the fire resistance rating and different hours in fireproofing of the fireproof door. Fireproof door of level A can endure fire for 1.5 hours while level B 1.2 hours
- Q: what is the Specifications Grading for Fireproof rubber insulation materials ?
- At present, China Building Materials has two grading criteria for combustion performance. "Combustion Performance Classification Method of Building Materials" and "Combustion Performance Classification Method of Building Materials and Products" (GB8624-2006). Among them, one of the major changes of GB8624-2006 and GB8624-1997 is to divide the material combustion performance grading from homogenous material)Class A (composite sandwich material), B1, B2 and B3 level five minutes as A1, A2, B, C, D, E, F seven levels.
- Q: what's the detailed address of fireproof and thermal inuslation matertial market?
- Detailed address of fire insulation materials market is as follows: A: Guangzhou Huatai building materials co., LTD. Address: Guangzhou Tianhe Chepo Road no. 10 B: Address of Donglong building materials market: Guangzhou Tianhe Taian North Road no. 7 C: Address of Huiya building materials trade market : Guangzhou Tianhe Sports West Road No. 109
- Q: How many levels are there in the classification of PP fireproof materials?
- The level of fireproof materials: A-level: Non-combustible building materials have rare chance to burn. A1-level: Non-combustible materials, no open fire A2-level: Non-combustible materials, smoke should be tested and qualified. B1-level: Fire-retardant building materials: Fire-retardant materials are good at resisting flame. It is difficult for them to burst into fire when coming across open fire in the air or at high temperature. It will not quickly get wilder and when the fire source removes, it will be extinguished immediately. B2-level: Combustible building materials: Combustible building materials can play a certain role in preventing combustion. It will immediately burst into flames when coming across open fire or at high temperature, and will lead to fire spreading, such as wooden pillars, roof frames and beams as well as stairs. B3-level: Inflammable building materials are highly flammable with no flame retardant ability, fire risk is high.
