Q: How to divide fire rating of decorating materials ?: level A: incombustible, B1: Flame retardant, Level B2: combustible, Level B3: Flammable.

Q: How can refractory material of the electric furnace be used for longer.: I do not know if you are referring to super high power arc furnace for steelmaking, if you are, I have a easy solution for I have been doing this work.

Q: What are the applications of refractory?: Refractory materials are widely used in iron and steel smelting , glass, cement kilns, non-ferrous metal metallurgy, environmental protection, and chemical, etc. For example: For a car of 1.5 tons, do you you know how much refractory it use? The answer is: To produce top hat or other steel products, glass for vehicle windows, nonferrous metals kile aluminum and copper, plastic products of the body all needs refractory. A car of 1.5 tons needs to consume a total of 10Kg refractories.

Q: What kind of refractory materials can withstand 1500℃ when processing briquette stove core and meanwhile cost less?: Alkali resistant castables cost the least.

Q: Which schools are the best schools in the world for learning knowledge about refractories?: If you search on a worldwide scale, I might say you are ambitious!!! This major becomes an unpopular one and you must have to embark on graduate and PhD to specialize in it provided that you want to go abroad for further study. Wuhan University of Science and Technology may be the best school in this field with its close relatinship with many refractory manufacture factories across the country. Henan University of Science and Technology is also advisable in terms of this major, which probably promise you a job. Other universities in this regard are not quite familiar to me. You raised these questions, which shows that you are a layman to this major or not quite familiar with this major. If you have any questions, you can resort to me if I can.

Q: Who can introduce the external wall thermal insulation materials fire rating regulations?: External wall thermal insulation materials fire rating regulations, 1, the height of a building is greater than or equal to 100m , the combustion performance of insulation materials should be level A; 2, the height of a building is greater than or equal to 60m but less than 100m, the combustion performance of insulation materials should not be less than the level B2. When using level B2 thermal insulation material, every layer should set horizontal fire barrier zone 3,The height of building is be equal or greater than 24m but less than 60m, the combustion performance of thermal insulation material should not be less than the level B2. When using level B2 insulation material, each two-layer should set fire barrier zone ; 4, the height of building is less than 24m, the combustion performance of insulation materials should not be less than the level B2. Besides, when using level B2 thermal insulation material, each three-layer should set a horizontal fire barrier zone.

Q: Which one is better, fire-resistant wood or steel?: According to my understanding. This fire-resisting wood is better. Iron birch. The iron birch is three times harder than the oak, twice as hard than ordinary steel. It is the world's hardest wood which is used as a substitute for metal. The Soviet Union have used iron birch for the manufacturing of roller ball, bearings and it is applied in yachts. Iron birch has some wonderful characteristics. Since it has very dense texture, once put in the water it will sink; even if it is soaked in the water for a long time, the inside still remains dry. The iron birch is twice harder than the steel, it doesn't mean that its hrc value is twice of that of the steel. HRC means test load 1471.1N (150KG-F) using a diamond cone head with the point angle of 120 degrees to press. The calculation formula HR= (K-H) /C,K=0.2MM,H is the depth of indentation after releasing the major load. C= 0.002MM, so HRC100 is a limit value, then H is 0, which means that even the diamond will not drill into it. Generally the hardness of bearing steel is about HRC60. Iron birch is the championship among trees in terms of hardness. The bullet hit the wood is like hitting on a thick steel plate and the wood will be motionless. So, it is known as a tree harder than steel. I hope my answer will be helpful to you.

Q: What are the fireproofing materials of the external wall included?: Facades a fireproof material comprises three anti-cloth, fireproof cloth, plastic cloth, PVC tarpaulins, flame retardant cloth, Hair Dryers cloth, automobile tarpaulin, PVC three anti-cloth, the freight yard covered cloth, PVC coated fabric, canvas industry etc., are widely used in automobile canopy cover cloth, trains cover cloth, ships cover cloth, cloth covered open-air yard, industrial and agricultural fields; used in glass, timber, fertilizer plants, steel plants, machinery metal factory, feed mill, grain storage, container plants, oil refineries, packaging plants, paper plants, air conditioning plants, logistics, ore factory, fleet, rail, sea and so hoping to help you

Q: The manufacturing technique of refractory material: The major components of alkaline refractory material include magnesium oxide and calcium oxide. The commonly used alkaline refractory material is magnesia bricks. The magnesia bricks with 80%～85% magnesium oxide has good resistance to basic slag and slag and higher refractoriness than clay bricks and silica bricks. It is mainly used in open hearth, oxygen blowing of converter, electric furnace and smelting non-ferrous metal equipment and other high temperature equipment. Refractory materials applied on special occasions include high temperature oxide refractory materials such as alumina, lanthanum oxide, beryllium oxide, calcium oxide, zirconium oxide, etc., refractory compounds such as carbide, nitride, boride, silicide and sulfide, etc., and high temperature composite materials, including metal ceramics, high temperature inorganic coating and fiber reinforced ceramics, etc. Consult and find reference for efractory materials production equipment, go to http://hi.baidu.

Q: What are the grades of refractory exterior wall thermal insulation materials?: Classification of fire rating of extrior thermal insulation materials 1, According to national standard GB8624-97, the combustion performance of building materials are divided into the following grades A level: Incombustible building materials: Materials hardly burn. B1 class: Flame-retardant building materials: Flame-retardant material has good flame resistance. In case of fire in the air or at high temperature, it is difficult to catch fire and the fire will not spread quickly. And when the combustion source is removed, the burning will stop immediately. B2 Class: Combustible building materials: Combustible materials have a certain flame retardancy. In case of fire in the air or at high temperature, it will immediately burst into flames and it is easily to spread fire, such as wooden column, wooden roof truss, wooden beams and wooden stairs, etc. B3 level: Inflammable building materials: It has no flame retardant effect, and it is extremely inflammable, and the risk of fire is high. Classification of exterior wall thermal insulation materials according to fire rating: 1. Thermal insulation materials with A-level combustion performance Rock wool, glass wool, foam glass, foamed ceramic, foam cement, hole-closed perlite, etc. 2, Thermal insulation materials with B1-level combustion performance: Extruded polystyrene board (XPS) after special treatment / polyurethane (PU) after special treatment, phenolic aldehyde, gelatine powder polystyrene granule, and etc. 3. Thermal insulation materials with B2-level combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
