- Q:What do we mean by saying that a ladle cover knots, elbow knots, blowpipe knots in refractory materials? What is the “knot”?
- Blowpipe is also the construction of unshaped refractory materials. Refractory material for ladle cover is light weight heat insulation refractory material. What you said that the construction of bend out refractory materials in some steel mills called "knot".
- Q:What refractories can withstand high temperature above 2100 degrees?
- Usually a dryer will not have such a high temperature. I do not know what you would use it for. Refractory cement coupled with quartz sand can work for 4 to 5 hours. So you can try cement coupled with corundum or superfine bauxite for better effect.
- Q:how to divided the external wall thermal insulation materials fire rating
- Level A: Incombustible building material is a material that does not occur any burning. Level A1: Noncombustible means no open fire. Level A2 It is noncombustible, and should measure smoke to be qualified. Level B1: Nonflammable building material: Non-flame material has good flame resistance. It is difficult to fire under the condition of open fire in the air or high temperature, and it is not easy to quickly spread, and when the combustion?source is removed, the combustion will stop immediately. Level B2: Combustible?building?materials: Flame material has a good flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as wooden column, timber roof truss, timber beam and wooden stairs. Level B3: inflammable building material has no any flame resisting effects, and is easy to burn, so the fire risk is high.
- Q:Where is refractory used? Thank you!
- Currently, refractory is widely used as inorganic nonmetallic material of production equipment lining in metallurgy, ceramics and other industries. The current definition of refractory does not only depend on whether the refractoriness is above 1,580℃.
- Q:Does anyone know about the fire resistance period of thin fireproof coatings?
- Outdoor thin steelwork fireproof coatings have a fire resistance of 2.0 hours, the thickness of coatings is between 4.5 to 5 mm, the standard amount is 5.5 to 6kg per square meter. Specific situations vary according to the thickness data provided by manufacturers . The fireproof coatings are applicable for the surface of combustible substrates, which can reduce the flammability of the surface being painted, and block the rapid spread of fire. They can be used to improve the fire resistance of the materials being painted. The fireproof coatings are coated on the substrate surfaces. They are also rustproof, waterproof, wearproof, heatproof and anticorrosive apart from flame retardant. They have good tenacity, stainability, adhesiveness, glossiness and fast-drying nature.
- Q:Selection of refractory materials?
- Inorganic non-metallic material with a refractoriness of more than 1580 degrees. Refractoriness refers to the temperature of a sample of a refractory cone, which is resistant to high temperature without softening, and does not soften and melt down. Refractory materials are associated with high temperature technology, which originated roughly from the middle of the bronze age. In the Eastern Han Dynasty has made China kiln firing porcelain material and with fireclay refractory sagger. In the early twentieth Century, refractory materials were developed towards high purity, high density and ultra high temperature products. At the same time, unshaped refractory materials and refractory fibers without firing and energy consumption were developed. With the development of modern technology, atomic energy, space technology, new energy technology, refractory material having high temperature resistance and corrosion resistance, thermal shock resistance, erosion resistance and other comprehensive excellent performance has been applied.
- Q:Urgently!! Refractory problems, online, etc.
- The service life of most refractory materials is a pair of contradictory effects. As a result, one aspect of the contradiction is porosity, and the other is volume density. The larger the volume density is, the smaller the porosity is and the more erosion resistant, but the thermal shock effect is very poor. The bigger the porosity is, the smaller the volume density is, the better the thermal shock effect is, but it is not resistant to erosion. More professionally, two curves should be made to find the intersection of the curves to adjust the recipe and production process
- Q:Introduction to refractory material
- Refractory material refers to inorganic non-metallic materials with refractoriness of no less than 1580℃. Refractoriness refers to the centigrade temperature of refractory cone sample in the case of no load when resisting high temperature without softening. But the refractoriness alone cannot descript the refractory material, thus 1580℃ is not absolute. Now refractory material is defined as material used in high temperature allowed by its chemical properties. Refractory material is widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate and power industrial area, of which the application in metallurgy accounts for the largest part of 50% ~ 60% of total output.
- Q:How to make use of waste refractory materials whose main elements are alumina and mullite?
- Crushing and pressing refractory bricks, or refractory parts . Such as welding positioner tracks use disposable tools.
- Q:Which are roofing fireproofing material?
- (1) Foamed concrete is a kind of fire-proof thermal inuslation matertial featured by good fire resistance and thermal insulation. Besides, it is also characterized by excellent sound proofing, penetration resistance, easy construction, safety and environmental protection without toxin and pollution. (2) Foam glass is featured by light weight, small heat conductivity coefficient and water absorbption, non-inflammability, fire resistance, high strength, no moulding, corrosion resistance, non-toxin and stable physical and chemical properties and thus widely used petroleum, chemical engineering and underground construction. It is also featured by thermal insualtion, heat/cold preservation and sound absorbption and thus can be used for thermal insulation of external wall and roof of civil builduing. Foam glass is featured by stable chemical property, easy to be processed and not easy to deforme, and durable. (3) With slag, basalt and other natural ore as the main raw material, rock wool, mineral wool and its products are made by high temperature melting into fiber, and then processing with binder. It has low thermal conductivity, fire resistance, easy construction and good effects of energy saving and thus is highly cost-effective. (4) With phenolic foam material as main material, phenolic resin plate is made by foaming thermoset phenolic resin. It is featured by light weight, fire resistance, no burning in the air, no smoking, non-toxin, no dropping and non-embrittlement and thus is an ideal thermal insulation material used in HAVC projects. Due to its high obturator formamen rate, low heat conductivity coefficient, good thermal insulation, water resistance and water vapor permeability, phenolic foam is an ideal thermal insulation material.
