- Q: What materials is silicious thermal insulation board made of?
- Siliceous insulating panels use quartz sand as the main material and are composited with fiber. Of course the amount of insulation board materials used by different companies is different. In terms of Hua Heng, siliceous insulating boards can be divided into insulating panels for casting slabs and insulation board for intermediate tank according to the usage. The latter one can be divided into liner plate (wallboard, side panels, baseboard) and impingement plate based on parts it is used on. Siliceous insulating panels use quartz sand as the main material and are composited with fiber. Method for manufacturing a silicon insulating panel is divided into semi-dry method and wet method. It is used for casting ingot insulation cap of the killed steel and continuous casting tundish.
- Q: Concrete composition and function of magnesia bond used in refractory
- According to the chemical composition and use can be divided into metallurgical magnesia, magnesia brick, magnesia brick, magnesia brick, magnesia calcium brick, magnesia brick and other varieties. Its performance is greatly affected by CaO/SiO2 ratio and impurities. High purity magnesia brick refractoriness under load and thermal shock resistance are better than the general magnesia brick. High refractoriness, has good resistance to alkaline slag and iron slag, is a kind of important senior refractories. Use of magnesia product production by sintering process, sintering temperature is 1500 ~ 1800 DEG C, in addition, you can also add chemical bond, made of brick and unshaped refractory material. Mainly used in open hearth furnace, electric furnace, converter, oxidation non-ferrous metal smelting furnace, cement kiln and alkaline refractory kiln etc..
- Q: I want to know what is the slim in the refractory bricks
- lining brick and refractory clay in the teeming ladle; high alumina brick, high alumina lining brick and high alumina refractory mortar can make cement kiln and glass melting furnace in the building materials industry for anti-slide. Taiyuan in Shanxi province is the famous place of origin; hard paste in the refractory clay is used as blast furnace refractory: // b, in agriculture as a fertilizer high alumina clay is also used in oil wells, which generally do not dip in water; accounting for 2/3 of abrasive products in the metallurgy, hard and semi-hard clay can be manufactured as ceramics for daily use. what you said should be slime. High-alumina clay can be resistant to high temperature after calcination! Refractoriness refractory clay refers that the refractoriness is more than 1580 ℃ with greater hardness and specific gravity and high refractoriness. except higher refractoriness, such as aluminum sulfate, the dosage accounts for about 70% of refractories; refractory clay and high alumina fused cast brick are widely distributed in China.
- Q: What is the role of the vermiculite fireproof material?
- It can be widely used in construction, decorative ceiling, wall, floor and fireproof door . Especially suitable for airport, railway station, passenger terminal, exhibition hall, hotels, shopping malls, hotels, and other public places and factory, fuel warehouses which have high requirements for fire proofing, etc. With its special thermal insulation, it can also be made to the various types of heat insulation board offered to machines (such as a variety of industrial furnace and assembly line equipment) and furniture, etc. Due to the low density of the product itself, a lot of shipyards in foreign countries use it as ceiling, wall and deck, so the development potential of the domestic shipbuilding market is huge.Expanded vermiculite is porous, lightweight, and dystectic, the most suitable for insulating materials at high temperature (below 1000℃) and fire insulation materials. In the experiment, 15cm- thick cement vermiculite burns for 4-5 hours under 1000℃, but the back temperature is only 40℃. 7 cm-thick vermiculite slate burns for 5mins through the fire flame welding net under 3000℃, the frontage melted, but you don’t feel hot with your hands holding the back side. According to aforementioned, vermiculite slate is superior than all insulating material, such as asbestos, and diatomite products.
- Q: Selection of refractory materials?
- Acid refractory with silicon oxide as the main component, are commonly used in brick and clay brick. Silica is silica containing more than 93% silica products, raw materials used in silica, silica and other waste, the acid resistance of slag erosion ability, high load softening temperature, volume shrinkage after repeated burning, or even a slight expansion; but it is vulnerable to the erosion of basic slag, low thermal shock resistance. The brick is mainly used for thermal equipment of glass furnace, coke oven, acid furnace etc.. Clay brick with refractory clay as the main raw material, containing 30% to 46% of alumina, weak acid refractory material, heat shock resistance, resistance to acid slag, widely used.
- Q: What are the requirements for the performance of refractory materials?
- Refractory materials should have very high refractoriness, high temperature heat load and resistance to softening, melting; with high volume stability, resistance to high temperature and heat load, volume shrinkage and only uniform expansion; high strength at room temperature and high temperature strength, high load softening temperature, under the joint action of heat load and heavy load, no loss of strength, creep collapse; Electric furnace analysis should have good resistance to thermal shock, resistance to rapid temperature changes, no crack, not flaking; with excellent slag resistance.
- Q: Why should graphitic refractory materials be used now that graphite can burn?
- Materials for refractory must have the following characteristics and properties: 1, high stability: Anti-oxidation, anti-reduction, thermal decomposition; 2, high melting point : 2800℃; 3, low price. Graphite has all three characteristics and properties, especially melting point and stability.
- Q: What is refractory cement?
- Ordinary portland cement is common cement with relatively high early strength, while refractory cement is low in this regard. Refractory cement is a characteristic cement which can only be used in special projects, not suitable for general engineering. And in the winter, it is not suitable for construction use.
- Q: How to make the service life of refractory materials longer?
- Take acid resistant refractory materials as example: the atmosphere should be acidic atmosphere, if used in an environment whose temperature is 1900℃, it would exacerbate the loss of refractory materials, so don’t use overloaded. Second, select the appropriate refractory materials according to the environment. For example, if its operating temperature is 1800℃, generally speaking, the normal use of it according to the instruction of refractory materials would be fine.
- Q: Who knows about the types of Dalian thermal insulating and refractory materials?
- There are many Dalian thermal insulation materials, which can be divided into organic and inorganic thermal insulation materials. Materials include inorganic thermal insulation materials, polyfoam, mineral wool products, foam glass, expanded perlite insulation products, gelatine powder EPS grain heat insulating slurry, sprayed mineral wool, thermal insulation product of foam cements, and vacuum thermal insulation board.
