Description:
Silicon Carbide is produced by melting a mixture of silica sand and cokes in ultra high power electric furnaces. Silicon Carbide is chemically stable and has high corrosion resistance, which makes it hard to corrode from exposure to alkali or acid. Silicon carbide is also characterized by its high hardness, outstanding heat resistance, low thermal expansion, resistance to chemical reaction, and ability to function as a semiconductor.
Application:
SiC is suitable for cupola and electric furnace, widely used in iron foundries and in steel mills as deoxidizing agent, especially in ladle furnaces and electric arc furnaces during slag treatment. Silicon carbide can improve the temperature of molten steel rapidly, shorten the melting time, play the role of deoxidizing, increasing carbon and silicon, heating to improve the quality of steel.
Feature:
Black SiC, dissolved in a basic oxygen furnace used for making steel, acts as a fuel.
1.Additional energy liberated allows the furnace to process more scrap with the same charge of hot metal.
2.Silicon Carbide can also be used to raise temperatures and adjust the carbon and silicon content.
3.Silicon carbide / SiC can reduce the cost of production, produce cleaner steel and lower emissions.
Chemical Composition
- Q:what's the classification of fireproof and thermal inuslation matertial?
- Inorganic thermal insulation material can do it, such as glass wool,rock wool,foam glass,etc. phenolic foam materials in organic foam material is special. phenolic foam not only has good thermal insulation properties but also can be composited with steel plate and other materials, A class thermal insulation materials that reach A class combustion performance include: rock (mine) wool, foam glass, EVB, etc. thermal insulation materials with A class combustion performance mainly include: phenolic aldehyde,gelatine powder polyphenyl granule, etc. thermal insulation material of fire barrier zone can use rock (mine) wool, foam glass, EVB and other materials with A class combustion performance.
- Q:Who knows about the criteria of fireproof and thermal insulation materials?
- The standards of fireproof and thermal insulation material. 1. the height of buildings is greater than or equal to 100 m, the combustion performance of thermal insulation materials should be A-level; 2. the height of buildings is greater than or equal 60 m but less than 100 m, the combustion performance of thermal insulation materials should be no less than B2-level. When using B2-level thermal insulation materials, fire barrier zone should be set in each floor; 3. the height of buildings is greater than or equal to 24 m but less than 60 m, the combustion performance of thermal insulation materials should be no less than B2-level. When using B2-level thermal insulation materials, fire barrier zone should be set in every two floors; 4, the height of buildings is less than 24 m, the combustion performance of thermal insulation materials should be no less than B2-level. When using B2-level thermal insulation materials, fire barrier zone should be set in every three floors.
- Q:Kinds of refractory mortar
- It needs no heating when hardened. There are two kinds of refractory mortar, the finished products and semi-finished products. Clinker is compounded in proportion according to the hardening temperature. (3) Chemical bonding refractory mortar is made from refractory aggregate and chemical binders (inorganic, high alumina refractory mortar). After this refractory mortar with thermal hardness is hardened, it has some contraction. Ther is a wide variety of refractories used on the constrcuction sites: // a, Advanced refractories (1770 ~ 2000 ℃) and AAA level refractories (2000 ℃ above). It can only be delivered in dry state. Air hardening refractory mortar is often compounded air hardening binders such as sodium silicate. It will harden below ceramic bonding temperature. According to different binding agents.
- Q:How to hang the suspended brick in the refractory masonry?
- First you can weld the metal fastener of the suspended brick and then hang up the brick.
- Q:Which refractory is suitable for the tunnel kiln?
- Shuttle kiln refractories requires the good thermal shock properties. Because the tunnel kiln is continuous firing furnace, the temperature in the kiln is long time stable and with little fluctuation. The shuttle kiln is intermittent kiln firing. The temperature in the firing kiln is adjusted by the firing curve. It is with a relatively short time and serious fluctuation. The seal and kiln car take use of the heavy corundum brick. If it is continuous kiln, the alumina hollow ball bricks are used in the burning zone. The seal of the burning zone takes use of the kiln car brick and the seal takes use of the heavy corundum brick.
- Q:What's the refractory material?
- Frequently used refractory material: AZS brick, corundum brick, direct-bonded?magnesia-chrome?bricks, carborundum brick, silicon nitride bonded silicon carbide brick, nonoxide refractories like nitride, silicide, sulfide, boride and carbide, and oxide refractories like calcium oxide, chromium hemitrioxide, alumina, magnesium oxide and beryllia. In general, the refractory material include the above. For more information, you can ask for specific advice.
- Q:Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?
- If the outer packing is made of solid wood, it must be fumigated! If it is not solid wood, you can do without!
- Q:What is the material composition of the new fire-resistant coating?
- New fire-resistant coating generally consists of base material, dispersion media, flame retardants, fillers, additives (plasticizers, stabilizers, waterproofing agents, moisture, etc.). (1) Base material is the basis of the composition of the coating, and it is the main film-forming substance, playing a decisive role in coating performance . For fire-resistant coating, its base material must be capable of matching with the flame retardant to constitute an organic fireproofing system. The base material commonly employed at home and abroad includes inorganic and organic film-forming material. Inorganic film-forming materials include silicate. Si03, K2 Si03Na2 Si03), silica and phosphate [Al. (HPO.). ] ect. There are a wide range of organic film-forming substance, usually flame retardent organic synthetic resins, such as phenolic resins, halogenated alkyd resins, polyester, halogenated olefin resins (such as vinyl chloride resin), amino resin (melamine resin, urea resin, etc. ), tar-based resins, furan resins, heterocyclic resins (e.g., polyamide-imide, polyimide, etc.), organic elements resins (e.g. silicone resin), rubber (halogenated rubber such as chlorinated natural rubber) and so on. There are numerous latex taking water as solvent. www.hc3600.
- Q:Why should graphitic refractory materials be used now that graphite can burn?
- In theory, any substance can burn as long as certain temperature is reached. Graphite is turned from diamond under anaerobic condition and at high temperature of 2 000 ~ 3 000 ℃. that is to say, ignition point of graphite (lamellar graphite ) under anaerobic condition will be at least above 3 000 ℃. There are many types of graphite, and their ignition points are also different. Ignition point of pyrolytic graphite is much low. Except for a few cutting-edge areas, fire endurance demand for most areas in daily life (eg. brake pad will add a certain amount of graphite) is under 1000 ℃. Therefore, graphite can be used as refractory material. That is, graphite can both burn and can be used as refractory material, which are not contradictory.
- Q:The manufacturing technique of refractory material
- Melt blowing method is to melt the ingredients first, In addition, hiphotos, organic impurities, to be mixed, add sulfite pulp waste liquid into magnesia billet , ensure the accuracy of the product dimension. The products are mainly used for light refractory. then dry and fire with sintering to reduce the firing shrinkage of products, making it disperse into fiber or hollow sphere. The porpose of pre sintering raw material is to Sintering method is pre-sintering part of the raw material into clinker. such as adding binding clay into aluminum silicate blank
