Manufacturing good quality Silicon carbide
Product Description
Description:
Silicon carbide is made of silica sand, coke, wood and other raw materials by resistance furnace smelting at high temperature. It hassteady chemical composition, anti-abrasion, anti-corrosion, high temperature resistance, good heat conduction and so on. Now SiC produced by China's industry can be divided into black SiC and green SiC.
Use:
They are mainly used in four big application fields: functional ceramics,refractories, abrasives and metallurgical raw materials .
SiC is suitable for cupola and electric furnace.
As deoxidizer, it is widely used in foundry and steel industry. It can rapidly increase the temperature of molten steel, shorten smelting time, at the same time, it also can play deoxidizing, increasing carbon and silicon, heating up role. It can improve the quality of steel.
Characteristics:
1. Increasing carbon and silicon, reducing the consumption of
carburant,ferrosilicon and other alloy, saving the cost of per ton steel.
2. AS SiC is oxidized, it can release a large number of heat energy, reduce the cost of electric, lower the cost of production.

- Q: What kind of flexible fireproof material is really good?
- The best one is grade A fireproof material. A-class fire flexible material adopts clay, stone, sand, cement blocks and other inorganic powder and modifier and product density is 2327 kg/m3. Upon examination, the combustion performance of this product is in accordance with the grade A specified requirements and additional classification meets A s2, d0, t0 level requirements. According to GB 8624-2006, the combustion performance of product reach A2 - s2, d0, t0 level.
- Q: What refractories are resistant to fluorine gas?
- It is recommended to use fused-quartz brick, which will produce hydrofluoric acid fluorine (an acidic gas) when water vapors. It is cheap. While it is recommended to use silica?brick if it exceeds 1,200 degrees. So acidic refractory is an advisable refractory for using. It works well if the temperature is below 1200 degrees.
- Q: How to apply the alumina powder on refractories?
- The most common one in use is the refractory bricks.
- Q: Who can introduce the external wall thermal insulation materials fire rating regulations?
- According to public fire-fighting [2007] No. 182, the contents of the notification on the implementation of a number of issues of national standards GB8624-2006 "building materials and products combustion performance classification", since there is large differences between the new version of the standard GB8624-2006 and the old version of GB8624-1997 in the principle, hierarchical structure and test methods. According to the cintent of notification, in order to ensure a smooth transition between the old and new standards, the current national standard "Fireproof? Specification of Building Interior Decoration?Design" GB50222, "fire?safety?rules of tall civil buildings design" GB50045, "Fireproof? Specification of Building Design" GB50016 have not completed the relevant amendments, the new classification method of GB8624-1997 and GB8624-2006 can be used for temporary reference in terms of combustion performance of materials . From GB8624-2006 standard implementation, the classification of combustion performance is too granular, which do not match to the actual construction of the current project in our country. Therefore, the relevant departments carry on the 3rd amendment for the GB8624-2006 standards, namely GB8624-2012, and it will be released on December 31, 2012 and implemented on October 1, 2013. The combustion grading requirements in the standard: Level A is non-combustible materials (products); level B1 is nonflammable material (products); level B2 is combustible materials (products); level B3 is flammable materials (products).

- Q: what is the fireproofing material of engine room? who knows it ?
- machine room fireproofing materials include: Inorganic binder: The main material includes sodium silicate, gypsum, phosphates, cement,ect.; refractory mineral filler: aluminium oxide, asbestos powder, calcium carbonate, perlite, cornstarch, ect.; nonflammable organic resin: it mainly includes polyvinyl chloride, perchloro-ethylene, chlorinated rubber, neoprene latex, epoxy resin, phenol resin, ect.. nonflammable fireproof addictive: it mainly has phosphorus, halogens, nitrogen organic compounds (chlorinated paraffins, tributyl phosphate,deca-brominated diphenyl ether), and boron series (boric acid, zinc borate, aluminium borate), antimony system, aluminium series, zirconium system, etc. inorganic compounds.
- Q: Refractories for iron-making blast furnace?
- Cement kilns?
- Q: Detailed description of magnesia dolomite refractory material?
- In the cement kiln firing zone, the f-CaO in the dolomite material is easily combined with the C2S in the clinker to form C3S, so the kiln cover can be easily hung, and the kiln crust and the refractory brick are firmly combined and easy to maintain.
- 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: Who knows about the types of Dalian thermal insulating and refractory materials?
- There are mainly following types: rock wool series, rubber and plastic series, glass wool series, mesh series, ventilation series, mortar series, extruded sheet series, geothermal series, insulation supporting pin series, glass silk cloth series. I hope my answer can help you.
