silicon carbide protective tube
Description of Silicon Carbide Protective Tube
Silicon carbide tube have superior characteristics, such as corrosion Resistance, high temperature tolerance, oxidation
resistance, no dropping slags, superior thermal Conductivity, high bending strength, non-deformation for a long time serv
ice, etc .
The series of beams are ideal kiln furnitures for sanitary ceramics, household porcelain, building ceramics, electric porcelain, refractories, etc. They are specially used for load-bearing beams in shuttle kilns, tunnel kilns, roller hearth kilns and othe
r industrial kilns.

Application of Silicon Carbide Protetive Tube
1-- Abrasive
Due to its super hard, can be prepared into various grinding with grinding wheel and sand Cloth, sand paper and various abrasive, which are widely used in mechanical processing industry. industrial silicon carbide in our country is mainly used as abrasive, made of black silicon carbide Grinding tool, used for cutting and grinding low tensile strength of material, such as glass, ceramics, stone and refractory, etc., also used in cast iron parts grinding and non-ferrous metal materials.
2-- Refractory
(1)Advanced refractory black silicon carbide.Mainly used to make advanced silicon carbide products, such as silicon carbide products, and gas turbine components, nozzle. The combination of silicon carbide silicon parts, high blast furnace lining materials, high temperature furnace components, high temperature kiln kiln supporting members, refractory sagger, etc.
(2) the secondary refractory black silicon carbide, silicon carbide is more than 90%.The main used in the manufacture of medium high temperature resistance furnace components, such as the muffle furnace lining material, etc. These artifacts in addition to the use of silicon carbide heat resistance, thermal conductivity, in many fields, the chemical stability of combination it.
(3) low grade refractory black silicon carbide. This is greater than the content requirements 83%, mainly used in iron bath, hot metal ladle, zinc smelting and sponge iron makingIndustry such as the lining.
3--Military
(1) Center density of silicon carbide, and 20% lighter than the Al2O3, hardness and elastic modulus. Volume is high
prices are much lower than those of boron carbide, can also be used for armored vehicles. And aircraft belly and bulletproof extra clothes, etc.
(2) Point application in some special places, such as used to make high power laser. Light mirror its performance is better than that of copper, due to the low density, good rigidity, little deformation.CVD and lightweight mirror reaction sintered silicon carbide has. The extensive use in the space technology.
4-- Electron and Electricians Field
Silicon carbide heating element is a commonly used heating element, because it has
Simple and convenient operation, long service life, the advantages of wide use,
Become hot material in one of the most durable and cheap and fine, make
With the temperature to 1600 ℃.
5-- Wear Resistant and High Temperature Field
Using silicon carbide ceramics high hardness, wear resistance, resistance to acid and alkali corrosion, such as performance, in the machinery industry,
In chemical industry is used for the preparation of a new generation of mechanical seal materials, such as the sliding bearing, corrosion resistance
Pipe, valve plates, and fan blades.
(1) Packing: standard export packing , wooden case , cartoon case, It will be protect the products well.
