SGJ Exclusive Industrial Ceramic Silicon Carbide SiSiC/RbSiC/SiC
Carborundum desulfuraton nozzle the service life is 10-20 times of normal nozzle, 4-7 times of aluminum oxide ceramic nozzle,
can be usedin bad condition enviroment. Carborundum desulfuration nozzle is key parts of desulfuration euipments in fire power station, steel plant and big boiler etc.
SiC, Silicon Carbide Ceramic
SGJ Reaction Bonded Silicon Carbide Burner Nozzle are used for tunnel kiln, shuttle kiln, roller hearth kiln as the flame tubes. The SiSiC ceramic burner nozzles are also used for heating on either direct or indirect furnace systems.They can be also applied in industrial kilns of gas, oil etc, silicon carbide ceramic are widely used and adopted by domestic and overseas kiln companies.Reaction bonded silicon carbide burner nozzle can obviously control and adjust temperature balance inside the kiln with large width. SiSiC Burner Nozzles have been installed in most of the famous imported and domestic made kilns. Silicon carbide is one material of very high strength and usually made into Reaction bonded silicon carbide ceramic posts / SiSiC pillars for energy saving . The Reaction bonded silicon carbide ceramic posts / SiSiC pillars for energy saving are lightweight and keep straight after long time working. Its maximum working temperature is up to 1380ºC or 2500ºF. It is mainly in sealing applications (sealing rings and bearings), high temperature applications (burners) and as abrasion-resistant materials (sandblasting nozzles). The whole production process of silicon carbide material, starting with mixing through processing and ending with final inspection of the final products is situated in our company.
Advantages of RbSiC / SiSiC / refractory reaction bonded silicon carbide SiC burner nozzle tube
RbSiC / SiSiC / refractory reaction bonded silicon carbide SiC burner nozzle tube to match your existing kiln burners. We nowadays use Silicon carbide burner tubing as flame tubes for roller hearth kiln- sometimes also called RBSiC tubes for most applications. It has the following advantages:
1. High thermal shock resistance
2. Low thermal expansion and high conductivity
3. Stable dimension with no deformation or creep
4. Suitable for most kilns- shuttle, tunnel and roller hearth kiln
5. Long service life due to high quality material and reaction bonded production process
