The silicon carbide nozzle is made of silicon carbide material, which is obtained by heating sand and proper carbon in an electric furnace. The nozzle of this material is excellent in high strength, high hardness, strong corrosion resistance, drastic wear, high temperature resistance and the like function, in the harsh conditions have a long service life. Therefore, its application is also commonly used in ceramics, chemical, glass, metallurgy and other fields using natural gas, liquefied petroleum gas, gas, diesel and other industrial furnace nozzle, can effectively control the temperature balance within the kiln.
