Breif description
Silicon carbide ceramic nozzle / flame tube for kiln furniture is recommended for most kilns and furnaces working below 1380℃, however XR can also offer NSiC and RSiC nozzle tubes for applications working at higher temperatures.
Silicon carbide ceramic nozzle are widely used in high temperature ceramic kiln,steel quench furnace,large boiler,power plant desulfurization dusting equipment and high-tech military equipment. The industry involves but not limited to daily-use ceramics, sanitary ceramics,porcelain insulator,crystallite glass, metallurgy, magnetic materials, electric power, chemical industry, steel, petroleum, machinery, military industry,etc.
