2.Property of RBSiC Refractory silicon carbide burner nozzle / burner tube and pipe:
◊ Superior wear resistance, impact resistance and corrosion resistance
◊ Excellent flatness and temperature resistance up to 1380℃
◊ Excellent oxidation resistance
◊ Good dimensional control of complex shapes
◊ Easy installation
◊ Longer service life ( about 5 times more than that of alumina ceramic and 6 times more than that of polyurethane)
The reaction bonded silicion carbide ceramic ( RBSIC) is an ideal wear resistant material, which is especially suitable for the strong abrasive, coarse particles, classification, concentration, dehydration and other operations. Due to the above properties, SiSiC silicon carbide sic fog nozzle can effectively protect the part from high wear so as to prolong the service life of the equipment.
