Tungsten carbide nozzle is processed by precision machinery and tungsten carbide material (super hard alloy). The bending resistance reaches 2300N/mm, and the hardness reaches HRA90 degrees. When processing tungsten carbide nozzles, we do precision grinding and surface treatment to achieve a hole roughness of Ra0.1 and a roughness of Ra0.025 at both ends. There is a scientific curvature radius design at the two entrances. This design can ensure the smooth passage of the thread. Due to the overall material processing, there is no elevation angle on the drill hole. Compared with the ruby nozzle, the phenomenon of easy bending and clogging has been improved.
Mature applications of tungsten carbide materials:
Tungsten carbide nozzles are made by hot pressing and sintering of hot straight holes and dome holes. Due to its hardness, low density and excellent wear and corrosion resistance, tungsten carbide nozzles have been widely used in sandblasting and shot blasting equipment to ensure that the product can be used for a long time in the best air and abrasives. The advantages of tungsten carbide nozzles: corrosion resistance, long service life, excellent performance, high cost performance, and not easy to wear.
Tungsten carbide nozzles and other nozzles: commonly used nozzle materials include cast iron, ceramics, tungsten carbide, silicon carbide, and boron carbide. Ceramic nozzles are only used in non-aggressive lightweight equipment and abrasives in explosive cabinets. Tungsten, silicon, and boron carbide are the most popular mass blasting applications due to their long service life. Listed below is the comparison of the service life of tungsten carbide nozzles and other nozzles.
