Considering the material price, processing difficulty, service life and other factors, we believe that the nozzle made of Tungsten Cemented Carbide is the most durable and cost-effective nozzle, which can be said to be the best nozzle. So far, cemented carbide nozzle has become one of important cemented carbide products in China. Therefore, the Ministry of Industry and Information Technology (MIIT) of the People's Republic of China has also specially prepared the non-ferrous metal industry standard ICS77 Relevant standards of 160 CCSH72 YS YST TUNGSTEN CEMENTED CARBIDE THREADED NOZZLE.
Tungsten Cemented Carbide Nozzles (Reaming & straight hole nozzle)
Tungsten Cemented Carbide Nozzle is made of precision machinery and tungsten carbide powder and Co, Ni as metallic sintered material (superhard alloy). The bending resistance reaches 2300 N/MM and the hardness reaches more than HRA90 degrees. When machining tungsten cemented carbide nozzle, it is necessary to use precision grinding and surface treatment to achieve hole roughness of Ra0 The roughness at 1 and R at both ends is Ra0 025. A radius of curvature is designed at the two entrances to ensure the smooth passage of threads. Due to the overall material processing, there is no elevation angle on the drilling hole. Compared with the ruby nozzle, the phenomenon of easy bending and blockage has been improved. Cemented carbide nozzle is formed by hot pressing sintering of hot straight hole and hill hole. It has been widely used in abrasive blasting equipment and hard alloy nozzle due to its excellent wear resistance and long service time.
