Tungsten cemented carbide high-pressure water jet cutting nozzle, also known as cemented carbide water jet sand pipe, cemented carbide water jet sand pipe, tungsten steel water jet nozzle.
Abrasive nozzle, water nozzle, water knife, water knife sand pipe, high pressure water knife sand pipe. It is mainly used for metal cutting, ceramic cutting, stone cutting, glass and other materials cutting. Long service life, high hardness and good wear resistance.
Water knife sand pipe refers to the nozzle used for mixing abrasive and water at the jet outlet of high-pressure abrasive water jet machining machine tool. Because the internal jet condition is bad and the abrasive is accelerated, the wear inside the sand pipe is very large, so it needs to be made of very wear-resistant materials. Due to the scouring of high-speed abrasive particles, the sand pipe needs to have the advantages of high hardness and high wear resistance. At present, the better water knife sand pipes are basically made of cemented carbide. In cemented carbide, WC, as the main wear-resistant phase, exists in the form of particles, while CO is only used as adhesive. The existence of Co metal adhesive obviously has a great impact on its wear resistance. At present, YG6 is the most widely used brand in China.
The service life of cemented carbide high-pressure water jet cutting nozzle not only depends on the shape, size, type, process conditions, inner pipe finish and the wear resistance of the material itself, but also has a great influence. At the same time, it is closely related to the pressure of water knife equipment, whether to use abrasive, abrasive material and hardness.
