Description

Technical Field

[0001] The utility model relates to the technical field of ceramic nozzles, in particular to a high-precision zirconia ceramic nozzle. Background Art

[0002] Industrial ceramics are one of the most widely used ceramics in engineering. With the continuous development of jet processing technology and material science, the materials used to manufacture nozzles have also changed greatly. Due to the rich resources, high hardness, excellent wear resistance and heat resistance of ceramic materials, they have been widely used in engineering.

[0003] The life and processing efficiency of zirconia ceramic nozzles are greatly improved compared with metal and carbide nozzles. The main failure mode of the nozzle is erosion and wear. The erosion and wear of the nozzle by the material particles during the jetting process is relatively serious, which shortens the life of the nozzle. In order to ensure the efficiency of the material jetting process, the nozzle needs to be replaced frequently. However, frequent disassembly and reinstallation to adjust the nozzle position will affect the efficiency of the jetting process. For this reason, a high-precision zirconia ceramic nozzle is proposed. Utility Model Content
