Powder metallurgy has core process advantages such as high material utilization, low unit energy consumption, and environmental protection. It is a technology that is in line with the future direction of carbon neutrality.   In recent years, with the maturity of powder metallurgy technology and the trend of miniaturization of parts, two emerging process routes, metal injection molding (MIM) and 3D printing (AM), have rapidly emerged.   At the same time, the supply of high-quality powder raw materials has begun to become a major factor restricting the development of the industry.   Small and complex parts are undoubtedly more suitable for injection molding and 3D printing (particle size of 20μm or even smaller), and have been increasingly used in high-end fields such as aerospace, medical, electronics, and military industry.   Therefore, the preparation of metal powders with high purity, good sphericity, small particle size and narrow distribution, and low oxygen cont...

  1. MgO-ZrO2 Ceramic Metering Nozzles (lnserts) They are mainly used in steel making continuous casting ladles, converter tundishes, and converter taphole slag retaining mechanisms. Features: Good erosion resistance, corrosion resistance Thermal shock stability The service time is generally 50 hours, which solves problems such as clogging, cracking and diameter expansion. Related general products: Continuous casting tundish upper nozzle Tundish quick change nozzle Fixed diameter nozzle for continuous casting. 2. MgO-ZrO2 Ceramic Atomizing Nozzles They are mainly used in the powder metallurgy industry, the smelting of ferrous and non-ferrous metal powders, such as nickel-based alloy powders, copper powders, stainless steel powders, iron powders and other super alloy powders. Features: Higher density, Excellent resistance to high temperature corrosion, Resistance to erosion by metallic liquids Thermal shock performance.

  In powder metallurgy (PM) processes, boron nitride and zirconia ceramic nozzles are used depending on the type of metal materials.     Main Features of Ceramic Nozzles   High-temperature resistance: withstands temperatures above 1500  ° C from molten metals or plasma flames.   Wear resistance: resists erosion from powder or gas flow for long-term operation.   Chemical inertness: does not react with active metals or gases.     Applications at Different Stages of Powder Metallurgy Stage Process Functions of Nozzles Ceramic Nozzles Typical Metals Powder Preparation Gas Atomization High-pressure inert gas (such as nitrogen or argon) impinges on the molten metal stream to form fine powder; ceramic nozzles control flow and particle size. Boron Nitride and Zirconia High-purity or reactive metals such as titanium and nickel-based alloys. Water Atomization Ceramic nozzles provide corrosion resistance and precise flow control. Zirconia Used in high-...
