摘要
采用真空熔炼、氮气保护及气雾化法研制生产了纯Ni粉,粉粒的球形度高,流动性好,长条状及不规则形粉粒少,化学成分纯净,有害杂质含量少,非常适用于药芯焊丝的生产.
The paper introduces the key producdon procedures for pure nickel powder: vacuum melting, nitrogen shielding, and fog- solidification. The powder has many advantages: high content of globular grains, pure composition etc. Thereby, the nickel powder is suitable to produce flux - cored welding wires.
