摘　　要：本文主要对氢等离子体电弧熔炼技术在难熔金属提纯方面的应用进行了综述。介绍了等离子体电弧炉的原理与结构,重点讨论氢等离子体电弧熔炼技术在难熔金属提纯方面的优势,最后阐述了H2在熔炼提纯中发挥的重要作用和机理。The refining effect of hydrogen plasma arc melting（HPAM） on refractory metals has been summarized. The structure and principle of a plasma arc melting furnace were introduced and the advantages of HPAM on refining of refractory metals were also discussed. At last H2 involved in the plasma arc melting are considered to play an important role in the melting process.
