摘要:

電子束冷床熔煉（EBCHM）技術是材料冶金領域的新興技術之一，在航空工業和國防科技中發揮著重要作用。簡述了EBCHM技術的原理，探討了EBCHM設備核心部件電子槍和冷床的發展歷程。介紹了國內外近年來EBCHM在多個材料領域的最新研究和實際生產現狀，重點追蹤了在難熔金屬鈦、釩，高溫合金鎳和太陽能級多晶硅等材料的熔煉和提純中如何控制EBCHM工藝以達到使原材料去除雜質、無偏析、成分均勻的目的。比較了國內外EBCHM技術的發展和設備熔煉能力現狀。最后結合國家發展需求對EBCHM技術的發展趨勢進行了展望，為今后在工業中能更好地應用EBCHM技術提供參考。

Abstract:

Electron beam cold hearth melting (EBCHM) is one of the newest technologies in the field of material metallurgy and plays an important role in aviation industry and national defense technology. In this paper, the principle of EBCHM technology is described, and the development of electron gun and cold hearth of EBCHM equipment are discussed. The latest research and production status applied in the fields of materials in recent years are reviewed, especially the methods to control EBCHM process in the smelting and refining of refractory metals such as titanium and vanadium, superalloy nickel and solar polycrystalline silicon in order to remove impurities, avoid segregation and homogenize composition are introduced. The research status and melting capacity in China are compared with that in other countries. Finally, the tendency combined with national demand of EBCHM is also prospected, so as to provide reference for further industrial application of EBCHM in the future.
