翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Electron beam furnace ： ウィキペディア英語版 Electron beam furnace An electron beam furnace (EB furnace) is a type of vacuum furnace employing high-energy electron beam in vacuum as the means for delivery of heat to the material being melted. It is one of the electron beam technologies. Electron beam furnaces are used for production and refining of high-purity metals (especially titanium, vanadium, tantalum, niobium, hafnium, etc.) and some exotic alloys.〔()〕 The EB furnaces use a hot cathode for production of electrons and high voltage for accelerating them towards the target to be melted. An alternative for an electron beam furnace can be an electric arc furnace in vacuum. Somewhat similar technologies are electron beam melting and electron beam welding. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Electron beam furnace」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
