Abstract
During electron beam zone melting , the stability of melt zone is essential for the material purification and the growth of single crystal .The stability of melt zone is actually a manifestation of the stability of high voltage pow-er system in the electron beam zone melting furnace , and several factors lead to the instability of electrical parame-ters of high-voltage power system .Aiming at the instability phenomenon of high-voltage power system during elec-tron beam zone melting Mo alloys , this paper analyzes the causes of the instability , including anode materials , re-sidual vacuum , coating generating during melting , as well as the equivalent internal resistance and control circuit response time of high-voltage power system , and proposes responding solutions .It's indicated that synthetically con-sidering above factors and taking appropriate measures , instability problem can be effectively addressed .关键词
