| Abstract Scope |
Since the Electron Beam Melting (EBM) refining process, used for the smelting of rare metals, proceeds the removal of impurities in high temperature metals, to have an efficient ingot production through this process, the correlation of the specific removal of impurities in rare metals, according to electron beam energy density calculation through calculating the output of the electron beam with a numerical analysis approach, should be analyzed. In addition, it is necessary to optimize electron beam parameters for high purity of rare metals. In this study, the beam trajectory and energy were calculated by controlling the beam output of the electron beam gun through finite element analysis, and through this, the temperature distribution of the material was confirmed. In addition, to have calculated partial pressure of impurities that is use of the Vapor Liquid Equilibrium (VLE) in the Computer Coupling of Phase Diagrams and Thermochemistry (CALPHAD). |
