Abstract: High speed and high reliability vacuum pumping system is needed for the electron beam melting furnace. This paper described the technical specification, the design ideas and methods, and structure configuration. A detailed calculation of the vacuum pumping system was carried out, which may provide a useful reference to develop similar vacuum equipment.

Key words: electron beam melting, vacuum system, outgassing amount, effective pumping speed, pump-down time
