Abstract
A two-dimensional axisymmetrical steady-state base thermal model is developed for electron beam (EB) melting and refining. A computer simulation is carried out, according to the proposed model, for various powers of EB heat source. Temperature distributions and heat flows in a cylindrical copper ingot, confined in a copper water-cooled crucible are calculated. The calculated and experimental observed shapes and/or depths of the metal pools are compared and a reasonable agreement is observed.
