The common elements of all the special electrometallurgy processes (vacuum arc, electroslag, electron beam, plasma-arc remelting) include a consumable billet, liquid film at its end face, drops with which the metal is transferred into the pool, the liquid pool and forming ingot. In the paper an attempt is made to generalize and clarify the earlier obtained data, on refining at each of the stages of liquid metal existence (film, drop, pool). Results of calculation of the degree of refining for different melting rates, drop size, and electrode geometry, and analytical assessment of the influence of each of the stages on refining effectiveness are given. Ref. 7, Tabl. 2, Fig. 3.
