It is shown that the technology of electron beam melting is the most challenging process for producing of quality extra-pure ingots of metals and alloys. The works on the development of these technologies were started at the E.O. Paton Electric Welding Institute in the 60s of the last century. To realize the technologies of electron beam melting in practice, the specialized electron beam installations of various designs were designed and manufactured at the E.O. Paton Electric Welding Institute. Mathematical models of the processes of refining, evaporation and solidification in electron beam melting were developed. The carried out research works showed that the technology of electron beam melting is the most effective and economically justified method of producing extra-pure niobium, tantalum, vanadium, zirconium, copper and many other metals. The technologies were developed for industrial application of this method for producing ingots of non-ferrous metals and their alloys. The works are carried out for the improvement of existing and development of new alloys for the needs of domestic industry, medicine and defense sector, as well as technology of their melting by the electron beam melting method.
