The actual state concerning raw materials, energy, technology and ecology worldwide predetermines the development of new metallurgical technologies and equipment based on thermal plasma application as a concentrated heat source and for chemically active components of the processes. A classification of the existing plasma technologies and equipment is presented including the initial working raw materials, and the type of resulting materials. The main pilot plasma technologies and such with industrial application are indicated.
The most important factors predetermining plasma technology development in metallurgy are evaluated.
Most perspective tendencies for thermal plasma application in metallurgy are shown, based on actual results, experience, raw materials state, technological, economical and ecological conditions.
