The question of efficiency of use of metalized pellets for production of consumable electrodes subjected to electroslag remelting process in order to obtain metal pure in phosphorus and impurities of non-ferrous metals is considered. Analytical estimation of the processes occurring during the interaction "pellet - ligature" has been made, which allowed to obtain optimal parameters for the formation of consumable electrode from ligature and metallized pellets. The experimental estimation of temperature interval of pellets preheating 300...500 °C was carried out. The optimum temperature of pellets preheating is determined, which is 400 °C. The obtained prototypes are investigated and it is established that pellet preheating up to 400 °C allows to obtain fusion of pellet surface layers with ligature. The technology of formation of expendable electrodes from metalized pellets by pouring liquid ligature into a special liner with a polystyrene rod pre-installed in it has been developed.
