Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

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.
