FIELD: powder metallurgy, namely processes for semi-continuous pressing of consumable electrodes and die for making such electrodes.
SUBSTANCE: method comprises steps of pouring charge into cylinder-cone die by dozes and pressing each doze of charge with use of pressure plate having dents and indentations; preliminarily compacting charge particles in cylindrical inlet portion of die by main effort of pressure plate and shifting them along circumference direction. At final compaction of charge in cone part of die particles are shifted in addition along radius successively in several directions. On cylindrical inlet part of die helical profiled grooves are formed; said grooves have lead angle less than friction angle. On cone squeezing part there are annular portions with variable conicity degree successively turned one relative to other.
EFFECT: production of high-strength electrode.
