FIELD: plastic working of metals, namely ingot forging in presses of four-striker forging systems.
SUBSTANCE: method comprises steps of squeezing ingot by means of four strikers for forming four dents on lateral surface of ingot; squeezing said dents, feeding and tilting blank, sizing forged piece. Said dents are squeezed for forming octahedral cross section blank having width values of faces formed at squeezing process no less than width values of non-squeezed faces. Blank is subjected to tilting after each pass alternatively by angle 45° and 135° in the same circumference direction. Before sizing, blank is tilted by angle multiple to angle 22.5°.
EFFECT: less loss of yield for forged pieces after their mechanical working.
