FIELD: technological process.
SUBSTANCE: forging is obtained by forging an ingot by hydraulic forge press in four-die forging device. The forging undergoes thermal processing and shot-blasting in shot-blast cleaning chamber. Further ultrasound control of forging is performed along the whole forging length, determining actual borders between flaw-free part and sinkhead and bottom. Then sinkhead and bottom of the forging are removed at the determined borders.
EFFECT: enhanced metal yield.
