FIELD: process engineering.
SUBSTANCE: proposed method comprises electroslag remelting of 470±5 "хвн." 270±5×3050±50 mm ingots from 04X14T5P2"Ф-Ш"-grade low-ductile steels with boron content of 2.0 to 3.0% with bottom and shrinkage parts and specified height to make Pilger heads in tube stock rolling and seed ends from ductile carbon steels, turning and boring to make hollow ingots to be rolled to tube stock. It comprises also removing machining wastes, that is, Pilger heads and seed ends to make tube sections of ductile carbon steels. Then, tube sections are cut to tube stock to be bored and turned to tube billets. Holes are bored for pull chain for hot shaping at ductile carbon steel parts. Note here that billet sizes and machining conditions are specified fat all machining steps.
EFFECT: reduced wastes and rejects.
