FIELD: process engineering.
SUBSTANCE: proposed method comprises electroslag remelting of ingots from 04X14T5P2"Ф-Ш"-grade low-ductile steel with boron content of 2.0-3.0% and bottom and shrinkage parts from ductile carbon steels, turning said ingots to produce billets wherein through central bore is drilled, and heating them to 1040-1060°C. First, said ingots are pierced at helical rolling stand. Then, they are rolled at Pilger stand to tube sections to cut off process wastes so that ductile carbon tube 500-600-mm-long ends are made on dummy ingot and Pilger head side. Then, they are straightened and cut into multiple length tube stock and ends. Now, they are bored and turned to cylindrical tubes to be shaped to hexagonal tube billets. Note here that billet sizes and machining conditions are specified for all machining steps.
EFFECT: decreased wastes and ruled out rejects.
