FIELD: metallurgy.
SUBSTANCE: hollow ESR 660 mm OD 310-420 mm ID billets are turned and bored to hollow ingots-billets that feature 640 mm OD and 330-440 mm ID. Said ingots-billets are heated in continuous furnace to 1200-1220°C and rolled at PRU 8-16" with Pilger mills to 465×25-75 mm pipes with rolling-out µ from 2.36 to 4.43. Said hollow ESR ingots are cast to get diameter-to-wall depth ratio D/S=3.6-7.0.
EFFECT: improved characteristics.
