FIELD: metallurgy.
SUBSTANCE: invention relates to the method of producing seamless machined pipes with 530×13-18 mm size from steel of "08Х18Н10-Ш" grade. The method includes casting hollow ingots by electroslag remelting size of 670×in.280×1750±50 mm, boring and turning them into hollow cakes with 650×in.300×1750±50 mm, heating ingot-blanks in the process furnace to a temperature of 1250-1260°C, the issuance of ingot-blanks from the furnace, lubrication from two ends of ingot-blanks with a mixture of graphite and common salt in a ratio of 50/50 mass equal to 1000-1250 g, piercing-rolling of ingot-blanks in the mill of cross-screw rolling into sleeves of size 680×in.515×2800-2970 mm, rolling bushing on PPP 8-16" with pilgrim mills in disposal pipe size of 550×35×5700-6100 mm, line of technological waste seed ends and pilgrim heads saw hot cutting, editing the correct six-high machine, austenization, machining-boring and refacing metal recycling hot-rolled pipes measuring 550×35×5700-6100 mm in pipe size 530×13-18×5700-6100 mm.
EFFECT: reduction of a metal consumption coefficient.
