Abstract

1. Method for the production of high-quality pipes from 08Kh18N10T-Sh grade corrosion-resistant steel for nuclear power facilities, including casting ingots by electroslag remelting, drilling a central hole with a diameter of 100 ± 5.0 mm, heating the ingots to a duct temperature, piercing the ingots in an oblique rolling mill into sleeves, rolling conversion tubes on a pilgrim mill, cutting off technological waste - pilgrim heads and seed ends with a hot cutting saw, straightening pipes, heat treatment - austenization, mechanical eskuyu processing - refacing and the bore size of the finished with roughness outer and inner surfaces no more Ra 10,0 mm, characterized in that the rolling of mother tubes to produce a pilger process roll mills on HPT. ! 2. The method according to claim 1, characterized in that the hot rolled steel pipes are machined - bored and turned, on machines with a tracking system, into billet pipes with metal removal, the value of which is determined from the expressions! ΔSv.p. = КΔSв.c.,! ΔSn.p. = K1ΔSn.c.,! where ΔSv.p. - the value of the removed metal layer when boring by the proposed technology, mm; ! ΔSв.c. - the value of the removed metal layer during boring according to the existing technology, mm; ! K = (0.5-0.6) is the coefficient of reduction in the size of the removed metal layer during boring, large values of which relate to pipes of large diameters; ! ΔSn.p. - the value of the removed metal layer during turning by the proposed technology, mm; ! ΔSн.c. - the value of the removed metal layer during turning according to the existing technology, mm; ! K1 = (0.4-0.5) - coefficient of reduction in the magnitude of the removed metal layer during turning,
