摘要

FIELD: process engineering.;SUBSTANCE: invention relates to metallurgy and can be used at pipe rolling unit 8-16'' with Pilger mills JSC CPRP. Pilger mill roll comprises working section and idle section of 220 and 140 degrees at 1150 mm diameter barrel. Working part comprises round-cross-section pass with tangential crosswise taper grooves. Pass length consists of the hammer in length of 0.36-0.37 of the total length of working section with angle of crosswise taper groove varying over the hammer length from 32-37 to 20-25 degrees in cross-section of transition to polishing section. Polishing section features the length of 45-0.46 of the entire length of working section. Besides, it features the angle of lengthwise taper groove making 0.19-0.20 of the working section total length. Roll hammer with central angle of 80 degrees, total reduction of sleeves and hollow ingots over diameter from 70 to 80 mm, comprises the pass with crosswise taper grooves decreasing from 35 to 22 degrees. It is divided into three sections with central angles α₁=20, α₂=25, and α₃=35 degrees, with smooth distribution of reduction over diameter.;EFFECT: decreased rejects, lower metal input factor.;5 cl, 1 tbl
