FIELD: pipe rolling, applicable on pipe- rolling plants with Pilger rolling mills. SUBSTANCE: bimetal ingot is fed to the mill against the stroke of fusion of its central part. At the outlet of the broaching mill the working and sink rolls are reduced to value providing for condition (hp+hn)/2 ≤ Dc, where hp-distance between working rolls at outlet, mm; hn-distance between sink rolls at outlet, mm; Dc-source ingot diameter, mm. EFFECT: prevented sliding of one metal layer relative to the other at ingot broaching.
