Abstract RU 2564198 C2

FIELD: metallurgy.

SUBSTANCE: method involves simultaneous cleaning of inner and outer surfaces of tubes from process lubricant immediately during rolling. For cleaning of the inner surface there used is a sleeve with annular blades of a truncated triangular profile on the outer surface, and removal of process lubricant from the outer surface is performed by means of a device made in the form of end washers, a flat cuff located between them and a support ring with central holes, which are assembled between two metal rings and installed directly on the outlet side of a cold pipe rolling mill on the rolling axis, the sleeve is made from elastic polymer material, end washers and the support ring are made from stiff polymer material, and the flat cuff is made from oil-resistant rubber.

EFFECT: reduction of complexity and labour intensity of a process.
