FIELD: metallurgy. ^ SUBSTANCE: invention relates to pipe rolling, particularly it relates to mills for pipes cold rolling. Mill of cold rolling of pipes contains working mill, stand of which is connected to guide mechanism of rod fixation, including rod's chuck, feed gear with screws and drive, blank chuck with nuts. Nuts interact to screws of feed gear and blank's chuck is moved in the direction of deformation site. Feed gear is located between working mill and blank's chuck and is fixed on stand of mill. For holding of screws there are front and back support holders, rigidly connected by rods in pairs. ^ EFFECT: there is provided improvement of rolled pipes ensured by stabilisation of rolling process, increasing of reliability and durability of mill ensured by increasing of rigidity and reduction of mill length. ^ 2 dwg
