FIELD: pipes.
SUBSTANCE: invention relates to design of cold roll mills with moving roller body. Mill stand comprises stationary bed, connected with drive moving body with vertical working rolls installed in it, their rack drive with gears located on rolls, and racks, lower one being fitted in stationary bed, and upper one is fixed on swing crossbar mounted on an axis and equipped with hydraulic cylinder, and retainer in form of wedge connection with support and driven by hydraulic cylinder arranged at end of swing crossbar, perpendicular to rolling axis. Higher reliability and durability of stand by fixing crossbar from arbitrary displacement in horizontal plane during rolling is ensured by that crossbar is equipped with additional attachment axis. Attachment axes of crossbar are coaxial to each other and are located parallel to rolling axis.
EFFECT: fixing device is equipped with additional support arranged at opposite end of crossbar, wherein working surfaces of supports are covered with plates.
