FIELD: technological processes.
SUBSTANCE: invention relates to pipes rolling. Rolling mill stand has two forming rolls with intersecting axes and two transverse guides for rolled part (5) located on the side of rolling axis (R), made in the form of two fixed guide lines (6, 7) for the first rolling operations or in the form of guide disks rotating around vertical axis (50, 51) for the second rolling operations. Possibility of rolling at different stages of the mill stand operation with the help of fixed guide lines and rotating guide disks is ensured by the fact that the mill stand contains two turning devices that can be rotated using electric motors (40, 40') and can be locked in a fixed position, in which the transverse guides and transverse rotating guide discs (50, 51) interlock with the possibility of changing depending on the requirements for work. Fixed transverse guides have a circuit of forced circulation of liquid for cooling.
EFFECT: proposed transverse rolling mill stand for seamless pipes is equipped with a replaceable transverse guide device.
