FIELD: rolled stock production, possibly in sheet rolling, bar rolling and tube rolling mills.

SUBSTANCE: rolling stand includes foundation, lower and upper rolling rolls. Chocks of lower rolling roll with radial and thrust bearing assemblies are mounted on foundation. Chocks of upper rolling roll with radial and thrust bearing assemblies are mounted on chocks of lower rolling roll. Upper traverse bar is fixed to chocks of upper roll. Tightening bolts with nuts and embedded dowels are used for joining upper traverse bar with foundation. Radial motion mechanism of upper roll is arranged in chocks of upper roll. Axial motion mechanism of lower roll is arranged in chocks of lower roll. Axis of radial bearing assembly in each chock is turned relative to axis of abutted rolling roll by angle determined according to calculation formula.

EFFECT: lowered metal consumption of rolling mill, reduced labor consumption for manufacturing and mounting rolling mill, increased useful time period of bearing assemblies of rolling rolls, decreased expenses for rolling mill operation.
