FIELD: processes for rolling improved-quality round steel shapes of mean and large diameters.
SUBSTANCE: method is designed for rolling with use of two-roll finishing stand, round steel shapes of mean and large diameters d>100 mm. Enhanced accuracy of geometry of rolled round shape and simplified adjustment of final roll grooved pass in two-roll horizontal stand is provided due mutual shifting of rolls at their adjustment in horizontal plane by angle in range 0 - 30° and due to using thrust cones in set of rolls in order to prevent directed axial displacement of rolls caused by metal deformation in roll grooved pass restricted by non-coaxial rolls.
EFFECT: enhanced accuracy of shape geometry, simplified adjustment of final roll grooved pass.
