FIELD: metallurgy.
SUBSTANCE: rolling gauge contains top and bottom rollers, each of them has backup rolls with fixed on it side washers and flexible inserts. Top roller has intermediate washers and slot washer. At bottom roller it is installed central washer, providing alignment of operating cross-bending stresses in blank, and intermediate washers, holding central washer against removal in horizontal direction.
EFFECT: qualitative forming of tubular billet at the expense of surface defect removal, endurance increasing of forming mill rolling tool.
