A ring rolling mill with a rotatable annular table (4) for accommodating a collared roll with radially displaceable annular segments (9, 10) and with an eccentrically arranged, radially adjustable mandrel roll (35). The technical problem of the invention consists in designing a ring rolling mill of the type stated at the outset in such a way that high rolling forces can be applied and controlled in a structurally safe manner. A semiannular segment (9) of the collared roll is permanently connected to the annular table (4). The second semiannular segment (10) of the collared roll can be clamped to the annular table (4). A slideway (40) for the displacement of the second semiannular segment (10) is provided radially to the axis of the annular table. A yoke (27) is provided for holding the mandrel roll (35), the said yoke being displaceable in the radial direction of the annular table. Arranged transversely to the direction of displacement of the yoke (27) is an annular segment-shaped supporting wall (21) for supporting the collared roll. A hydraulic pressure cylinder (37) is arranged between the column (28) of the yoke (27) and the supporting wall (21). <IMAGE>
