In a device for hot rolling metal wires and strip, a rolling cylinder embodying a supporting ring and a working ring mounted on the cylinder with the supporting ring having a coefficient of expansion approximating that of the working ring and a clearance between its inner periphery and its support with the working ring fitted onto the supporting ring with a clearance of not more than a few hundredths of a millimeter and means engaging the axial portions of the working ring to prevent axial displacement whereby the forces generated under operating conditions operate to apply compressive forces to the working ring. |
