Abstract: A caliber roll for rolling consisting of a roll main body having a caliber on the outer circumference and provided with a shaft hole penetrating in the axial direction, and a roll shaft inserted into the shaft hole of the roll main body, in which a compressive stress in the widthwise direction of the roll main body is applied to the bottom of the caliber. This compressive stress is applied by forming either the inner circumference of the roll main body or the circumference of the roll shaft in a taper, and shrinkage-fitting or cold-fitting the roll main body and the roll shaft, or by pressing the both end faces in the widthwise direction of the roll main body by means of a pressing jig fixed to the roll shaft. In addition, a recess gap is provided in either one or both of the inner circumference in the middle of the widthwise direction of the roll main body and the corresponding circumference of the roll shaft. The roll main body is composed of an iron-based alloy including, by weight, C: 0.75 to 1.75%, Si: 3.0% or less Mn: 2.0% or less, P: 0.30% or less, S: 0.030% or less, Cr: 5.0 to 13.00%, Mo: 0.80 to 5.0%, and V: 0.1 to 0.5%, in which the entire hardness is adjusted to H.sub.R C 52 to 56, and the metal flow is in the axial direction.

Abstract: A roll for a mill includes a roll shaft of a circular cross-section having an axis of rotation therethrough and having an outer peripheral surface. A ring of a wear-resistant material having an outer peripheral surface adapted to engage with a metal material to be rolled is disposed around the roll shaft. A tubular sleeve having an inner peripheral surface is disposed between the roll shaft and the ring with the inner peripheral surface mated with the outer peripheral surface of the roll shaft. A layer of adhesive is interposed between the ring and the sleeve for adhesively securing the ring and the sleeve together. The adhesive layer is compressed by the ring and the sleeve so as to be brought into frictional engagement therewith.

Abstract: An arrangement for fastening a roll ring (5) to an overhung roll shaft (1) by means of a taper sleeve (8) which transmits essentially the entire torque and which is loaded axially by a spring (43) supported on an abutment (47) adjustable on the free end of the roll shaft. The roll ring can be exchanged easily because of a cylinder part (21) arranged radially within the spring. This cylinder part forms a first annular cylinder space (40) for prestressing the spring, with which it interacts via a flange, and a second cylinder space (22) for drawing off the taper sleeve, to which it is connected via engagement means (28). The spring and the hydraulic devices can remain in place when a roll ring is assembled and removed, because their outside diameter is less than the bore of the roll ring.
