Abstract:
1. A rolling mill roll comprising: a rolling mill ring made of cemented carbide having one or more rolling mill sections for milling work piece on its outer circumferential face; a ring shaped metal base located in an inner circumferential region of the rolling mill ring below the rolling mill ring on a line with the rolling mill ring perpendicular to a rotating axis of the rolling mill ring; and a tapered sleeve below the ring shaped metal base on said line perpendicular to the rotating axis; wherein a circumferential interface, where the rolling mill ring and the metal base face each other, is fixed radially around its axis by a contact pressure derived from a fitting section, and also is bound with an adhesive agent, wherein, the circumferential interface is a tapered face which slopes to the axis and is fixed with the contact pressure by wedging the metal base into the rolling mill ring, and wherein, a taper angle, at which the circumferential interface slops to the axis, is in the range of 0°10′ to 2°00′.
