A casting roll for the continuous casting of thin metal strips, in particular steel strips in a double-roll or roll-in installation. The roll comprises a roll core with an external casing and an annular roll jacket with an internal casing. The jacket surrounds the core and is being shrunk onto the latter. To prevent migratory motion of the roll jacket in relation to the roll core, the surface of at least one of the opposing casings that form a shrinkage connection has protuberances and indentations, which are oriented at least partially in the direction of the casting roll axis and extend radially for at least 2 &#x3bc;m.

Casting roll and a method for producing a casting roll

In a casting roll for a thin strip casting plant, comprising an essentially cylindrical core ( ), a mantle ( ) of copper or a copper alloy optionally being provided with at least one outside layer ( ), an internal cooling system ( ) as well as an adjusting means ( ) for adjusting the outline of the casting roll in its front-end regions ( ), the adjusting means for the purpose of levelling out thermally caused crowns with the aid of constructively simple means has in each front-end region of the casting roll a supporting disk ( ) adjustable in the longitudinal direction of the casting roll and engaging a ring ( ) radially surrounding the supporting disk ( ) and abutting the mantle ( ) from the inside in its front-end regions, which ring is fixedly attached with regard to the core ( ) in the longitudinal direction of the casting roll (Fig.).
