Abstract
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 .mu.m.
