Abstract

A casting roll for a two-roll casting device for the casting of metallic strip from a metal melt, in particular a steel melt, includes a roll body, on a casing surface of which a coating consisting of a coating material is applied by thermal spraying, which has a higher degree of hardness than the roll body. The casting roll according to the invention and the two-roll casting device, while easy to manufacture, has not only a long service life, but also allows for the manufacture of cast strips of optimum quality. This is achieved by the fact that the free surface of the coating, after thermal spraying, has a peak number RPc of at least 10 cm−1.
