An apparatus for continuously casting thin strip has a pair of internally cooled counter-rotatable casting rolls having casting surfaces, the pair of casting rolls laterally positioned to form a gap at a nip between the casting rolls through which a thin metal strip can be cast, where the casting surface of each casting roll has a roll profile extending in an axial direction of the corresponding casting roll; a metal delivery system adapted to deliver molten metal above the nip to form a casting pool; and a temperature altering source external to the casting roll and having one or more zones configured to alter the casting roll profile of at least one of the pair of casting rolls by locally heating or cooling the casting roll.

Method for altering casting roll profile with the alteration of localized temperature

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.
