Utility
Method for altering casting roll profile with the alteration of localized temperature
20 Dec 22
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.
