ABSTRACT:
Apparatus for continuously casting metal strip includes a pair of counter-rotatable casting rolls laterally positioned to form a nip therebetween through which thin strip can be cast, a pair of confining side dams adjacent the ends of the casting rolls capable of confining a casting pool of molten metal supported on the casting rolls and formed on the casting surfaces above the nip, a metal delivery system disposed above the nip and capable of discharging molten metal to form the casting pool supported on the casting rolls, side dam actuators each capable of applying cyclical axial force to the side dams without leakage, and a control system capable of actuating at least one side dam actuator to cyclically vary the apply force of the side dam against the ends of the casting rolls during a casting campaign.
