Abstract
An apparatus for casting metal strip includes a pair of counter-rotatable casting rolls having casting surfaces laterally positioned to form a nip therebetween through which cast strip can be cast, and on which a casting pool of molten metal can be formed supported on the casting surfaces above the nip, a pair of molten metal delivery nozzles disposed above the nip and capable of discharging molten metal to form the casting pool supported on the casting rolls, a pair of side dams adjacent ends of the pair of casting rolls capable of confining the casting pool, a pair of delivery nozzle actuators capable of positioning the delivery nozzles independently of the side dams and a pair of side dam actuators capable of positioning the side dams independently of the delivery nozzles during casting, and a control system capable of controlling desired distance between the delivery nozzles and the side dams.
