Abstract:
1. A method of continuously casting metal strip comprising: assembling a pair of counter-rotatable casting rolls having casting surfaces laterally positioned to form a nip therebetween through which thin cast strip can be cast, and a metal supply system capable of delivering molten metal into a casting pool through a delivery nozzle above the nip; forming a casting pool of molten metal supported on the casting surfaces above the nip to form a casting area; sensing images of a flow of molten metal from the metal supply system into the delivery nozzle in a plurality of locations; sensing images of the casting pool in a plurality of locations in the casting area indicative of the casting pool depth in the plurality of locations; displaying the sensed images of the flow of molten metal in a plurality of locations and of the casting pool in a plurality of locations; and controlling the flow of molten metal from the metal supply system into the delivery nozzle and the casting pool responsive to the sensed images indicative of the casting pool depth.
