Patent ID: 8141618

Claim:
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 metal strip is cast, a metal supply system capable of delivering molten steel above the nip, the casting rolls having a crown shape so that each edge portion of the metal strip within 50 millimeters of each edge of the metal strip has a higher temperature than the metal strip in center portions of the strip width; forming a casting pool of molten steel supported on the casting surfaces above the nip in a casting area and controlling side dams adjacent the ends of the nip to confine the casting pool; and forming a metal strip such that each edge portion of the metal strip within 50 millimeters of each edge of the metal strip is of a higher temperature than the metal strip in the center portions of the strip width.
