Abstract
A method of continuously casting metal strip may include assembling a pair of casting rolls having casting surfaces laterally positioned to form a nip therebetween through which thin cast strip may be cast, a metal supply system capable of delivering molten steel above the nip, the casting rolls having a crown shape so that edge portions of the cast strip within 50 millimeters of edge of the cast strip have a higher temperature than the cast strip in center portions of the strip width and controlled edging up, forming a casting pool of molten steel supported on the casting surfaces above the nip and controlling side dams adjacent the ends of the nip to confine the casting pool, and forming a cast strip such that the edge portions of the cast strip within 50 millimeters of each edge of the cast strip is of a higher temperature than the strip in the center portions of the strip width.
