Abstract

A method of continuously casting thin strip dynamically controlling roll casting surface configuation by controlling the temperature of water flowing through the longitudinal water flow passages in a cyclindrical tube thickness of no more than 80 millimeters of counter rotated casting rolls, and varying the speed of the casting rolls with attenuation of the ends of the casting rolls with a casting roll drive system responsive to electrical signals received from sensors during a casting campaign.
