Zusammenfassung:	A METHOD OF CONTINUOUSLY CASTING METAL STRIP MAY INCLUDE ASSEMBLING A PAIR OF CASTING ROLLS (12) HAVING CASTING SURFACES (12A) LATERALLY POSITIONED TO FORM A NIP (18) THERE BETWEEN THROUGH WHICH THIN CAST STRIP (21) MAY BE CAST, A METAL SUPPLY SYSTEM CAPABLE OF DELIVERING MOLTEN STEEL ABOVE THE NIP (18), THE CASTING ROLLS (12) 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 (19) OF MOLTEN STEEL SUPPORTED ON THE CASTING SURFACES (12A) ABOVE THE NIP (18) AND CONTROLLING SIDE DAMS (20) ADJACENT THE ENDS OF THE NIP (18) TO CONFINE THE CASTING POOL (19), 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.
