A method of continuously casting metal strip having the steps of assembling a pair of counter-rotatable casting rolls, assembling a metal delivery system adapted to deliver molten metal above the nip to form a casting pool, the casting pool forming a meniscus with each casting surface of the casting rolls, delivering a shell thickness controlling gas to select areas within 300 mm of end portions of at least one casting roll downwardly toward the meniscus between the casting pool and the casting surface adapted to control thickness of the metal shell, and control attenuation of the casting roll, and sensing the temperature and thickness profiles of the cast strip downstream from the nip to determine high or low temperature areas of the cast strip within 300 mm of the end portions and causing the gas to be delivered to the high or low temperature areas to change the thickness of the metal shell.
