Abstract
Twin roll casting of metal strip ( ) by rotation of parallel casting rolls ( ) supplied with molten metal through distributor ( ) and delivery nozzle ( ). X-ray scanner ( ) continuously scans the thickness of strip ( ) to produce a signal which is a continuous measure of thickness variation along the strip due to eccentricities of the casting rolls ( ). This signal controls operation of roll drive motors ( ) to impose a pattern of speed variation on the rolls so as to reduce the amplitude of the thickness variations.
