Casting metal strip. |
摘要 |
Twin roll casting of metal strip (20) by rotation of parallel casting rolls (16) supplied with molten metal through distributor (19a) and delivery nozzle (19b). X-ray scanner (44) continuously scans the thickness of strip (20) to produce a signal which is a continuous measure of thickness variation along the strip due to eccentricities of the casting rolls (16). This signal controls operation of roll drive motors (53) to impose a pattern of speed variation on the rolls so as to reduce the amplitude of the thickness variations. |
