Abstract:
The invention relates to a speed synchronization system for an aluminum alloy slab continuously casting and rolling line having a twin-belt casting machine and skin pass rolling machine which controls the belt speed of the twin-belt casting machine and roll speed of the skin pass rolling machine. An actually measured value of a slab speed during advance from a twin-belt casting machine to a skin pass rolling machine is compared with a line speed setting to control roll speed of the skin pass rolling machine by proportional/integrated control and simultaneously control belt speed of the twin-belt casting machine based on the line speed setting and a solidification shrinkage rate of the aluminum alloy to be cast.
