A method of operation of a twin roll casting apparatus to produce thin gauge sheet metal at high-production rates. The method includes simultaneously adjusting various operating parameters, such as the roll speed, tip position, roll gap, molten metal input temperature and exit strip tension. In an iterative fashion, the strip gauge is reduced in steps while increasing the speed of the rolls and pulling the tip back out of the roll bite. In conjunction with the aforementioned adjustments, the temperature of the molten metal input to the feed tip is gradually reduced to ensure proper solidification at higher speeds. A set of pinch rolls closes on the exit strip at a certain gauge thickness to apply a drag to the strip in order to ensure proper coil wind-up tension.
