Abstract of the Disclosure An integrated process for automatically controlling the position of solidification of molten metal in the bite of rotating rolls of roll casting apparatus, the gauge of solid metal exiting the apparatus, and compensation for eccentricity in the rolls of the apparatus. The process includes a series of measuring steps that provide values indicative of solidification position, exit gauge and the frequency of roll eccentricity. The solidification position and gauge values are separately compared to reference values established for the position and gauge, with corrections being made respectively to the speed and casting gap of the rolls when differences occur between the measured and reference values. While such measuring and correcting steps are being performed the measured frequency of eccentricity is being employed to cyclically change the roll gap to offset the effects of eccentricity on the gauge of metal exiting the mill.
