Abstract
A method and apparatus for controlling the thickness of a metal strip cast by pouring molten metal between a pair of closely spaced, water-cooled rotating rolls. The temperature of at least one of the rolls is measured at a fixed position relative to the roll bite before and during the cast. The rotational speed of the rolls is adjusted in proportion to a measured roll separation or roll separating force corrected by the roll temperature measured during the cast such that a predetermined and substantially uniform thickness of the metal strip is produced.
