Abstract
Thickness of metal sheet being cast is continuously controlled by passing a light beam through the gap between the casting machine rolls and measuring the amount of light passing through. The width of the gap is controlled in response to the measured light. To prevent interference in the hostile environment of a casting machine, the light is transmitted along an enclosed path and air is blown through the enclosed path into the roll gap. Both the thickness can be controlled in this way, and the profile can be controlled by axially shifting at least one of a pair of non-cylindrical work rolls.
