PROCESS AND APPARATUS FOR THE CONTINUOUS CASTING OF METAL

摘要

In a continuous casting machine having a moulding cavity formed by a pair of moving belts and a pair of side dams, casting is controlled in function of a signal which is generated by exposing a photosensitive element to a radiation transmitted by an optical device located outside the moulding cavity and pointing at the border line between the cast metal and one of the side dams. The sensitivity of the photosensitive element lies essentially within the visible spectrum and is weak for infra-red radiation.
