Abstract
A casting apparatus for direct chill casting of molten metal includes a mold having an inlet to receive molten metal, a side wall and an outlet for withdrawal of a casting from the mold, a water spraying device positioned to direct water sprays which impinge directly on an outer surface of the casting emerging from the outlet and an infra-red detector positioned adjacent a region in which the water sprays impinge directly upon the outer surface of the casting being withdrawn from the outlet of the mold. The detector is thus exposed to radiation from this region as the casting is cooled by the water sprays, and any molten metal bleeding out from the casting in this region immediately exposes the infra-red detector to high temperature radiation.
