Latest Patents

Grandfield holds a patent for a "Bleed out detector for direct chill casting." This invention involves a casting apparatus designed for the direct chill casting of molten metal. The apparatus includes a mold with an inlet for molten metal, a side wall, and an outlet for the withdrawal of the casting. A water spraying device is strategically positioned to direct water sprays onto the outer surface of the casting as it emerges from the outlet. Additionally, an infra-red detector is placed near the area where the water sprays impact the casting. This detector is crucial as it is exposed to radiation from the cooling process, allowing it to detect any molten metal bleeding out from the casting, which would expose the detector to high-temperature radiation.
