Abstract
A cooling apparatus and related method for a continuous casting apparatus includes a series of spray nozzles for spraying a coolant against one surface of a moving chill substrate. The invention apparatus includes an enclosure having vacuum applied thereto for preventing migration of the sprayed coolant from the surface against which it is sprayed to the surface contacting the molten solidifying material. Any coolant having a tendency to escape along sealed edges of the enclosure is forced back into the enclosure by the pressure gradient. The edges are sealed by elongated plastic rods. Additionally, scrapers are provided for removing remanent coolant from the sprayed surface. The coolant is sprayed at a high velocity to increase its heat transferring efficiency.
