Abstract:
The exemplary embodiments relate to the removal of cooling water used to cool the surface of an ingot as it is formed during casting. The cooling water is removed from the surface by directing jets of water onto the surface at an angle, and with a momentum, that causes the cooling water to be stripped from the surface when contacted with the jets, and to follow a path that prevents the cooling water from again coming into contact with the ingot surface at a position beyond the point of removal. The apparatus for this includes nozzles to create the water jets, and equipment for supplying water under sufficient pressure and rate of flow to the nozzles.
