Method and apparatus for separating continuous cast strip from a rotating substrate.

摘要

The continuous casting of strip (17) ribbon and wire is improved by using a free jet nozzle (27) which provides a fluid that follows a rotating substrate (19) surface to the separation point. The nozzle (27) includes an inclined surface (31) having a ratio of its length to the gap (g) between the substrate (19) and the nozzle edge of 5:1 to 15:1. The inclined surface (31) improves the ability of the jet (25) to tangentially follow the substrate (19) in a direction opposite to its rotation to the separation point. This also allows a close positioning of the nozzle (27) to the substrate (19) which serves to provide a back-up mechanical separation means by using the edge of nozzle lip. The nozzle (27) may be rotated from its operating position for cleaning of the substrate (19) and the nozzle (27). <IMAGE>
