APPARATUS PROVIDING CONTINUOUS EXPANDABLE QUENCH SURFACE AND CASTING METHOD

摘要

APPARATUS PROVIDING CONTINUOUS EXPANDABLE QUENCH SURFACE AND CASTING METHOD An improvement is provided in the apparatus and method for continuous casting of metallic filament wherein a stream of molten metal is directed onto the quench surface of a rotating quench wheel. The invention substantially eliminates the problem of crowning or thermal-bowing of the quench surface, thus providing a transversely flat quench surface and thereby providing for the transverse cross-sectional constancy of the cast filament. The invention comprises at least three radial expansion joints symmetrically situated about the quench wheel that allow unrestrained radial thermal growth of the hoop-like quench surface while maintaining concentricity of the quench surface with the shaft of rotation of the quench wheel.
