<p>A metal sheet or ribbon having a unidirectional crystalline structure is produced by continuous casting by the steps of feeding the molten metal to be cast onto the surface of a solidification support moving continuously in one direction along a given path, while heating the solidification support so that the surface thereof at the position for receiving the molten metal is at a temperature exceeding the solidification temperature of the metal being delivered thereto, and then cooling the delivered metal downstream of said position whereby the formation of crystal nuclei upon contact of the delivered molten metal is inhibited and the solid sheet or ribbon has a unidirectional crystalline structure conducive to ease in cold working without cracking.</p> |
