Abstract
A method is provided for directly casting molten metal from of the exit end of a casting vessel onto a moving casting surface to form a continuous strip of crystalline metal. The surface tension of the molten metal flowing from the exit forms the top, edge and bottom surfaces of the strip being cast to provide good strip surface quality, edges and structure. An apparatus is also provided including a casting vessel having a molten metal receiving end and an exit end from which a fully developed uniform flow of molten metal leaves through a U-shaped structure onto a moving casting surface. A direct cast strip product is also provided.
