Claims
- 1. Method of directly casting molten metal to continuous strip of crystalline metal, comprising:
- flowing molten metal from a generally U-shaped structure of an exit end of a casting vessel onto an adjacent casting surface, the structure having edges substantially parallel to the casting surface and having a planar bottom wall and diverging inside sidewalls opening upwardly;
- moving the casting surface generally upwardly past the exit end of the casting vessel at a predetermined distance therefrom to solidify the molten metal into strip form; and
- additionally facilitating radiant cooling of the molten metal by a cooling means spaced from and in a zone defined above the molten metal top surface to extract heat therefrom, across the width of the U-shaped structure and adjacent the casting surface to affect the as-cast strip surface quality and structure.
- 2. An apparatus for directly casting molten metal to continuous strip of crystalline metal, comprising:
- movable casting surface upon which molten metal solidifies into strip form;
- casting vessel having an exit end including a U-shaped structure for flowing molten metal onto the moving casting surface adjacent thereto at a predetermined distance, the structure having edges substantially parallel to the casting surface and having a planar bottom wall and diverging inside sidewalls opening upwardly; and
- means for facilitating radiant cooling of the molten metal, said cooling means being spaced from and in a zone defined above the molten metal top surface to extract heat therefrom, across the width of the U-shaped opening and adjacent the casting surface to affect the as-cast strip surface quality and structure.
- 3. The apparatus of claim 2, wherein the means includes at least one tube having a circulating coolant therein.
