Abstract
A method is provided for directly casting molten metal from a U-shaped structure of the exit end of a casting vessel onto a moving casting surface to form a continuous strip of crystalline material. The method includes radiantly cooling the molten metal in a zone defined above the molten metal, across the width of the U-shaped structure and adjacent the casting surface. The method also includes providing a non-oxidizing atmosphere in the zone.
