Abstract
Method and apparatus for casting molten metal by passing molten metal form a casting pool above the nip of the pair of chilled rollers and thence through the pair of counter rotating chilled rollers, to thus form a thin sheet of solid metal. The molten metal is delivered to the casting pool from a metal delivery nozzle which contains an outlet flow passage at the bottom thereof, below the surface of the casting pool, through which the molten metal passes into the casting pool, which further contains a diffuser therein just above the outward flow passage, and which contains a pool of molten metal sufficiently deep that its surface is above the diffuser. The diffuser had a multiplicity of flow passages (holes) therein through which the molten metal, which is fed to the delivery nozzle, passes and is diffused into the outlet flow passage. An energy absorbing baffle means may be provided above the diffuser.
